Summer is upon us, and that means it’s time to start shopping for the best maternity swimsuits of the year. Whether you are early in your pregnancy or getting close to bb’s arrival, you’ll definitely need a comfortable maternity swimming suit in your arsenal (and a due date calculator, mama because time really does fly). And just like with jeans, and maternity bras, you need actual maternity products. Your favorite swimsuit is just not going to cut it as the bump starts to grow. Show off whatever stage you’re in, even if you’re just letting everyone know there’s going to be a baby! Once you pass month 4 or 5, your fashionable bump will become your main attraction.

Can you wear a regular swimsuit while pregnant?

Of course you can, but there are some pretty big differences in normal swimsuits versus maternity swimsuits. Swimsuits for pregnancy are made with stretchier materials, they have a softer belly,  and the sizing is more likely to be correct. If you purchase a normal swimsuit, be sure to size up to ensure extra comfort. Fashion swimsuits that are not made specifically for pregnant women often have designs like cross straps, hooks, etc. As a woman with a very small bladder at the moment, that’s something you *don’t* want to deal with. Another reason why maternity swimsuits are the perfect option when pregnant: they’re made just for you, Mama!

Below, you’ll find high-quality online maternity bathing suits that are stretchy in all the right places, and stylish to boot. We’re talking pretty patterns, trendy cuts, maternity tankinis, maternity one piece suits, and yes, even a few maternity bikini sets to flaunt that gorgeous belly of yours. Because every mama-to-be needs a comfortable poolside pregnancy bathing suit to wear when lounging like it’s her J-O-B. Well deserved.

Best Maternity Swimsuits

A Pea In the Pod Splendid One Piece Maternity Swimsuit

A little bit nautical with a whole lot of style. This striped maternity one piece is made by one of our favorite tee shirt brands so you know it has to be comfortable. We love how the stripes make a sort of chevron pattern over the belly for a more flattering style. And it comes in two colors: a more subtle blue and white stripe or a bolder nautical stripe with different shades of blue. One happy mama-to-be said: “I am 100% in love with this swimsuit. It has great coverage, stretches in all the right places and is crazy soft but also dries fast. The material isn’t clingy, it’s soft and breathable. My growing belly was dripping with sweat in other suits and tankinis but not with this one!”


PinkBlush Maternity Black Ribbed Ruffle Trim Bikini Maternity Set

Why not go with an option that you would actually wear IRL but that’s made for your adorable (and growing) bump? This pregnancy bathing suit is double lined for coverage and features a sweet ruffle trim and an adjustable tie-back closure to keep everything in place. Elastic bikini bottoms with adjustable ties will grow with you and BB and will last well past baby’s arrival. 


EastElegant Maternity One Piece Halter Swimsuit

This is a fan favorite on Amazon; it comes in 10 colors from rich solids to tropical floral prints so there’s something for every mama-to-be. Padded cups, adjustable shoulder straps, and ruched sides help keep preggos comfy and accommodate growing bods. Expectant reviewers have praised its comfort and coverage, including one who noted “This is so cute! I put this on and it fit perfectly. I ordered a large and am currently 24 weeks. The fabric is super stretchy so I’m confident it will work for the rest of the pregnancy. I’m normally a 36dd so finding tops to fit is usually hard without the girls gushing over the sides but this fit in the top so perfectly, the elastic top band is slightly big in the back but nothing to really notice especially because I know I’ll only get bigger! This also fit great to cover the butt. I’m normally 160lbs pre-pregnancy and a large fit everywhere that grew the last 30lbs I’ve put on.”

Cache Coeur Kyoto One-Piece Maternity Swimsuit

Simple. Chic. Comfy. What else could you want, Mama? This one piece suit comes in both navy and pink, each with the gorgeous scallop trim details on the neckline and the back. It has built in UPF 50+ sun protection (you know we love that!) and easy ties in the back. The best part about this swimsuit is that there’s a built-in bra that provides comfy support ALL day!


Prego Maternity Bikini With Halter Top

This review says it all: “It fits perfect and covers everything that my pre-pregnancy bikini doesn’t cover anymore. I am usually a size small and at 30wks I wore this bikini in Medium and it fit great. I am sure it will last through my whole pregnancy. Also, very comfy and didn’t pinch at all.” But in case you want to know more…. It is made in the US, features adjustable, roll waist bottoms that can be rolled up for more coverage or rolled down for support. There are removable soft cups and the halter top is adjustable with a back hook closure and can be adjusted in the front as well with a tie. It comes in 2 color options: blue for a beachy look or black with polka dots for a classic vibe. It’s a sweet but also sporty pick.


ASOS DESIGN Maternity Ruhed Tie Front Swimsuit

Stylish. Classy. Adorable. We love this bold colored maternity swimming suit from ASOS. It’s understated but also very fashionable. The tie-front neckline and ruched sides are flattering and unique, unlike all those #basic pregnancy swimsuits. (It’s also super easy to get out of!) Adjustable straps help to make sure it’s the right fit, plus they’ll grow with your changing belly and body. And we think this will carry you well into the newborn days for a comfy but put-together look. It keeps you feeling stylish even when you feel like your expanding belly is taking center stage.

Kindred Bravely Crossover Nursing & Maternity Bikini Top

Looking for something that’ll work post partum too? This Maternity Bikini Top from Kindred Bravely is made to make nursing easy and convenient. For comfort and support, the straps are thick and adjustable. And on top of it all, how cute is the pink color? Don’t forget to grab the matching bottoms too!


Tempotrek Maternity Swimsuit One Piece

This pick is classic with just the right amount of attitude. The wrap design is great for a changing body (and growing baby belly). And the yellow stripes add a sweet feminine detail that can’t be beat.  The ruching on the sides makes the already flattering cut even better… and more comfortable! It’s basically a no-brainer if you’re looking for a flattering one-piece wrap maternity swimming suit. This style is so classic, you’ll re-wear this with bb #2, or #3, or…you get’ll be able to wear this for a long time to come.

MiYang Off the Shoulder Maternity One-Piece Swimsuit

There’s no reason why you can’t feel cute when you’re rocking an Amazon maternity swimsuit. This floral maternity one-piece swimsuit has a pretty off-shoulder style with ruffles. The ruched sides will flatter your growing belly. Our favorite feature? Shoulder straps that are adjustable and removable so you can wear it in 2 different styles. The double-lined construction is perfectly stretchy and supportive at the same time. Reviews say that is a great/supportive find for ladies with a bigger bust size. And it comes in 10 other fun prints, with everything from cute lemon prints to solid options and other tropical-inspired patterns. At this price range, it’s definitely worth grabbing more than one.

Summer Mae Maternity V Neck Swimsuit

Whoever said ruffles on a swimsuit was too much was obviously never pregnant. Sometimes we need a little flair to shine and this Summer Mae maternity swimsuit does just that. Featuring a smooth weave, it feels great on and has a trendy v-neck cut with those fabulous ruffles. The black color keeps the look minimal but also edgy, and we love it also in a navy, green, and blue floral pattern. Shirring at the sides also makes things comfortable and flattering for the mama-to-be. And it lasts throughout the entire pregnancy (and after!). The ruched material makes sure of it. One reviewer says: “I am very happy with this maternity swimsuit, comfortable, quality was great, lined with removable breast pads is a plus too!”

PinkBlush Beige Cheetah Print One-Piece Maternity Swimsuit

Cheetah is the ultimate vacation print and it’s never going out of style, mama. This one-piece swimsuit from PinkBlush Maternity is ultra comfy, featuring adjustable straps and made from fabric that stretches with you. The square neckline and ruched sides make it flattering too!


Best Maternity Tankinis

Motherhood Beach Bump 2 Piece Tankini

The gingham print is thee trend of 2021, so time to hop on board, mama! You’ll look amazing in this tankini set from Motherhood. It’s 50+ UPF so you don’t have to worry about sun exposure and sunburns on your tummy, and the stretchy nylon/spandex material will ensure you’re comfortable all day long. “PERFECT!” raved one reviewer. “I’m in love with this suit! It’s so cute and is extremely flattering. Covers my boobs more than any other suit I’ve had. I’m 25 weeks and definitely have room to grow. Also, it seems like it’ll transition well to postpartum. Bottoms are under the bump style. Top is adjustable straps and supportive for me! I’m currently around 210 lbs and size 46D chest and feel great in a XL.”


Seraphine Palm Print Maternity Tankini

Tropical vibes AND a flattering fit? Yes, please. This summer pregnancy must-have is designed to hug in all the right places, with ruched sides and a supportive band under the bust. Optional padding in the cups is a nice feature. And the twist front detailing and crisscross straps add that stylish element you usually miss out on when rocking a maternity tankini suit. The bottoms fit under your bump and will be comfortable and flattering during pregnancy and beyond. One happy mama said: “The material was good and didn’t feel cheap and flimsy. The print was just awesome and befitting of a beach getaway. This is why I am a very happy repeat customer for both my pregnancies.”


Women's Maternity Wrap Front Tankini Swimsuit

If you’re looking for a solid colored tankini, this set is a top seller on Amazon. This two piece suit almost looks like one, but makes for a much easier trip to the bathroom. The design has plenty of flattering ruche detail, adjustable straps, and removable cups for custom comfort.

Best Maternity Swim Dresses

Tempotrek Maternity Swim Dress

This vintage sailor style swim dress is pretty freakin’ cute, but that push up plunge neck makes it sexy too! “Very flattering swimsuit,” said one Amazon reviewer. “I’m really glad I bought this. It looks very nice on me. I wore it when I was 4 months pregnant and now that its summer I be wearing it 7-9 months and it should still be comfortable and look great.”

Nautical Maternity Swimsuit with Skirt

This one-piece swim has three different ways to wear it. The integrated skirt is one way (great for when you’re walking to the pool), tie it around your bump for a ruche effect, or tie it above your bump to show it off a little! The quick dry fabric is just a bonus for this beauty.
