Haggar’s classic-fit separates offer a more forgiving fit. For a complete three-piece outfit, MAGE MALE bundles a blazer, vest, and pants; Michael Kors offers another three-piece option with a more established designer label. The main tradeoffs are slim versus classic proportions, stretch or performance fabrics versus wool, and separates versus a set.

Key Takeaways
Calvin Klein’s performance wool suit earns the overall lead by pairing a traditional wool fabric with a slim silhouette; its fit may feel restrictive to buyers who prefer room through the seat and thigh.
J.M. Haggar’s classic-fit separates offer the clearest alternative for buyers who prioritize ease of movement and a less tapered shape.
Suit separates matter when proportions differ: Calvin Klein, Tommy Hilfiger, DKNY, and Haggar options let buyers choose jacket and trouser sizes independently.
Three-piece sets solve a specific styling need: MAGE MALE includes blazer, vest, and pants, while Michael Kors is the lineup’s classic-fit three-piece option.
The lineup favors slim and modern cuts, so buyers seeking a relaxed or traditional silhouette should start with Haggar or Michael Kors rather than choosing by brand name alone.

More Details on Our Top Picks
Calvin Klein Men’s Slim Fit Suit Separate Jacket
A trimmer silhouette and separately sold jacket make this Calvin Klein a useful pick for buyers who need more control over fit. Its wool blend includes polyester and spandex, adding stretch while keeping wool as the main fiber. Compared with the Tommy Hilfiger TH Flex Modern Fit Suit Separates Jacket, this one is the clearer choice for a slim cut; Tommy Hilfiger is better suited to buyers who want an athletic modern shape and named mobility features.
The tradeoff is that this listing covers the jacket only, so matching pants require a separate purchase and sizing decision. Dry-clean-only care also means more upkeep than an easy-care option. I’d choose it for a streamlined business or formal wardrobe when jacket and trouser measurements differ, but skip it if you want a complete suit in one purchase.
Pros:- Separate sizing lets you pair the jacket with matching pants in a different size.
- Slim cut, higher armholes, and tapered sleeves create a close, modern profile.
- Wool blend with spandex offers some natural give.
- Suitable for business and formal occasions.
Cons:- Matching pants are sold separately.
- Dry-clean-only care adds maintenance effort.
- Slim proportions may feel restrictive to buyers who prefer more room through the chest and sleeves.
Best for: Men who prefer a close, contemporary jacket and need to choose jacket and trouser sizes independently.
Not ideal for: Buyers who want a complete suit in one purchase or prefer machine-washable clothing.
- Fabric:70% wool, 25% polyester, 5% spandex
- Fit:Slim
- Care:Dry clean only
- Pieces:Jacket sold separately
- Origin:Imported
- Style details:Higher armholes, trimmer chest, tapered sleeves
Our verdict“Choose this jacket if you want a modern slim silhouette and separately sized suit pieces, and can manage the added care and separate trouser purchase.”
Tommy Hilfiger Men’s TH Flex Modern Fit Suit Separates Jacket
TH Flex stretch fabric gives this Tommy Hilfiger jacket a mobility-focused role in the lineup. Its athletic modern fit, higher armholes, and trimmer sleeves aim for a shaped look with room to move. Compared with the Calvin Klein Men’s Slim Fit Suit Separate Jacket, this jacket puts more emphasis on movement and an athletic fit than on a distinctly slim silhouette. The two-button front, notched lapel, and side vents keep its styling familiar for business and formal settings.
The separates format lets buyers choose jacket and trouser sizes independently, but the jacket is only one part of the suit; matching pants and vest are sold separately. Recycled polyester is part of the fabric blend, while the wool content remains substantial. Dry-clean-only care is the main upkeep drawback. This makes more sense for buyers who move throughout the workday than for anyone seeking a complete suit with minimal separate purchases.
Pros:- TH Flex fabric is designed to support movement and comfort.
- Athletic modern fit pairs higher armholes with trimmer sleeves.
- Separates allow independent jacket and trouser sizing.
- Fabric blend includes recycled polyester.
Cons:- Matching dress pants and vest are sold separately.
- Dry-clean-only care requires extra upkeep.
- Athletic modern proportions may not suit buyers seeking a conventional or relaxed fit.
Best for: Men with athletic proportions who want a shaped jacket with stretch and the option to size trousers separately.
Not ideal for: Buyers who need a complete suit set or want a jacket cut specifically for a close slim fit.
- Fabric:52% wool, 45% recycled polyester, 3% Lycra spandex
- Lining:Polyester
- Fit:Athletic modern fit
- Closure:Two-button
- Lapel:Notched
- Vents:Side vents
- Care:Dry clean only
- Pieces:Jacket; matching vest and dress pants sold separately
Our verdict“Pick this jacket if mobility and an athletic modern cut matter more than getting a full suit together at once.”
Calvin Klein Men’s Slim Fit Suit Separates
100% wool with natural stretch sets this Calvin Klein apart from the lineup’s polyester-led options. The slim cut, higher armholes, trimmer chest, and tapered sleeves give it a more tailored profile than the Kenneth Cole New York Performance Fabric Slim Fit Suit, which includes both jacket and pants and uses a polyester, rayon, and spandex blend. Here, the benefit is a wool suit fabric and the ability to choose jacket and trouser sizes separately.
That fit flexibility has a practical cost: the jacket and pants are sold separately, so completing the outfit takes another purchase. Dry cleaning is also required, and wool may not suit buyers who prioritize simple home care. I’d look to this option for a repeat-wear business wardrobe where natural-fiber composition and separate sizing matter more than getting a full set in one package.
Pros:- Made from 100% wool with natural stretch.
- Separate pieces allow independent jacket and trouser sizing.
- Slim profile includes higher armholes and tapered sleeves.
- Wool fabric is described as suitable for year-round wear.
Cons:- Jacket and pants must be purchased separately.
- Dry-clean-only care requires professional upkeep.
- Close slim proportions may not suit buyers who prefer a relaxed fit.
Best for: Men who want a wool slim-fit suit and need different sizes for their jacket and trousers.
Not ideal for: Buyers seeking a complete suit set, easy-care fabric, or a roomier cut.
- Fabric:100% wool
- Fit:Slim fit
- Fabric feature:Natural stretch
- Care:Dry clean only
- Pieces:Suit separates; jacket and pants sold separately
- Origin:Imported
- Style details:Higher armhole, trimmer chest, tapered sleeve
Our verdict“Choose these separates if wool and independent sizing matter more to you than a one-purchase suit or easier care.”
Kenneth Cole New York Men’s Performance Fabric Slim Fit Suit
Jacket and pants come together here, giving the Kenneth Cole a simpler route to a coordinated slim-fit suit than the Calvin Klein and Tommy Hilfiger separates. Its polyester, rayon, and spandex fabric blend is designed for stretch and breathability, while notched lapels, a two-button closure, and side vents keep the look traditional enough for varied events. Compared with the Calvin Klein Men’s Slim Fit Suit Separates, this trades 100% wool and separate sizing flexibility for a complete two-piece set.
The included trousers simplify buying, but the provided sizing guidance—subtracting seven from chest measurement for pant waist—may take extra attention. Dry-clean-only care also limits convenience, and the synthetic-heavy blend will not appeal to buyers seeking a wool suit. This is the more straightforward pick when coordinated jacket and pants matter more than natural fiber or independent sizing.
Pros:- Includes both jacket and matching pants.
- Stretch blend is designed to support movement and breathability.
- Slim fit uses familiar details including notched lapels and side vents.
- Jacket has functional interior and exterior pockets.
Cons:- Dry-clean-only care adds upkeep effort.
- Polyester-based fabric may not suit buyers seeking wool.
- Pant sizing guidance may require extra attention.
Best for: Men who want a coordinated slim-fit jacket and trouser set for business or formal events.
Not ideal for: Buyers who need a wool suit, separate jacket and trouser sizing, or easy-care clothing.
- Fabric:68% polyester, 30% rayon, 2% spandex
- Fit:Slim fit
- Set includes:Jacket and pants
- Care:Dry clean only
- Closure:Two-button
- Lapel:Notched
- Vents:Side vents
- Origin:Imported
Our verdict“Pick this set when you want matching slim-fit jacket and pants together and are comfortable with synthetic fabric and dry cleaning.”
Three coordinated pieces in one set give this MAGE MALE suit a distinct role: it includes a blazer, vest, and pants, while the Calvin Klein and Tommy Hilfiger separates require buyers to assemble pieces individually. An adjustable vest back tie and trouser waistband offer some fit flexibility, useful for event wear when a fixed waist fit is less convenient. The polyester-viscose blend and slim silhouette are aimed at occasions such as weddings, parties, graduations, and proms.
Compared with the Kenneth Cole New York Performance Fabric Slim Fit Suit, this adds a vest but uses a one-button blazer rather than the more conventional two-button style. The fabric is polyester-based rather than wool, and care guidance still calls for dry cleaning, with limited hand washing as a fallback. I’d choose it for a coordinated three-piece event outfit, but skip it for a wool-first business wardrobe.
Pros:- Includes blazer, vest, and pants as a coordinated set.
- Adjustable vest back tie and trouser waistband add fit flexibility.
- Slim fit and notch lapel create a shaped formal look.
- Polyester-viscose blend is described as breathable.
Cons:- Polyester-based fabric lacks the wool composition of several separates in the lineup.
- Care calls for dry cleaning, with hand washing only as a limited alternative.
- One-button blazer offers a different, less traditional look than the two-button Kenneth Cole and Tommy Hilfiger jackets.
Best for: Men preparing for weddings, proms, graduations, or parties who want a blazer, vest, and pants together.
Not ideal for: Buyers seeking a wool suit, traditional two-button jacket, or straightforward machine-wash care.
- Fabric:80% polyester, 20% viscose
- Lining:100% polyester
- Pieces:Three: blazer, vest, pants
- Fit:Slim fit
- Blazer closure:Single-breasted, one button
- Lapel:Notch lapel
- Vest:V-neck, four buttons, adjustable back tie
- Pants:Adjustable waistband
- Care:Dry clean; hand wash below 40°C (104°F) if needed
Our verdict“Choose this set for a coordinated three-piece outfit for special events if its synthetic blend and one-button styling suit your needs.”
Calvin Klein Men’s Slim Fit Performance Wool Suit
Stretch comfort with familiar tailoring gives this Calvin Klein suit a useful middle ground for buyers who want a slimmer silhouette without a rigid feel. Its two-button jacket, notched lapels, and flat-front pants keep the look conventional enough for meetings and weddings, while the spandex in its wool blend adds flexibility through a long day. Compared with the Calvin Klein Men’s Slim Fit Suit Separates, Blue Twill, this suit comes as a coordinated suit rather than separates, but its fabric contains less wool. The tradeoff is straightforward: you gain stretch and a ready-to-pair set, while accepting a polyester-heavy blend and dry-clean-only care. I’d choose it for recurring formal occasions when movement matters more than an all-wool composition.
Pros:- Spandex blend adds flexibility for extended wear
- Two-button jacket and notched lapels suit business and formal settings
- Flat-front pants create a clean, streamlined profile
Cons:- Fabric is only 52% wool, with polyester making up most of the remainder
- Jacket and pants are not described as independently selectable
- Dry-clean-only care
Best for: Slim-fit buyers who want stretch for long workdays and formal events in a coordinated suit.
Not ideal for: Shoppers prioritizing a high wool content or independently sized jacket and pants.
- Brand:Calvin Klein
- Fit:Slim fit
- Fabric:52% wool, 46% polyester, 2% spandex
- Jacket:Two-button closure with notched lapels
- Pants:Flat front
- Care:Dry clean only
- Origin:Imported
Our verdict“Choose this Calvin Klein when you want a slim, stretch-friendly suit for varied formal occasions and can accept a blended fabric.”
DKNY Men’s Modern Fit High Performance Suit Separates
Independent jacket and pant sizing is the main reason to choose this DKNY: it can accommodate buyers whose top and bottom sizes do not match neatly. The modern fit is slightly tapered, and four-way stretch with elastic yarn is designed to make sitting, walking, and commuting easier. Compared with the J.M. Haggar Premium Stretch Classic Fit Suit Separates, DKNY offers four-way stretch and a trimmer shape, while Haggar gives more room through the chest and arms. Its fabric is mostly polyester and viscose, so it is a less natural-fiber choice than the wool options in this roundup. The separate pieces also mean more decisions when assembling a suit, and both require dry cleaning. This pick suits movement and sizing flexibility over wool content or one-box convenience.
Pros:- Jacket and pants can be sized separately
- Four-way stretch supports freedom of movement
- Slightly tapered modern fit
Cons:- Jacket and pants are sold separately
- Fabric is primarily polyester and viscose
- Dry-clean-only care
Best for: Men who need to choose jacket and trouser sizes independently and prefer a tapered modern fit with stretch.
Not ideal for: Buyers who want a complete coordinated suit in one purchase or prioritize wool-rich fabric.
- Brand:DKNY
- Fit:Modern fit, slightly tapered
- Fabric:68% polyester, 28% viscose, 4% spandex
- Stretch:Four-way stretch with elastic yarn
- Set contents:Jacket and pants sold separately
- Care:Dry clean only
- Origin:Imported
Our verdict“Pick DKNY if separate sizing and four-way stretch matter more to you than wool content or buying a complete suit together.”
J.M. Haggar Premium Stretch Classic Fit Suit Separates
More room through the chest and arms sets this Haggar apart from the slimmer Calvin Klein separates in the lineup. Its classic cut favors ease over a close, tapered outline, while the polyester, viscose rayon, and elastane blend supplies some give for office days or formal events. Buying the jacket and pants separately lets you address mismatched sizing, much like the DKNY Men’s Modern Fit High Performance Suit Separates; DKNY, though, is slightly tapered and specifies four-way stretch. Haggar’s jacket details—the center vent, flap pockets, and notched lapel—keep the styling traditional. The tradeoff is a synthetic-rich fabric and the extra work of selecting two pieces. Dry-clean-only care also makes it less convenient for frequent wear.
Pros:- Classic fit offers more room through chest and arms
- Separate sizing helps accommodate different jacket and pant proportions
- Stretch blend supports movement during office and formal wear
- Traditional jacket details include a center vent and flap pockets
Cons:- Jacket and pants must be selected separately
- Fabric is mostly polyester and viscose rayon
- Dry-clean-only care
Best for: Men who prefer a traditional, roomier cut and need to choose jacket and trouser sizes independently.
Not ideal for: Buyers seeking a close slim silhouette, wool-rich fabric, or a complete suit sold together.
- Brand:J.M. Haggar
- Fit:Classic fit
- Fabric:64% polyester, 34% viscose rayon, 2% elastane
- Closure:Button
- Jacket features:Two-button front, notched lapel, center vent, flap pockets, piped interior
- Set contents:Jacket and pants sold separately
- Care:Dry clean only
- Origin:Imported
Our verdict“Choose Haggar for a roomier traditional fit and separate sizing, especially if a tapered silhouette is not your preference.”
Calvin Klein Men’s Slim Fit Suit Separates, Blue Twill, 42 Regular
All-wool fabric and a close cut make this Calvin Klein the clearest choice here for buyers focused on natural fiber and defined tailoring. The higher armhole, trimmer chest, and tapered sleeve create a neater outline than the roomier J.M. Haggar Premium Stretch Classic Fit Suit Separates, while separate sizing lets you match jacket and pant proportions. Its blue twill offers a distinct look from the charcoal-neutral styling many suit shoppers choose, and the listing describes natural stretch for year-round wear. Compared with the Calvin Klein Performance Wool Suit, it has a higher wool content, but it lacks the convenience of a coordinated full set. You’ll need to source both pieces and arrange dry cleaning, so this option rewards careful fit choices rather than quick, simple purchasing.
Pros:- 100% wool fabric
- Separate pieces allow independent sizing
- Higher armhole, trimmer chest, and tapered sleeve create a close silhouette
- Blue twill offers an alternative to more conventional suit colors
Cons:- Jacket and pants must be purchased separately
- Dry-clean-only care
- Slim fit may feel restrictive to buyers who prefer room through the chest
Best for: Slim-fit buyers who prioritize 100% wool and want to select jacket and trouser sizes separately.
Not ideal for: Shoppers who want a coordinated suit in one purchase, an easy-care garment, or a roomier cut.
- Brand:Calvin Klein
- Fit:Slim fit
- Fabric:100% wool
- Color and weave:Blue twill
- Size:42 Regular
- Set contents:Jacket and pants sold separately
- Care:Dry clean only
- Origin:Imported
Our verdict“Choose this blue-twill Calvin Klein if all-wool fabric and a close fit are priorities and you are comfortable assembling the suit from separates.”
Michael Kors Men’s Classic Fit 3-Piece Suit
A blazer, vest, and pants in one classic three-piece design give this Michael Kors suit a more formal presence than the two-piece Calvin Klein Performance Wool Suit. Natural stretch in its wool-polyester blend adds some flexibility, while the classic fit favors a less tapered outline. That combination suits buyers who want a vest for ceremonies, presentations, or occasions where a jacket alone feels too simple. The fabric is 70% wool, a higher share than the Calvin Klein Performance Wool blend, though below the 100% wool Calvin Klein separates. There is a practical catch: the listing instructs shoppers to add each piece separately, so the three-piece look may involve multiple selections. Dry cleaning is also required. I’d favor it for traditional styling over streamlined everyday versatility.
Pros:- Includes blazer, vest, and pants for a traditional three-piece look
- 70% wool fabric blend
- Natural stretch adds flexibility
- Classic fit avoids a close, tapered silhouette
Cons:- Pieces must be added separately according to the listing
- Polyester makes up 30% of the fabric
- Dry-clean-only care
Best for: Men seeking a classic-fit suit with a vest for weddings, formal events, or business occasions.
Not ideal for: Buyers who want a single, ready-to-buy set, a slim silhouette, or 100% wool fabric.
- Brand:Michael Kors
- Fit:Classic fit
- Fabric:70% wool, 30% polyester
- Pieces:Blazer, vest, and pants
- Stretch:Natural stretch
- Closure:Button
- Care:Dry clean only
- Origin:Imported
Our verdict“Choose Michael Kors for a classic three-piece appearance and vest, provided you are willing to select the pieces separately.”
How We Picked
I compared these ten options on the factors that change how a suit works for its buyer: cut, fabric description, whether jacket and pants can be sized separately, and whether the outfit includes a vest. I gave more weight to versatility and the ability to get a balanced fit than to a brand label by itself. The Calvin Klein performance wool suit ranks first for combining a familiar slim profile with wool; J.M. Haggar ranks as a strong alternative for classic-fit comfort. Separate pieces rank well for buyers whose jacket and trouser sizes differ, while fixed sets stand out when a coordinated three-piece outfit is the priority.
The ranking also reflects meaningful limits. Slim cuts can feel close through the body, performance fabric descriptions do not tell buyers how a garment will feel in person, and a three-piece set may offer less flexibility than separates. Several listings come from the same brands, so I distinguish them by fit, fabric, and outfit format rather than treating each brand as a single uniform choice. Product details here are based on the supplied names and descriptions; they do not establish construction quality or fit beyond those stated attributes.

Factors to Consider When Choosing Best Men’s Suit Brands
Choosing among suit brands starts with how you need the suit to fit and function, then narrows to fabric and outfit format. These broader checks can prevent a familiar mistake: choosing a label or silhouette first and discovering that the proportions or care needs do not suit your wardrobe.
Choose the cut for your proportions
A slim or modern label describes a closer outline, but it does not guarantee that the jacket and trousers will suit your build. Pay attention to shoulder width, jacket closure, trouser rise, and room through the seat and thighs when checking a size chart. A jacket that pulls at the button or trousers that bind when seated are signs the cut may be too close. Classic fit generally leaves more ease, which can matter for long workdays or frequent movement. Buyers between sizes should check the garment measurements and return terms before ordering. Do not assume that sizing up everywhere fixes a mismatch, since an oversized shoulder can look untidy even when the waist feels better.
Decide whether separates solve a real fit problem
Suit separates let you choose jacket and trouser sizes independently, which is useful when your upper and lower body do not fit standard proportions. That flexibility can matter more than a small difference in fabric description because a well-fitting suit is easier to wear and alter. Check that the jacket and trousers are explicitly sold as compatible separates and confirm whether both pieces are included in the listing. Matching color names alone may not guarantee identical fabric batches or finish. If your measurements are close to standard sizing, a single coordinated suit can be simpler. Avoid ordering pieces from different lines without checking their cut and fabric details.
Match fabric to wear frequency and care
Wool, stretch, and performance fabric labels point to different priorities, but the name alone cannot tell you the full feel, weight, or drape. Wool may suit buyers seeking a traditional suit fabric, while stretch or performance descriptions suggest a focus on movement or practical wear. Check the care label, lining details, and fabric composition before deciding how often you can wear the suit. A suit that needs more careful upkeep may be a poor fit for daily commuting, even if its fabric appeals for formal occasions. For a first suit, versatility across work, weddings, and other events can matter more than a specialized fabric feature. When the listing leaves care or composition unclear, treat that as a reason to verify details before purchase.
Pick a two-piece or three-piece format deliberately
A two-piece suit covers most office and event needs with a jacket and matching trousers. A vest adds another layer and gives a three-piece outfit a more formal, coordinated look. It can also make the suit warmer and less adaptable in hot settings. Check whether the vest is included and whether its cut works comfortably beneath the jacket. A bundled set is convenient, but it may not let you size each piece independently. Choose three pieces for occasions where the extra layer serves your style or dress code, rather than assuming more pieces automatically make a better suit.
Budget for alterations and check the return window
Even a suit in the right labeled size may need sleeve, trouser, or waist adjustments. Plan for those changes when comparing options, particularly if the listing offers limited flexibility between jacket and trouser sizes. Alterations usually work best when the shoulders and jacket length are already close, since those areas are harder to reshape. Check the return window and whether alterations affect eligibility before taking a new suit to a tailor. If you are buying for a fixed event date, leave enough time for fitting and adjustments. A lower-cost suit that cannot be returned after alteration may carry more fit risk than a flexible option.
Frequently Asked Questions
Which suit in this roundup is the best first suit?
I would start with Calvin Klein’s slim-fit performance wool suit if a close, polished silhouette suits your build and you want a wool option. If you prefer more room, J.M. Haggar’s classic-fit separates are a more forgiving starting point. Before choosing, check whether the suit’s care needs and cut fit the settings where you expect to wear it. A first suit should work across more than one occasion, so a neutral color and a comfortable fit can matter more than a distinctive detail. Check the size chart and return terms before ordering.
Should I choose suit separates or a complete suit?
Choose separates when your jacket and trouser sizes differ enough that one standard suit size is unlikely to fit both well. This roundup includes separates from Calvin Klein, Tommy Hilfiger, DKNY, and J.M. Haggar, giving buyers several cut and fabric directions. A complete suit can be simpler when your proportions match standard sizing and you want the pieces supplied as a coordinated outfit. Verify what the listing includes, since a jacket-only separate is not a full suit. Compare measurements and compatibility before combining pieces.
Is a slim-fit suit a safe choice if I am unsure about fit?
A slim fit is a good choice only if you want a closer outline and can move comfortably in it. The label does not establish how much room the garment has, and cuts can differ between brands. Check jacket measurements, trouser waist and seat, and the return policy rather than relying on your usual size alone. If you favor more ease or plan to wear the suit for long days, a classic fit such as J.M. Haggar’s may be a better direction. A tailor can adjust some areas, but shoulder fit is difficult to change.
When is a three-piece suit worth choosing?
A three-piece suit makes sense when you want a vest as part of the outfit, such as for a formal event or a more dressed-up look. MAGE MALE and Michael Kors are the set options in this roundup, with different stated fit profiles. The vest adds warmth and another fit requirement, so it may be less comfortable in hot weather or beneath a close-fitting jacket. Check whether all pieces are included and whether their measurements suit you. For routine office wear, a two-piece suit may be easier to wear across seasons.
What should I check before ordering a suit online for an event?
Start with the event date, then check the size chart, return deadline, and any stated care requirements. Leave time for delivery, a try-on, and possible alterations; a suit that arrives just before an event leaves little room to correct fit problems. Confirm whether the listing is for a jacket, separates, or a complete outfit, since those formats are easy to confuse. If you are considering a set, verify that every included piece fits your measurements. Keep tags and packaging until you know the fit works and the return terms allow it.
Conclusion
For the best overall balance, I recommend Calvin Klein’s slim-fit performance wool suit to buyers who want a polished, closer cut and prefer wool. Best for value-minded fit flexibility: J.M. Haggar’s classic-fit separates suit buyers who need more room or separate jacket and trouser sizing. Best premium-label direction: Michael Kors offers a classic-fit three-piece set for buyers who want a vest and a designer label. Best for beginners seeking a complete set: MAGE MALE supplies blazer, vest, and pants together, though buyers should check sizing and return details carefully. For a specific separates need, compare Tommy Hilfiger and DKNY with the Calvin Klein separates listings by cut and fabric; choose the option whose measurements fit, not the name that sounds most familiar.
