Amazon Maternity Swimsuits Under $40

Parents / Tyler Roeland

Summer is coming and if you’re looking for a maternity swimsuit to help you and your bump stay cool waterside, we’ve rounded up some swimsuit picks under $40 that will get you through pregnancy—and beyond. 

Personally, I've had three all-through-summer pregnancies and the one and only thing that got me through the seemingly endlessly hot and humid months was having access to a pool. For pregnant people, water can be a game-changer, so whether you’re packing up for a babymoon or just hitting the neighborhood pool, be sure to pick up a new suit so you can feel good while beating the heat.

Ruffled Maternity Swimsuit

Summer Mae Maternity Swimsuit


I’m not ashamed to admit that I own this suit and I’m not even pregnant. After birthing five children, I basically have a perma-bump so I can attest that this swimsuit is both comfortable and supportive in the abdominal area, with plenty of stretch to accommodate a growing bump. 

One Amazon shopper called this option the “most perfect maternity swimsuit,” adding that “the fit is amazing” and that it’s “so comfy” and “flattering.” The suit comes in 11 different colors and thanks to conveniently-ruffled shoulder straps, would also make an ideal suit to pull down for nursing or pumping. 

To buy: Summer Mae Ruffled Maternity Swimsuit starts at $36.99 (was $46.99); amazon.com 

Cutout Maternity Monokini

Summer Mae Maternity One Piece Swimsuit


If you’re feeling like flashing a little shoulder with your new pregnancy bod, this is the suit for you. It features Spandex and elastic on the sides to accommodate new growth through all your trimesters, and it’s available in sizes Small to Extra Large with various color options. 

To buy: Summer Mae Cutout Maternity Monokini starts at $32.99; amazon.com 

Halter Maternity Suit

MakeMeChic Women's Maternity One Piece Swimsuit


This maternity swimsuit is so pretty and has ample space up top for larger breasts, or just those magical pregnancy breasts that can grow in size overnight. It has a tie halter top, so you can get more of a custom fit, as well as side ruching and belly support. Some reviewers warn that the suit runs small, while others report wearing it even up to their due dates in their normal sizes. “It’s so flattering” raved one shopper who ordered at eight months pregnant. “It holds me in great and still shows off my baby bump without squeezing or pinching anywhere.”

High-Waist Bandeau Maternity Two-Piece 

Summer Mae Maternity High Waist Swimsuit Ruffle Hem Bikini


Get the best of both worlds in this ruffled bandeau option, thanks to a high-waist bottom that can hold up to your expanding midsection, and a bikini top that gives you even more room. Personally, I’ve always found bikinis easier than one-pieces during pregnancy because you never have to worry about the endless bathroom trips. This choice has a near five-star rating on Amazon and reviewers say it’s “beautiful” and “comfortable.” 

To buy: Summer Mae High-Waist Bandeau Two-Piece $38.99; amazon.com  

Ruffled Hem Floral Maternity Bikini 

Maternity High Waist Bikini Swimsuit Two Piece


In keeping with the bikini theme, this option adds some ruffling to the top and ruching to the bottom for added stretch potential. There are many different colors and patterns to choose from and the straps are removable, so if you prefer just a strapless bandeau top, you can easily go bare-shouldered on the beach.

Ruffle Top Maternity Bikini

Maacie Maternity Bikini


This pregnancy-suitable suit might be my favorite of all thanks to the additional coverage the longer ruffled arms provide. I’m self-conscious about my arms, so I appreciate any suit that can make me feel more comfortable—and the fact that this suit is so fun and colorful is a big bonus too. Choose from six different color and pattern options in sizes up to XXL.

Knot Crop Top Maternity Bikini 

Summer Mae Maternity Ribbed Two-Piece Swimsuit


How fun is this on-trend crop top bikini? I love how it mimics the look of a tied top and with detachable buttons, it can definitely double for breastfeeding or pumping, too. The bottoms are high-waisted and ribbed, with plenty of stretch to carry you to that due date finish line.

Crisscross Cutout Maternity One-Piece

Summer Mae Maternity Cutout One Piece Swimsuit Twist Front Criss-Cross Bathing Suit


The criss-cross cutout design of this swimsuit is so flattering, this would make a great suit for any expecting person. The side ruching and adjustable straps allows the suit to accommodate all three trimesters of growth. The pretty suit comes in 10 different color and print options.
