Most of the plus-size women I fit for swimwear have spent years being handed boring black suits with a skirt sewn on. That has changed. Suits in extended sizes now use power mesh linings, real underwire, ruching and cuts that move with the body, and many lines run well past 3X. Fit still decides everything, though, so I care less about the label on the tag and more about the band, the straps and the torso length. Below are 30 swim outfits, from high-waisted bikinis and tummy-control one-pieces to swim dresses and rashguard sets, each with the cover-up, shoes and bag I'd put with it.
Sizing a Swimsuit by Your Bra and Torso Length
Dress size is a rough starting point for swimwear and little more. The two things that decide whether a plus-size suit is comfortable are bust support and torso length, and neither shows up on a standard size chart.
Bust first
If you wear a D cup or above, look for suits sold in bra sizes, or at least in cup groups like D/DD. A suit with a real underwire and a band you can feel holding you is a different experience from a shelf bra. The band should sit level and snug; if you can pull it more than a couple of inches away from your back, it won't support you once the fabric is wet.
Then the torso
One-pieces fail most often because the torso is too short. The straps dig, the leg openings ride up and the suit pulls down the bust. Before buying, measure from the top of one shoulder, down through the crotch and back up to the same shoulder. If that number runs long for your size, look for long-torso versions or switch to a tankini, which has no torso length to get wrong.
- Squat and lift both arms in the fitting room. Nothing should cut in or slide.
- Suits loosen a little in water, so a snug fit when dry is right.
- If the straps leave deep red marks after ten minutes, the suit is carrying the bust from the shoulders, not the band.
1. High-Waisted Bikini With Sheer Sarong
High-waisted bottoms give gentle compression over the stomach while you keep the ease of two pieces. The waistband should land at your natural waist, the narrowest point, not just under it; a band that stops on the soft part of the belly rolls down the minute you sit. I'd pair an underwire top in a color-block or floral with matching bottoms and knot a sheer printed sarong loosely at the hip. Flat leather sandals, tortoiseshell sunglasses and a straw tote get you from the sand to a boardwalk lunch without changing.
2. Ruched One-Piece Swimsuit With Wide-Brim Hat
Ruching is the detail I recommend most for a first plus-size suit, because the gathers hide the way fabric shifts over a soft stomach when you move. A V-neck and adjustable straps let you set the lift yourself. Check the ruching runs on a diagonal or down the side seams; gathers bunched straight across the middle add a band of bulk. A wide-brim straw hat, cat-eye sunglasses and slides finish a pool day, and the hat gives your face real shade.
3. Underwire Bikini Top With High-Waist Bottoms
Soft cups give a fuller bust almost nothing to sit on, which is why I send bigger busts to underwire tops sized like bras. The band should be firm and sit level all the way round; if it rides up at the back, go down a band size, not up. Wide straps spread the weight off the shoulders. With high-waist bottoms and an open linen shirt over the top, you can walk into a café without feeling undressed. Braided sandals, a canvas tote and gold hoops keep it simple.
4. Tankini With Swim Shorts For Active Days
I put women who plan to actually move in a tankini and swim shorts. A built-in shelf bra or hidden underwire and a racerback stop the top shifting when you lift your arms. On the shorts, a wide waistband holds better than a thin elastic one, and a short inseam with a slight grip stops them creeping up the thigh. Sporty slides, a cap and a waterproof crossbody suit water parks, kayaking or a splash pad with kids. Two pieces also make bathroom breaks far less awkward.
5. Wrap-Front One-Piece Swimsuit
A wrap-front or surplice neckline makes a V that runs the eye up the body and pulls in at the waist. The crossover fabric gives you room to adjust coverage at the bust, which matters if one side sits differently from the other. Jewel tones like emerald and sapphire hold their depth in strong sun better than pale shades do. I'd add strappy flat sandals, layered gold necklaces and an airy kimono. This cut suits apple, hourglass and pear shapes, since it narrows wherever you are narrowest. It takes you from the beach to a sunset dinner on a trip.
6. Halter One-Piece Swimsuit With Straw Tote
A halter lifts the bust from the neck rather than the shoulders and frames the face. The trade-off is weight on the neck: with a very full bust, a thin halter tie can give you a sore neck by the afternoon, so look for a wide halter band or one that converts to straps. A deep V and tummy-control panel keep the front smooth. The halter also widens the shoulder line a little, which balances fuller hips. A woven straw tote, espadrilles and a cotton sarong are enough for a lounger and a book.
7. Swim Dress With Wedge Sandals
A swim dress is a one-piece with a skirt overlay, and for anyone who worries about thighs it's the most relaxed choice on this list. Make sure there's a built-in brief underneath and that the skirt ends at upper thigh or just above the knee; longer skirts cling when wet and drag in sand. A V-neck keeps it from looking matronly. I'd add cork wedges, a denim jacket over the shoulders and chunky resin earrings, so you can sit down to a resort lunch and still swim after.
8. Cutout Monokini With Sheer Kimono Cover-Up
A cutout monokini gives you the shape of a two-piece but keeps the security of a one-piece. Side or waist cutouts mark the narrowest part of the torso without baring the stomach. Before buying, I check that the edges of each cutout are lined or bound; raw-edge cutouts dig into soft skin and leave red marks by the end of the day. Medium coverage and a built-in bra keep it wearable. A sheer printed kimono that floats behind you, metallic sandals, thin bracelets and round sunglasses suit a beach party or a honeymoon.
9. Bandeau Bikini Top With High-Waist Floral Bottom
A bandeau gives you a clean strapless neckline and no strap tan lines, but on a fuller bust it only works with real structure inside. I won't recommend one without a wide silicone grip strip, molded cups and a removable halter strap for the moment you get in the water. Floral high-waist bottoms carry the eye downward and add color. A sheer white cover-up dress, flat gladiator sandals, a shell pendant and a bright beach bag finish it.
10. Plunging V-Neck One-Piece Swimsuit
A plunging V lengthens the torso and opens the neckline, and it's more wearable on a fuller bust than people expect, as long as there's an underwire or molded cups holding things in place. I'd skip it if you only want a gentle plunge and the suit has no center support; the fabric spreads apart once it's wet. A tummy panel smooths without flattening. A crochet cover-up dress, neutral heeled sandals and drop earrings make it right for a destination wedding weekend or an anniversary trip.
11. Retro 1950s Swimsuit With Cat-Eye Sunglasses
A vintage-inspired ruched swimsuit borrows its shape from the 1950s: sweetheart neckline, halter ties, ruching across the waist, a skirted bottom and underwire in the bust. That construction makes an hourglass shape almost on its own, and the skirt gives extra coverage at the top of the thigh. To play up the retro side, I'd go with cat-eye sunglasses, red lipstick, cork wedges and a printed hair scarf. It suits a backyard pool party or a vintage-themed day, and polka dots or gingham push the look further.
12. Sporty Racerback One-Piece With Slide Sandals
This one is for real swimming. A racerback one-piece with a higher neck and a modest leg stays put through laps, snorkeling or a paddleboard fall. Chlorine eats regular spandex, so for pool swimmers I look for a polyester or PBT blend sold as chlorine resistant; it lasts many more seasons in a pool. A shelf bra is fine for a smaller bust, but bigger busts need a suit with a proper sewn-in bra. Quick-dry slides, a cap and a mesh bag make sense for a whole day in and out of the water.
13. Rashguard Set With UPF Hat
For long sun days, a two-piece rashguard set with long sleeves and high-waist bottoms covers you without much effort. Choose UPF 50+ fabric, a built-in bra and a front zip; a pullover rashguard is hard to peel off when it's wet and stuck to you. Snorkeling and surf lessons are where this set earns its place, since your back is out of the water and getting sun for hours. Add a UPF wide-brim hat, polarized sunglasses and sport sandals. The tropical prints and color-blocking available now look nothing like the stiff rash vests of years ago.
14. Long-Sleeve One-Piece Swimsuit
A long-sleeve one-piece covers the arms and still looks sleek. A deep scoop back keeps it from feeling like a wetsuit, and seaming at the waist gives it shape. A dark solid streamlines; a bold single-color print adds energy without busy pattern. The front zip makes it easier to get on, and the open back keeps you from overheating. A woven belt bag, minimal sandals and a newsboy cap suit a beach walk or a holiday somewhere the sun is fierce.
15. High-Neck Bikini With High-Waist Bottoms
A high neck gives sporty coverage and much better support for a large bust than a triangle or scoop. Look for a crisscross or racerback strap at the back and a wide band underneath. The high neckline adds width to the shoulders, which balances fuller hips, and high-waist bottoms sitting above the navel mark the waist. I'd add a sheer sarong skirt, mirrored aviators and slides. It's the bikini I'd pick for beach yoga, because nothing slips when you bend.
16. Boyleg One-Piece Swimsuit
A boyleg one-piece covers more of the thigh and has a sporty cut that many plus-size women prefer for comfort. The main practical win is chafing: the short leg covers the inner thigh, so there's no rubbing on a long beach walk. Check that the leg opening has a soft band; a tight one digs in and creates a bulge. A zip front, racerback and built-in bra add security. A terry cover-up, platform flip-flops, a visor and a waterproof watch fit paddleboarding and beach runs.
17. Floral Print Swimsuit With Matching Pareo
Florals do some of the styling for you. A twist-front one-piece with adjustable straps and a tummy panel in a tropical print reads as holiday the minute you put it on. Mid-size and large prints are more forgiving than tiny busy ones, which can look crowded on a bigger body. For the pareo, pick one color from the print and go solid, or use the matching print for a set. Espadrille wedges, a shell anklet and hoops fit a cruise or a resort trip.
18. Black One-Piece With Gold Accessories
Every swim wardrobe needs one black suit, and I'd spend the most money here. Shaping mesh lining, a sweetheart neckline and wide straps are what separate a well-made black one-piece from a flat one. Cheap black fabric often fades to gray or turns slightly see-through once it's stretched and wet, so hold it up to the light before buying. Gold does the styling: layered chains, gold hoops, metallic sandals and a straw clutch. A white linen cover-up adds contrast for walking from the pool to the bar.
19. Striped Two-Piece With Linen Cover-Up
Stripes need a bit of thought. Vertical or diagonal stripes run the eye up and down, while wide horizontal bands across a full bust or stomach do the opposite. A navy and white underwire top with plain high-waist bottoms is a safe start. Throw an oversized white linen shirt on open, then rope-soled espadrilles, a red lip and a canvas bag. It has that nautical beach club look you'd picture in the South of France, but it's just as much at home at the neighborhood pool.
20. Color-Block Swimsuit With Slides
Color-blocking is an old pattern-cutter's trick. Darker panels at the sides and a brighter center panel make the body look narrower without any shapewear. Diagonal color splits do the same thing at an angle. The effect only works if the panels sit where they're meant to, so check that the dark side panels line up with your actual sides and haven't twisted forward. Keep the rest plain: color-block slides, a cover-up in one of the suit colors and a sleek tote.
21. Off-The-Shoulder Swimsuit With Straw Hat
Off-the-shoulder swimwear shows the collarbone and shoulders, which is a flattering spot on most women. With a fuller bust, though, I won't consider one without a grip strip along the top edge, underwire or molded cups, and ideally a hidden clear strap. Without those, every dive or wave pulls it down. A ruched waist keeps the middle smooth. A wide-brim straw hat, lace-up flats, a rattan circle bag and pearl studs make it feel right for a garden party that ends at the pool.
22. Sweetheart Neckline One-Piece With Wedges
A sweetheart neckline curves over the bust, softening the line across a fuller chest. Underwire and molded cups do the support, and center ruching down the front adds shape. The curve can gape if the cups are too big, so try it on and lean forward; the edge should stay against your skin. I'd style it with cork wedges, a floral kimono, a lariat necklace and a top-handle straw bag. The wedges lengthen the leg, which helps at a dressier pool party or a resort dinner.
23. Twist-Front Bandeau One-Piece Swimsuit
A twist-front bandeau one-piece has no straps but much more security than a bikini bandeau, since the whole suit anchors it. The twist at the bust lets you adjust how much cleavage shows. Silicone grip tape, a detachable halter and a power mesh tummy panel are the features I check for. Detach the halter for tanning and clip it back on to swim. A high-waisted wrap skirt as a cover-up, strappy flats, square sunglasses and a bucket hat keep it clean and modern.
24. Animal Print Swimwear Set With Black Cover-Up
Animal print is easier to wear than people think, as long as everything else is black. A leopard or snakeskin one-piece with a deep V and adjustable straps, or an underwire bikini set, is the base. Put a sheer black chiffon cover-up over it, plus black wedges, a black structured tote and gold jewelry. The black around the print stops it looking loud. Medium-scale spots look richer than tiny ones, which read as busy from a distance. Wear it on holiday or to a bachelorette pool party.
25. Mesh-Panel One-Piece Swimsuit
Mesh panels at the waist, sides or neckline give the look of bare skin without actually baring it. The detail I check is what sits behind the mesh. A suit with tummy-control lining under the panel stays smooth; mesh with nothing behind it shows every curve and can leave a pattern of tan lines. A high neck or halter and full bottom coverage keep it secure. Add a linen sarong skirt, platform sandals, beaded bracelets and a leather-look bag for a beach club or an evening by the water.
26. Belted Waist Swimsuit With Tailored Cover-Up
A fabric belt or wide waistband marks the middle and creates an hourglass quickly. Pick a one-piece with ruching, a belt at the natural waist and underwire. The belt should be sewn down or have a solid buckle that won't rust; metal hardware left wet in salt water can stain the fabric. A structured short-sleeve cover-up dress in one solid color, espadrille wedges, a leather tote and a gold cuff make it smart enough for a casual lunch without changing. It suits apple, rectangle and hourglass shapes.
27. Asymmetrical Cutout Monokini With Sheer Skirt
An asymmetrical monokini with one shoulder strap and cutouts on one side pulls the eye on a diagonal, which narrows the outline. One shoulder strap carries the whole bust, so for a cup size above D I'd check that strap is wide and the built-in bra has its own structure. The cutouts should sit at the waist. A sheer printed maxi skirt worn low on the hips, heeled strappy sandals, geometric earrings and a mirrored clutch suit a sunset beach party or an evening at a resort.
28. Crochet Cover-Up Over Solid One-Piece
Crochet over a solid suit is my easiest cover-up formula. Pick a jewel-tone one-piece with a scoop neck, adjustable straps and tummy control, then add a crochet maxi dress or tunic. The open stitch shows the suit color through and lets air move, so you stay cool. Crochet stretches when wet and snags on wicker chairs, so I keep it as a dry cover-up and fold it, never hang it. Leather flat sandals, a beaded bag, layered pendants and round sunglasses suit beachfront lunches and shopping on holiday.
29. Tie-Dye Swimsuit With Distressed Denim Shorts
A tie-dye suit has a relaxed, playful feel. A scoop neck and moderate coverage in bright blue or pink tie-dye keeps it easy. Instead of a sarong, wear distressed high-waist denim shorts as the cover-up, with white sneakers, round sunglasses and a canvas backpack. Denim shorts over a damp suit can rub at the inner thigh, so let the suit dry first or pick a stretch denim. This is a boardwalk, carnival or summer festival outfit.
30. Lace-Up Front Monokini With Metallic Sandals
A lace-up front monokini combines a deep V with corset-style lacing, so you decide how much skin shows. Built-in underwire and tummy control mesh hold everything in place. Before you swim, tie the lacing tight and tuck the ends; loose ties loosen further once wet. The lacing makes a vertical line down the center, which lengthens the body. Metallic flat sandals, a sheer maxi skirt, layered chains and a high bun suit a beach party or a tropical trip.
Chlorine, Salt and Sunscreen Wear Out a Suit Fastest
A well-made suit with good underwire and power mesh costs more, so it's worth making it last. Spandex is the fiber that breaks down, and chlorine, heat and sunscreen are what break it down. Once it goes, the suit sags at the seat and the tummy panel stops doing anything.
- Rinse the suit in cool fresh water right after swimming, even if you can't wash it properly until later.
- Hand wash with a mild detergent. The washing machine bends underwire and the dryer kills elastic.
- Press the water out in a towel rather than wringing, and dry it flat in the shade.
- Sit on a towel on rough pool edges and wooden decks, which pill the seat quickly.
- If you swim often, rotate two suits so each has a full day to dry and recover.
Sunscreen can also leave yellow or rusty stains on white and pale suits, especially in hard water. Let the sunscreen sink in before you put the suit on, and save the lightest colors for days you aren't reapplying all afternoon.
Fit the Band and Torso, Then Pick the Style
Plus-size swimwear has caught up. Underwire, power mesh, ruching and adjustable straps are now standard rather than rare, and the 30 outfits here run from rashguards and boyleg suits to cutout monokinis and 1950s one-pieces. Start with fit: a firm band, a torso that's long enough and straps that don't dig in. Then choose the shape that matches how you'll spend the day, add a cover-up you can walk around in, and head for the sand or the pool deck ready to enjoy the summer.
