A mid-summer dip in the pool is wonderfully refreshing for pretty much anybody, but for expecting moms it can feel even more glorious. Raging hormones mean your body temperature can sometimes be tough to regulate and nothing relieves back pain and pressure from your ever-expanding belly better than floating in water. So, to help mamas-to-be on their quest for a comfortable summer pregnancy, we found the 17 best maternity swimsuits designed especially for you and your bump. Now all you need is a good book, a thick layer of SPF and sweet relief from anybody telling you “you look like you might pop any day now!”

What to Look for in a Maternity Swimsuit

Of course the number one thing to consider when buying swimwear is comfort, but when it comes to maternity swimwear there are a few extra notes that are important to pay attention to. According to the experts at maternity brand Seraphine the top three things to look for are “Expandability, durability, longevity!” The materials should be able to stretch alongside your growing belly without going sheer or snagging. They also suggest looking specifically for suits with ruching along the sides. “This will give you even extra room to grow and will ensure the swimsuit doesn’t constrict your waist.” As for what to avoid, they advise paying close attention to fit and the placing of seams. “If you are at the earlier stages in your pregnancy, remember that your hips and under bust will grow, so when trying on maternity swimsuits make sure to avoid styles that are tight on these areas and focus on styles that have a bit of extra room for growing. Avoid swimsuits that have seams on the bump, this can be a sensitive area. And anything with tummy-control or a restrictive fit is a no-go!” With those things in mind, here are 17 maternity swimsuits that check all our boxes.

The Best Maternity Swimsuits at a Glance

The 12 Best Maternity Leggings For Every Body and Every Budget

  • Why We Love It: Timeless design, budget-friendly price tag

Hot tip for pregnant gals on a budget: ASOS has tons of great maternity clothing, including swimwear, that won’t cost you an arm and a leg. And while there are some bright colors and bold patterns on the site, we love this classic black halter as a timeless pick you can add to cart now and wear through any and all future pregnancies. The sides of the torso feature ruching to allow the material to stretch with your baby bump, and the top has an adjustable tie in back so you can loosen or tighten it as need be. Reviews suggest it runs true to size and both looks and feels like a much more expensive suit IRL. Just know, there is no padding in the bust, so if you want a little extra coverage there, you’ll have to slot in your own cups.

Size range: 2 to 16

Best Adjustable One-Piece

2. Cache Coeur Poppy Swimsuit

Cache Coeur

  • Why We Love It: Made from eco-friendly materials, has built-in UV protection, machine washable (but the brand suggests laying it flat to dry)

Cache Coeur has lots of adorable swimsuits for new mamas, but this particular style is our favorite both for the bright, colorful print and for the adjustable straps and bust. The white shoulder straps tie in back and can be tightened or loosened as your body changes, to see you through the first trimester all the way through post-partem. Plus, the soft luxe fabric has built-in UPF50+ for extra sun protection and is made from Oeko-Tex materials, making this a more eco-friendly option for those with sustainability on the brain.

Size range: S to XXL

Best Plus-Size Suit

3. Pink Blush Waist Tie One-Piece

Pink Blush

  • Why We Love It: Adjustable waist tie and shoulder straps, double-lined

We’re not going to lie, finding plus-size maternity one-pieces is more difficult than we’d like. But there are a few brands that carry cute non-bikini options, like Pink Blush. (Motherhood Maternity and Target are two others.) For those who’d rather not bare their belly all summer, Pink Blush has five swimsuits—in more than just plain black—to choose from, but our favorite has to be this wrap design. The tie waist is fully adjustable so you can tighten or loosen it as your body changes, and the straps are also adjustable to better fit longer or shorter torsos. The cups are padded to avoid any nippy situations, and it comes in four color options—black, navy, a tropical floral print and the green above.

Size range: 1X to 3X

Most Splurge-Worthy Plus-Size Suit

4. Good American Maternity Always Fits Top and Briefs

Good American

  • Why We Love It: Can be worn long after the fourth trimester, incredibly comfortable material, goes up to a size 5XL

For those who like a more seamless look, this Good American bathing suit uses an innovative super-stretchy material in place of ruching in order to grow along with your bump. It hits a perfect balance between compression and stretch, offering support without sucking you in too much and comfort without fear of sagging or drooping. And just like everything else from the brand, this bikini comes in sizes XXS to 5XL, so even more women can feel like red-hot superstars when they hit the beach. One reviewer writes, “It’s the perfect suit for pregnancy. Not too tight around your tummy and super flattering cut. The top feels super secure too, but doesn’t make you feel like a frumpy pregnant lady. I absolutely love it!”

Best High-Waist Bikini

6. A Pea in the Pod High-Waisted Liberty Bikini

A Pea in the Pod

  • Why We Love It: Runs true to size, flattering ruching along the hips, offers plenty of coverage without feeling dowdy

A Pea in the Pod is an excellent place to shop all things pregnancy (including postpartum nursing tops and clothes for baby, too), and the brand’s swimwear has been a hit with mamas for years now. We love the gorgeous red and purple Liberty Print floral, plus the bottoms come with ruching on the side to better fit bellies of all sizes. And there is no true waist band so you won’t feel constricted or limited as you grow. As for the top, parallel straps which crisscross in the back offer plenty of bust support without looking dowdy. Truth be told, our only gripe is that you can’t buy the top and bottom in separate sizes.

Size range: XS to L

Best Tankini

6. Summer Mae Wrap Front Tankini

Summer Mae

  • Why We Love It: Budget-friendly price tag, adjustable shoulder straps and hip ties

Wiggling into a one-piece is a challenge even for non-pregnant women. But for those who prefer to keep their midsection covered, a tankini is a great way to achieve the same full coverage look without requiring a 15 minute rest break after getting dressed. This Summer Mae style comes in five gorgeous hues (including black), and has an extra-long cut to ensure your belly is covered all the way up to delivery. It comes with removable padding in the cups and the shoulder straps, which crisscross in back, are adjustable so you can lengthen or shorten them to fit your changing bustline. The bottoms also have adjustable ties on the hips for the same great customizable fit.

Size range: S to XL

  • Why We Love It: Budget-friendly price tag, available in lots of fun colors, offers full coverage without feeling dowdy

For the gal who is always on the hunt for a bold, fun ‘fit that will stand out from the sea of little black swimsuits, this adorable bikini is sure to be a hit. There are six fun color/pattern combos to choose from, all of which have the same chic smocking up top and flattering ruching along the hips. The top also has removable padding and the shoulder straps are adjustable and can be either removed entirely for a strapless look or crisscrossed in back for bonus support. Multiple reviews mention how comfortable the bottoms are and that they don’t seem to pinch or dig in around the legs, even come the third trimester. It appears it also runs true to size and may even work well for those with longer torsos. Per one reviewer, “This is a super comfortable bathing suit and very cute. The material is nice and doesn't cut you in any weird places. I'm eight months pregnant and decided to size up to an XL after reading reviews, but I would suggest ordering true to size. It's plenty long for tall girls, gives adequate breast support (38DDD) and plenty of belly room and growth space.”

Size range: S to XL

Trendiest Silhouette

8. Cache Coeur One-Shoulder One-Piece

Cache Coeur

  • Why We Love It: Comes with an additional shoulder strap for bonus support, available in five chic colors, UPF 50+ sun protection built-in

One-shoulder swimwear has been growing in popularity for the past few summers as a more modern alternative to most classic silhouettes, but that doesn’t feel like a flash in the pan fad. This cute maternity suit fits right in with the trend and is also made from Oeko-Tex materials, for an eco-friendly boost. The material also has built-in UPF 50 sun protection. The sides have that belly-friendly ruching we so love, and there is a built-in shelf bra for additional bust support. “One of my absolute favorite suits,” raves one reviewer. “Perfectly form fitting, not tight on the legs, great material!”

Size range: S to XXL

Best Little Black Swimsuit

9. Hatch the Antigua Maillot


  • Why We Love It: Timeless design, made from recycled materials, adjustable and convertible straps at the back

In the same way that you can never go wrong with a little black dress, a little black swimsuit will always be in style. This Hatch style is a perfect blend of sexy and demure, trendy and timeless, and can even be worn multiple ways thanks to the convertible straps. Wear them straight, crisscrossed or even tied as a halter to switch things up. The sides also have that great ruching we keep hitting on, and there is a built-in shelf bra for bonus support at the bust. And the ruffle adds just enough of a fun flair to make a plain black suit feel not quite so plain. “I’ve purchased an unreasonable number of swimsuits during pregnancy,” writes one reviewer. “This one is far and away the best. The material is soft, and the construction makes me feel supported. It’s very flattering and feels flirty yet mama appropriate while chasing a toddler.”

Size range: XS to XL

Best Full-Coverage Suit

10. Paula Swimwear Square-Neck One-Piece

Paula Swimwear

  • Why We Love It: Thick shoulder straps offer extra support, can be worn long after the fourth trimester

Full disclosure, this is not a maternity-specific swimsuit. But it does come recommended by at least two PureWow editors who wore it both during and after their pregnancies. “The material is just the right amount of stretchy to be supportive and comfortable,” Ali Fox, senior director of strategic partnerships, tells us. “And even though it doesn’t have a shelf bra, it has great bust support.” Indeed, the combination of the wide shoulder straps and the proprietary Lycra-blend fabric means this suit has plenty of support for both your chest and your bump, and can be worn long after you’ve given birth (which is something to consider given the higher price point). The back also offers plenty of coverage, with a higher cut back and full seat.

Size range: S to XL

Best for Swim Workouts

11. EQ Swimwear Maternity Tankini

EQ Swimwear

  • Why We Love It: Built-in shelf bra, drawcord waist prevents the top from riding up

We looked at multiple bump-friendly workout one-pieces, but ultimately decided this tankini was the better choice for one important reason: It’s much easier to put on and to take off when you need a bathroom break. According to reviews, the top doesn’t ride up during laps thanks to a hidden draw cord that can cinch under your belly. The racerback offers lots of bust support, aided by a built-in shelf bra, and allows for full range of motion. A few reviewers also mentioned how much they appreciated the higher neck, which offers a bit more coverage, so you don’t have to worry about your cleavage while you run around the beach or pool. “I debated a lot about what kind of suit to buy,” writes one reviewer, “I have been a competitive swimmer and triathlete for years and I wanted to continue swimming through pregnancy. I got the size small, typically I am a medium on top and there’s plenty of room for my growing belly. All in all, I’m very happy with my purchase.”

Size range: S to XL

Best Rash Guard

12. Seraphine Maternity Rash Guard


  • Why We Love It: Built-in UPF 50 sun protection, hidden shelf bra, machine washable (although the brand recommends you lay flat to dry)

Whether you’re planning on an active beach day or simply want some extra coverage from the sun, Seraphine has you covered—literally. This cute floral rash guard has ruching along the sides to accommodate your growing bump and is made from recycled nylon with built-in UPF 50 to block even more UV rays. The half-zip at the bust is longer than your typical rash guard, making it easy for you to breastfeed without having to take your whole top off. And the coordinating bottoms can be worn either as a high-waist style or folded down if you prefer a lower rise.

Size range: XS to XXL

Best Swim Shorts

13. Kindred Bravely Swim Shorts

Kindred Bravely

  • Why We Love It: Hidden side pockets, built-in UPF 50 sun protection, machine washable

Yes, you could wear a pair of waterproof shorts over a bathing suit bottom you already own, but these maternity swim shorts do both, eliminating any awkward bunching or tugging that might come from DIY layering. They have a slim-fit inner lining and a lightweight, looser outer layer to give you the comfort of bike shorts but the look of regular workout shorts. There’s also a pocket on the left leg of the inner shorts large enough to fit your phone (yes, even in a bulky waterproof case) or anything else you just have to have on hand at the beach. They can be worn as a regular workout short for running, yoga or weightlifting at the gym in additional to swimming laps. And according to reviews, they run true to size.

Size range: S to XXL

Best for Nursing

14. Moloco Jojo Bikini Top


  • Why We Love It: Available in 11 chic color options, has UPF 50+ built in sun protection, machine washable (although the brand suggests laying it flat to dry)

In the same way that pregnancy should never stop you from doing the things you love (i.e., taking a dip or hanging by the pool), neither should breastfeeding. This relatively new, but beloved, brand is all about creating nursing-friendly swimwear that is also chic and supportive, with the Jojo top being one of its absolute best sellers. The innovative wrap design allows you to expose your nipple for feeding without having to expose your entire breast, and is also highly adjustable for a better fit whether you’re actively breastfeeding, pregnant or just adjusting to your new mom bod. “I have lived in the Jojo top, paired with the Coco bottoms, for the past week and have nothing but amazing things to say about it,” writes one happy shopper. “The material is incredibly soft and comfortable. The fit is great. I followed the sizing recommendations and found them to be spot on, and the coverage of the top was fantastic. I felt sexy but also wasn't worried about falling out. And of course, nursing in this top was a huge success! Highly recommend.”

Size range: XS to XL

Editor Favorite

15. Summersalt the Maternity Cinched Current


  • Why We Love It: Adjustable ties at the hips and bust, has a built-in shelf bra, offers full coverage in the rear

Summersalt has long been one of our favorite places to pick up incredibly flattering, well-made swimwear that won’t break the bank. And while the brand doesn’t have many maternity styles (there is currently one one-piece and one bikini, each available in just two colors), they are just as luxurious-feeling and well-fitting as the brand’s non-pregnancy suits. We love that the Cinched Current swimsuit has adjustable straps which cross at the back, and that the material is a bit thicker to offer more support in the areas where you want it most. There are also adjustable pulls at the hips to ensure you find that Goldilocks fit for your torso length and belly size.

Size range: 2 to 14

Reader Recommended

16. GAP Ruffled One-Piece


  • Why We Love It: Adjustable ties in back, machine washable, strategic seaming under the bust offers extra support

This cute GAP one-piece came recommended to us from multiple PureWow readers for two main reasons—there are a bunch of fun prints to choose from, and the top fits impeccably on a range of different body types. In addition to the vibrant Barbie pink above, this suit also comes in silicate purple, classic black, leopard spots, a black-and-white floral and a bright neon floral. And while some reviewers found themselves sizing up to better fit their bums/thighs, everyone agreed that the top was incredibly comfortable and supportive thanks to the trio of built-in padding, adjustable straps and a tie at the back for bonus support that’s also chic. It’s also made from more than 90 percent recycled materials for an eco-friendly boost.

Size range: XS to XXL

Best Non-Maternity Maternity Swimsuit

17. Youswim Aplomb One-Piece


  • Why We Love It: Available in tons of fun colors, incredibly comfortable, can be worn long after the fourth trimester

OK, so this Youswim bestseller is not, in fact, a maternity-specific design. However, the fabric is super stretchy and can adjust to fit your changing body at every stage of pregnancy and even into the fourth trimester and beyond. In fact, this one-piece comes in just one size, with the promise that the brand’s signature material will stretch to fit sizes 2 through 14 without becoming sheer or digging in. The only caveat is that the material isn’t super supportive and there is no internal structure to speak of (i.e., no cups or shelf bra). But as one new mom and PureWow editor told us, “This suit is just so comfortable. It was a dream being able to pull it on without any struggle or jumping or tugging so I could just focus on relaxing by the water and enjoying myself.” In fact, she loved that unbeatable comfort so much, she bought this suit in three colors—and in turn inspired two other PureWow mamas to try the brand for themselves.

Size range: One size fits most (fits approximately sizes 2 to 14)
