The 34 Best One-Piece Swimsuits for Women of 2024

One-piece swimsuits are chic, comfortable, and reliable — like a fabulous longtime friend, they can offer support, build up your confidence, and even convince you to go on vacation.

"You want a suit that not only fits great but makes you feel great," says Olympic swimmer and silver medalist Emma Weyant, adding that comfort, flexibility, and durability are also essential. Celebrities also return to this swimsuit style consistently, so if you haven't yet found your favorite, we're here to help.

We tested one-piece swimsuits in pools, oceans, and showers, taking note of the fit, comfort, quality, performance, and value. We also gathered editor-loved favorites, scoured the internet for new styles from reliable brands, and engaged with experts like Joanna Lovering, an NYC personal stylist and empowerment coach. She encourages folks to embrace their body and she gave PEOPLE suggestions based on her clients' feedback regarding confidence and comfort in a one-piece swimsuit.

 Read on for the best one-piece swimsuits for women of 2024.

Best Overall One-Piece Swimsuits

Best Tummy Control: Mindy x Andie The Amalfi

Mindy Kaling collaborated with Andie on a swimwear collection, and when we asked about her favorite piece, she praised The Amalfi suit. “There is a daffodil-colored one-piece — and I know that not everyone feels comfortable wearing a yellow bathing suit — but it is the most flattering cut.” (Psst: It comes in nine other colors!)

Kaling’s favorite swimsuit is also our PEOPLE Tested top pick for a one-piece swimsuit. Our tester loved its secure, comfortable fit, reporting that the suit stayed in place while going down water slides at the water park and playing water sports in the pool with her kids. She has the suit’s adjustable straps, underbust elastic, and sculpting fabric to thank for that.

Size Range: X–XXXL | Materials: Nylon, Spandex | Colors: 10

Best Underwire: Panache Anya Riva Underwire One-Piece

This one-piece from Panache provided the best bust support in our tests. We’re fans of the double-layered balconette cups that come in larger sizes traditional swimsuit makers don’t always cater to. Throughout testing, this suit kept us supported and secure while walking and swimming. 

The adjustable straps and snap-back closure offer even more comfort while supporting your curves. The fabric is soft but durable and kept its shape after we wrung out the water during testing. A tummy control panel is another flattering feature we love about this suit’s design

Size Range: 30-40; D-K cups | Materials: Polyamide, Elastane | Colors: 2

Best Cheeky: Cupshe Criss-Cross One-Piece

In our view, it’s clear that celebrities want the same coverage and comfort out of a one-piece swimsuit that we do. This Cupshe criss-cross one-piece is a dead ringer for the one Salma Hayek was spotted in last year, and it effectively shuts down the antiquated notion that one-piece bathing suits are modest and frumpy. 

The super cheeky cut has minimal butt coverage to highlight and elongate the legs. The plunging sweetheart neckline highlights the bust, and the rose red color is a solid dupe for Hayek’s magenta number. (This suit also comes in six other great color options.)  

Size Range: XS–XL | Materials: Nylon, Spandex | Colors: 7

Best Cut-Out: Eomenie High Waisted One-Piece

This best-selling suit has over 7,700 five-star ratings on Amazon, and with features like tummy control and push-up pads, it’s easy to see why. It comes in vibrant colors like wine red, black stripe, and leopard print. One reviewer said it has helped her feel “confident in her mom bod.” We didn't test this one ourselves, but it’s a perennial best-seller on Amazon, so we feel confident recommending it.

Size Range: XS-22 Plus | Materials: Nylon, Spandex | Colors: 32

Best Plus Size: Nomad Coast One-Piece II

Lovering is a fan of this size-inclusive, Black- and women-owned small brand, and now we’re fans of this one-shoulder suit with eye-catching sheer power-mesh panels that provide high-impact support. A thin rubber strip at the top of the suit secures it in place, and the double-lined seamless leg openings won’t dig into skin. This suit comes in gorgeous neon colors, as well as chic and subtle prints.

Size Range: XS-5X | Materials: Nylon, Spandex, Recycled Polyester | Colors: 9

Best with Shorts: BeautyIns One-Piece Boy Shorts Swimsuit

Paging Sporty Spice. One of several swimsuits we love at Amazon, this athletic boy-short swimsuit provides ample coverage and stays in place; an ideal quality for water sports and exercise. The racerback top is supportive, and the trim gives the look of an hourglass shape. The swimsuit is breathable, lightweight, and versatile; it doubles as a cute athleisure look.

Size Range: S–XXXL | Materials: Nylon, Polyester, Spandex | Colors: 28

Tummy Control One-Piece Swimsuits

Spanx Pique Shaping Plunge One-Piece

Spanx brings its shapewear roots to the Pique Shaping Plunge One-Piece. Don’t let the word “plunge” scare you: This silhouette is timeless and chic. The pique-textured fabric (a durable cross-knit cotton) is worth every penny because it’s seamless and supportive.

This Spanx bathing suit highlights your figure without showing too much skin. It’s perfect for a fun girls’ weekend and also a great family-friendly option for running after little ones by the pool. The legs and straps are dig-free for ultimate comfort, and we always appreciate the confidence boost we get when wearing Spanx.

Size Range: XS-3X | Materials: Nylon, Elastane | Colors: 3

Hilor One-Piece Front Twist Bathing Suit

During testing, we just could not get over the comfortable design of this one-piece swimsuit! After our tester swam laps, she noted that the ruched bathing suit stayed in place and provided great coverage with a lightweight yet controlled feel. The sweetheart neckline complements your chest, while the sculpting fabric around the stomach area cinches your waist. We think this swimsuit is a great deal at under $40 — because despite that low price tag, it feels high quality.

Size Range: 6-18 | Materials: Nylon, Spandex | Colors: 11

J.Crew Ruched One-Shoulder One Piece

Wearing a swimsuit can be daunting for anyone — the fitted and normally shiny fabric can highlight every little bump, roll, and dimple on your body. That's why we love the ruching effect on this one-piece swimsuit from J.Crew: It's an optical illusion of sorts that becomes the star of the show, helping to smooth out your tummy area. Plus, the one-shoulder design is so cute!

Size Range: 0-24 | Materials: 82% recycled nylon, 18% elastane | Colors: 11

Cupshe Ruffled One-Piece Swimsuit

The 3,500+ reviewers on Amazon who rated this swimsuit five stars have to be on to something. Buyers rave about how confident this Cupshe ruffled one-piece makes them feel. Folks call out its slimming and flattering features, like ruching throughout the torso and a compressive fit that offers coverage and core control. The ruffles and deep V-neck silhouette give the perfect mix of feminine and sexy, and the adjustable tie back allows for a custom fit. 

This suit comes in 23 colors and prints, and at less than $35, you might want to grab more than one.

Size Range: XS-XXL | Materials: Chinlon, Spandex | Colors: 23

TA3 Swim Plungey

TA3 Swim’s Plungey One-Piece is an internet favorite that our contributing writer promises is worth the investment. Featuring TA3’s signature shaping panels and lacing, the unique lace-up back snatches your waist, giving an hourglass appearance. The midweight compression fabric offers support and keeps everything in place. 

We love how the plunging neckline is offset by a lower-cut leg and full bottom coverage. With a wide size range to shop from, we think this suit will make everyone look and feel great.

Size Range: XXS–4X; Short, Regular, X-Long Torso | Materials: Nylon, Spandex | Colors: 14

Kona Sol Full Coverage Tummy Control High Neck Halter One Piece

Target does it again! We love the design of this halter one-piece swimsuit. The high neck and full bottom coverage are balanced out by the key-hole cutout. You can adjust the  around-the-neck ties for a custom and comfy fit. The supportive spandex and ruching design is ideal for those who prioritize tummy control. It also comes in a deep teal color.

Size Range: XS-XL | Materials: Nylon, Spandex | Colors: 1

Onewith Bellows Plunge High-Cut One Piece

One of our editors swears by this swimsuit. The plunging neckline and cheeky backside bare plenty of skin so there’s no need to debate over whether it’s a “bikini day” or not, and the material is super sculpting, so it keeps everything lifted and compressed. It looks like shapewear, which is great because it can double as a bodysuit when paired with jean shorts or a maxi skirt.

Size Range: XXS-4XL | Materials: Nylon, Elastane | Colors: 1

Underwire One-Piece Swimsuits

Firpearl Underwire One Piece Swimsuit

This underwire one-piece from Firpearl is an affordable swimsuit that offers bust support without  compromising on style. The V-neck design and twist detailing accentuates your chest, while the hidden underwire keeps it lifted. 

We appreciate the ruching detail at the waist and how the adjustable straps allow for a seamless fit and ample support. Plus, the higher back and moderate bottom coverage make it a more modest option than some of our underwire picks. For under $40, you can’t go wrong with this one.

Size Range: 6-16 | Materials: Polyamide, Spandex | Colors: 3

TA3 Swim Lifty Swimsuit

The Lifty one-piece not only creates a signature hourglass figure, but also lifts and supports your bust since it uses actual cups (rather than bust pads). We also love the thick supportive straps that hold you up without digging into your shoulders. 

It’s more structured than the TA3 Plungey Swimsuit, but uses the same compression fabric to cinch in your waist. This one can accommodate larger busts, as cup sizes go up to K. The sizing at TA3 is super inclusive, and this suit comes in a variety of torso lengths as well. 

Size Range: XS-4X | Torso: Short, Regular, XLong | Cup Sizes: A–K | Materials: Nylon, Spandex | Colors: 6

Cupshe Blooming Party Ruffled Underwire One-Piece

Bust support never looked so fun! This ruffled underwire one-piece from Cupshe features a vibrant floral print that’ll be a magnet for compliments. The bowties and ruffles add a soft feminine feel that balances out a subtly sexy one-piece. A cheeky high-leg cut offers moderate bum coverage and offsets the pattern’s cottagecore aesthetic. 

The molded cups with removable pads are supportive, and the fabric’s light metallic sheen sparkles in the sunlight.

Size Range: XS-XL | Materials: Polyester, Metallic, Spandex | Colors: 2

Shade & Shore Twist Underwire Cheeky One-Piece

This one-piece from Shade and Shore has a fun twist detail that camouflages the underwire, as well as adjustable straps for a customized and supportive fit up top. We like how the cutouts on the front and back show off a bit of skin. Further taking this one-piece out of the realm of “modest” is its cheeky (read: side butt-baring) backside and high-cut design that’ll give you legs for days. Shop it in classic black, bright red, and sage green. 

Size Range: 32 B, 34 B-DD, 36 B-DD, 38 D-DD | Materials: Nylon, Spandex | Colors: 3

Cheeky One-Piece Swimsuits

Andie Fiji One-Piece

The Andie Fiji One-Piece is our top pick for a fun, cheeky suit. Its high cut shows off and elongates your legs, while a low-cut, lace-up back shows off what’s right above them. You can adjust the fit depending on how you tie the wrap-around straps. We love how the sexy back is balanced by a front that’s chic and simple.

Size Range: XS-XXXL | Materials: Recycled Nylon, Spandex | Colors: Black, Cherry Red

Aerie Crinkle Birthday Scoop Cheekiest One Piece Swimsuit

This fashionable one-piece is equal parts trendy, sleek, and even a little bit sexy (though it's still fairly modest). The crinkle fabric is a fun textural feature and its open-back design is a cute way to show a little skin. Its slightly daring front looks ultra-flattering on all body types thanks to its high leg cut. 

Because this one-piece is so stylish, it'll be easy to throw a pair of cover-up pants on top or slip into a long maxi skirt to make an outfit that can go from beach to surf bar.

Sizes: XXS–XXL | Materials: 96% recycled polyester, 4% elastane | Care: Hand wash, air dry | Colors: 3

Summersalt x Mestiza Ruffle Backflip

Joanna Lovering recommends this Summersalt one-piece for pear-shaped humans. The ruffle sleeves and deep V plunge bring more focus to your upper body, while the cheeky bottom shows off your curves and elongates your legs. The unique low square back truly makes this Summersalt one-piece a showstopper. Plus, Summersalt’s high-quality and compressive fabric keeps everything in place. 

Size Range: 2-22 | Materials: Recycled Polyamide, Elastane | Colors: 6

Aerie Sparkle Pique Babewatch One-Piece

The name says it all. This Aerie swimsuit will have you channeling your inner lifeguard and running in slow motion on the sand. We tried this suit ourselves and can’t get over how it feels. It’s the perfect combination of stretchy and soft, and the thick straps are supportive and comfortable. The scoop neckline, low back, and cheeky bottom hit in all the right places for an extreme confidence boost.

Size Range: XXS-XXL | Materials: Recycled Nylon, Nylon, Elastane, Metallic | Colors: 1

Sporti x Emma Weyant Riviera Microback One-Piece

Gone are the days of boring athletic swimwear. The Emma Weyant x Sporti collab is a match made in swimsuit heaven. Featuring stretchy and compressive chafe-proof fabric, this suit is meant for the serious swimmer. (Serious or not, we love this flattering cut-out open back and cheeky high-cut leg.) Featuring durable chlorine-proof fabric, this suit, and its vibrant print, will last for many swim sessions to come. Having tried this one ourselves, we can say that it absolutely stays in place while swimming laps.

Size Range: 26-40 | Materials: Recycled Polyester, PBT Polyester | Colors: 4

Cut-Out One-Piece Swimsuits

Tempt Me Cutout Tie-Knot One-Piece Swimsuit

This one-piece has a below-bust cut-out and a retro high waist. Ruching throughout the stomach area offers some coverage. And the neck-tie straps are removable and can convert it from a halter to a strapless design. We also love that it has vibrant colors and plus sizes.

Size Range: XXS-XXL, 18 Plus-24 Plus | Materials: Nylon, Spandex | Colors: 39

Cupshe Cutout Scallop Trim One-Piece Swimsuit

There's so much to love when it comes to Cupshe Swim styles. The scalloped trim on this Cupshe cutout one-piece is a unique take on this style of swimsuit. It shows more skin than a typical one-piece, yet offers more coverage than a traditional bikini. The scalloped edges won’t dig into your skin, and the adjustable straps offer an adjustable fit.

Size Range: XS-XXL | Materials: Polyester, Spandex | Colors: 4

Holipick High Neck Cutout One-Piece Swimsuit

This high-neck one-piece is a lookalike for Dakota Johnson’s white swimsuit. We love how the subtle side and back cutouts on the otherwise modest design creates the illusion of a more narrow waistline. If classic white isn’t your jam, this suit comes in colors like black floral and hot pink, too.  

Size Range: XXS-XXL, 18 Plus | Materials: Nylon, Spandex | Colors: 28

Aerie Wide Rib Cut Out Ring One-Piece Swimsuit

This swimsuit is for those who aren’t afraid to show a little skin. The back looks like a traditional bikini, while the front has a ring detail, deep V-neck, and side cut-outs. Fuller bottom coverage balances out these features. The wide ribbed texture makes this swimsuit really stand out.

Size Range: XXS-XXL, XL Long, XXL Long | Materials: Recycled Nylon, Elastane | Colors: 3

Plus Size One-Piece Swimsuits

Summersalt The Perfect Wrap One-Piece

Our team has worn many Summersalt one-pieces throughout the years, and we love the style and durability this brand offers. The flattering wrap design of this suit will hug you in all the right places and accentuate your waist. Featuring Summersalt’s signature compressive fabric, this one-piece will keep you secure while you’re in the waves. It comes in 13 eye-catching colorways and patterns — we’re fans of this Hibiscus & Grapefruit combo.

Size Range: 2-22 | Materials: Recycled Polyamide, Elastane | Colors: 9

Dacy Vintage Ruched Bathing Suit

With an appealing sweetheart neckline, shirring throughout the torso, and a tummy control panel this vintage-inspired one-piece flatters from all angles. The built-in wireless bra provides major bust support and feels secure. The thick wide straps are comfortable, and the back clasp closure adds even more support. With full bottom coverage, this suit stays in place while you’re on the go.

Size Range: M-XL, 16 Plus–28 Plus | Materials: Nylon, Spandex | Colors: 30

Torrid Wireless Triangle One-Piece Swimsuit

The Wireless Triangle One-Piece from Torrid has a super smooth and modern silhouette — no shirring or ruching here. Instead, the power mesh panel offers tummy control and shaping. The deep wrap V-neckline is supported by thick and adjustable criss-cross straps. In terms of colors, it’s available in timeless black, Barbie pink, and a Palms Springs-esque stripe.

Size Range: 10-30 | Materials: Nylon Spandex | Colors: 3

Yonique Plus Size One-Piece Swimsuit

This suit’s criss-cross deep V-neck silhouette shows off some skin, while its thick, adjustable straps and high-cut back ensure you’ve got support. The compressive fabric holds you in, and the moderate bottom coverage stays in place. Ruching over the stomach area adds some tummy coverage as well.

Size Range: Medium, 12 Plus-30 Plus | Materials: Nylon, Spandex | Colors: 34

One-Piece Swimsuits with Shorts

American Trends Retro One-Piece With Shorts

This pretty swimsuit offers fuller bottom coverage without compromising on aesthetics. The halter strap and sweetheart neckline are a playful nod to vintage bathing suits, and the shorts are great for exercise, including running after kids on the sand. Ruching in the middle serves to accentuate an hourglass figure and provide some tummy coverage. 

Among the variety of solid colors and prints, we love the boldest pattern options, like the floral and animal print, that lean into the retro vibe.

Size Range: 4-20 | Materials: Polyamide, Elastane | Colors: 18

Fixmatti One-Piece Sport Swimsuit

This suit is somewhere between a romper and a tennis dress… but you can swim in it? Its form-fitting top looks like a traditional one-piece and features a small cut-out above the belly button; the bottom mimics a breezy athletic short with fuller coverage. It has adjustable straps and comes in bright colors like blue, orange, and pink, as well as black and white.

Size Range: S–XL | Materials: Viscose, Nylon | Colors: 5

MakeMeChic Colorblock Zip-up Swimsuit

This one’s for the water sports enthusiasts. The MakeMeChic Zip-up Swimsuit offers full coverage and support for more intense activities like windsurfing, jet skiing, and more. The mid-thigh shorts are super flattering, while the short-sleeved rashguard top will keep you protected from wind, sun, and waves.

Size Range: S–XL | Materials: Polyester, Elastane | Colors: 9

Aqua Green High Neck Swim Romper

Swim? In a romper? Yes, folks. We love this romper from Target that offers full bottom coverage and ultimate comfort. It comes in black and hot pink, both of which have a a small keyhole cutout and UPF 50 fabric. Oh, and did we mention that the shorts have pockets?

Size Range: S-XL | Materials: Polyester, Spandex | Colors: 2

What to Know About One-Piece Swimsuits

Fit

Above all else, your one-piece needs to feel snug and comfortable. Whether you’re exercising in the pool, playing water games with the family, or lounging on the beach, you want it to stay in place. To achieve this, look for materials that compress and stretch, like nylon and spandex. Always check the brand’s specific sizing guide, and if you are between sizes, look for suits with adjustable straps and other details that offer a more customized fit. When in doubt, size up. Some suits even come in various lengths for long and short torsos.

Activity or Purpose

When shopping for your one-piece, think about what purpose it’ll serve. Are you lounging poolside, walking on the beach in your beach cover-up, or swimming laps? “For training and athletic wear, I always choose a tighter, more compressed fit, while for lounging and beach wear, I go for more of a comfortable, relaxed fit,” says Weyant. Certain suits, like Weyant’s Micro Back One-Piece, are designed with chlorine-resistant fabric specifically for swimmers. If you're just looking to lounge poolside, an affordable pick like this Aerie one-piece may be all you need. If you want to do it all (swim, lounge, and keep up with the kids), The Amalfi won't let you down.

Style

Weyant thinks finding a one-piece “that makes you feel confident every time you put it on” is key. So think about what you want to accentuate: Show off your legs in the Cupshe Criss Cross One-Piece, or highlight your waist in the Eomenie High Waisted One-Piece. Whether it's a bikini, a swim dress, or something in between, the best bathing suit is the one that makes you feel great in your own skin.

Price

The pricing of one-piece swimsuits varies greatly. Our picks range from $20 to $200 — it’s just a matter of personal preference. Maybe you want to invest in one high-quality piece, or maybe you need a beach wardrobe with several affordable suits. You may also want to spend more on a suit with certain features like tummy control, power mesh panels, or actual cups for better bust support.

Frequently Asked Questions

How do I know what size one-piece swimsuit to buy?

Swimsuit brands often include a size guide that details the specific measurements for each size, but it will require you to take your own measurements. By taking your own bust, waist, and hip measurements, you can compare with the brand’s sizing guide to find the appropriate fit. As you're shopping around places to buy swimsuits, it’s a good idea to do this for each brand, as sizing can differ by brand.

What one-piece swimsuit is in style for 2024?

One-piece bathing suits that feature high-cut legs and cheeky bottoms are in for 2024, such as the Summersalt Ruffle Backflip. Other trends include details like fringe, belts, and textured fabric, like the Cupshe Cutout Scallop Trim One-Piece.

Where are the best places to buy one-piece swimsuits?

Major retailers like Target and Amazon are popular places to buy swimsuits thanks to their affordability and flexible return policies. Online brands like Summersalt and Andie are also popular options. They both offer extensive sizing, fit guides, and customer reviews to help guide the buying process.

Take Our Word For It

L.A Hubilla is a freelance commerce writer for PEOPLE and newly converted one-piece lover. For this article, she consulted Olympic silver medalist swimmer (and swimsuit designer) Emma Weyant on one-piece features shoppers should consider. She fielded suggestions on bathing suit styles for varying body types from personal stylist and empowerment coach Joanna Lovering, whose clients are worldwide, mainly in Fortune 500 companies, and defy all age, gender, and body shape stereotypes.

This piece was updated by Erin Johnson, associate editorial director at PEOPLE. Erin consulted testing insights from a recent PEOPLE Tested swimsuit test and added additional options to this piece. To test one-piece swimsuits, our testers showered in the suits, timed how long it took them to dry, and then wore the bathing suits to the pool, beach, or whatever water activity area was available to them. They evaluated the suits' fit, comfort, quality, performance, and value. Top-scoring one-piece bathing suits were added to this list.
