Best Maternity Swimsuits of 2026

This ribbed one-piece takes the top spot because it fits the widest range of pregnant bodies without forcing a choice. The twist-front bust holds removable padding, so you set your own level of support, and a cutout at the midsection gives the belly somewhere to go. It reads as a swim dress, which flatters if you would rather not put your thighs on display.

The ruched sides are why it works across trimesters. The gathered stretch expands with your bump instead of pressing a seam into it, and the full-coverage bottom stays put when you climb out of the water.

It is a budget-friendly suit, so think of it as a one-season workhorse rather than an heirloom.

If you plan to keep wearing your suit after delivery, this one-piece is built for it. The neckline unbuttons and the cups are removable, so it doubles as a nursing-friendly suit for a poolside feed without a full change. The cross-back straps pull the load off your neck, which matters as your chest gets heavier.

Ruched sides and a full lining give you tummy control and opacity once the fabric is wet. The maker recommends sizing up for a larger bust or hips, which tracks with how snug the ribbed knit runs.

The trade-off is styling. It is a plain, solid suit, so look elsewhere if you want a print.

For the most coverage on this list, this tie-knot one-piece pairs a retro high-waist cut with knots at the front and back that cinch the chest in for security. A ribbed outer shell sits over a smooth inner lining, so it feels soft against sensitive pregnancy skin.

The adjustable ruffle straps and removable padded cups let you tune the fit as your body shifts, and the belly cutout keeps the front from riding up.

Because so much fabric is gathered, it can look bulky on a smaller frame, and the exact size range is not published, so check the chart before you commit.

This one is for the mom whose measurements are moving fast. A lace-up back plus adjustable straps means you can loosen the whole suit week by week instead of buying the next size. A twisted bra with removable padding handles support, and continuous ruffles run front and back for a softer look.

Summer Mae publishes a real size run here, from S (US 4-6) to XL (US 16), which takes some of the guesswork out. Ruched sides and a full lining keep the tummy controlled and covered.

The lace-up is a fit tool, not decoration, so expect to re-tie it after a real swim.

Sometimes you only need the bottom half, and these boy shorts solve the problem of bikini bottoms that ride up or chafe. A fold-over panel lets you wear them up over the belly for support or rolled down for airflow, and they are fully lined so nothing turns see-through when wet.

The boy-short leg keeps your backside covered while you chase a toddler around the shallow end, and you can pair them with a tankini top you already own.

As a separates piece, they only solve half the outfit, and the fit skews small, so measure before you order.

A plus-size body deserves a maternity suit drafted for it, not a straight-size cut stretched to its limit. This swim dress runs to a US 16 and is built for an A to D cup, with a nylon and spandex blend that holds its shape instead of thinning out under strain. Adjustable straps and removable padded cups let you set your own support.

The built-in swim skirt is why it lands here. A side tie knot shortens or lengthens the hem, and the ruched V-neck front skims the belly instead of clinging to it, while a crisscross back adds a little shape.

It is a solid black suit with no print option, and the built-in skirt reads more modest than sporty, so lap swimmers may want something closer to the body.

Pregnancy skin burns faster, so a suit made from UV-resistant fabric earns its spot for anyone who swims outdoors. This ribbed one-piece uses a UV-blocking material across the whole body, which covers more skin than a bikini and is one less area to keep re-coating with sunscreen.

The high-waist cut wraps and supports the abdomen, taking some load off the lower back, and the adjustable back lets you tune the fit from an early bump to a late one. The soft ribbed knit stretches with you.

The listing does not confirm a UPF number, so treat it as sun-smart coverage rather than a certified UPF 50 garment, and still use sunscreen on any exposed skin.

This is the shape-shifter of the group. A tie-knot skirt lets you wear the hem down for a swim dress or knot it up for a sleeker one-piece, so one suit covers a lounge day and a lap day. Built-in boyshorts sit underneath for secure coverage.

The detail that sets it apart is a hidden side pocket, handy for a key or lip balm on a beach walk. Double front straps add lift while the adjustable back straps grow with you, and the ribbed fabric has a subtle texture.

It comes in a limited size run and one core color, and the convertible skirt is a styling tool, so you will fuss with the knot to get the look you want.

For the most dress-like option, this Charmo swimdress hangs loose from a scallop-trimmed V-neck instead of hugging the body. The relaxed cut puts the least pressure on the bump, and a built-in full-coverage bottom with ruched sides keeps everything secure while you move.

A ribbed outer over a soft milk-silk lining feels gentle on pregnancy skin, and adjustable double straps plus a removable padded bra handle support. The scallop trim adds a touch of prettiness without a busy print.

The loose swim-dress shape is not built for lap swimming, where the extra fabric drags, and it runs in a limited size range, so check the chart.

A two-piece is the easy answer for anyone tired of peeling a wet one-piece down in a tiny stall. This set tops a shirred bandeau with ruffle straps and drops it onto a high-waist bottom that pulls up over the bump. Removable padded cups give the bandeau some structure.

The high-waist ruched bottom is the point. It supports the belly instead of cutting under it, and you can still bare a sliver of bump if you want to. The solid top and floral bottom mix keeps it from looking juvenile.

Bandeau tops offer less lift than a halter, so a very full bust may want more strap.

The flounce on this bikini top is not only decorative. It layers fabric over the bust for coverage while removable cups do the supporting underneath, a good combination if your chest has grown but you still want a two-piece. The high-waist bottom climbs over the belly for a secure hold.

It is a playful, print-forward option that photographs well, and the separate pieces let you size the top and bottom differently.

Stock on this one runs thin, so if your size shows as available, do not sit on it.

The walk from the pool to your chair is where a cover-up earns its keep. This crochet knit slips over a wet suit without a fight, adds a little polish, and comes in more than twenty colors, so it matches whatever suit you land on.

It is loose and airy, so it doubles as a light beach dress once you are out of the water.

It is a layer, not a suit, and the open crochet is sheer by design, so it covers style more than skin.

A tankini is the middle path between a one-piece and a bikini, and this one gives you the bathroom convenience of two pieces without baring the belly. The top drops into a peplum ruffle hem that floats over the bump, while the high-waist bottom pulls up for full coverage underneath.

Quick-dry stretch fabric and removable cups make it easy to wear from the first trimester through the third, and the size run spans a 34 to 43 inch bust, so it fits a range of chests.

The ruffle hem adds visual volume, so if you want a sleek line it may be more fabric than you like, and hand washing is recommended, which is a small chore.

The budget pick on this list still covers the basics a pregnant body needs. It is a two-piece, so restroom trips do not mean peeling off a wet one-piece, and the high-waist bottom gives full over-the-bump coverage. A polyamide and elastane blend keeps the stretch through every trimester.

A button-front top adds nursing access after delivery, which stretches its value past pool season, and removable padded cups with adjustable straps stop the top from slipping. Ruched sides handle tummy control.

As the low-cost option it is a plain, no-frills suit, and the button-front is a nursing convenience rather than a full drop cup, so it takes a moment to manage.

For a deeper neckline that still holds the bump, this ruffle V-neck monokini leans a little dressy. A built-in bra with push-up padding gives the chest some lift, which many moms want as their bust grows, and the ruffle detail softens the front.

The criss-cross lace-up back is a real fit tool, letting you loosen the whole suit as your ribcage and belly expand instead of sizing up. Ruched panels keep the tummy controlled and the line smooth.

The push-up styling and open V mean less coverage up top than a scoop or halter, and Summer Mae suggests sizing up if you are between sizes.

Not every mom wants fabric pulled up over the bump, and this bikini is for the ones who would rather sit the bottom below it. A low-rise scalloped bottom rests under the belly, letting the bump breathe, while a scalloped scoop-neck top keeps the look pulled together.

Adjustable straps and a back hook let you dial in the top as your chest changes, and removable pads add shape. Cupshe publishes a clear XS to XL run, so sizing is less of a guess.

An under-bump cut offers less belly support than a high-waist style, so it suits earlier trimesters or moms who simply prefer the feel, and as a two-piece the coverage is up to you.

If you want a one-piece with some detail without going full cutout, this suit puts the interest on the back. A back hook closure with a cutout gives shape from behind while the front stays covered, and a shell-stitched ruched panel adds texture over the belly.

Adjustable straps and removable soft cups keep the fit personal as you grow, and the ruched front doubles as tummy control. The XS to XL run makes sizing straightforward.

The back cutout means slightly less coverage there, and it is a solid-color suit, so it is more subtle detail than statement print.

For a mom who does not want ruffles, knots, or lace-up hardware, this pared-back one-piece keeps it simple. Spaghetti straps and a small front cutout give it a clean line, and a stretchy skin-friendly fabric moves with the bump.

Adjustable straps and removable padding cover the practical needs without extra fuss, and a higher leg cut lengthens the look. It is an easy grab-and-go suit for a quick dip.

The thin straps and light padding mean less support for a fuller bust, and the minimal cut shows more skin at the midsection than a full-coverage suit.

The front-cross drape is the signature here. Fabric crosses over the chest and gathers toward the ruched sides, which flatters a growing belly and adds a bit of adjustability where you need it. A removable padded bra handles support.

The stretchy fabric is soft against sensitive skin, and the ruched sides expand as your bump does instead of pressing in. It reads as a simple, feminine one-piece.

The care label calls for hand or dry cleaning rather than a machine wash, which is more upkeep, and it comes mainly in solid colors.

Maternity does not have to mean matronly, and this keyhole one-piece is the proof. An open back and adjustable halter give it a going-out feel while it still holds your bump in front, and the medium-cut legs keep it from looking dated.

It is machine washable, which is more than a lot of delicate maternity suits can claim, and the halter lets you dial in lift as your chest changes.

The open back means less coverage and less support than a full one-piece, and stock is scarce, so your size may be hard to find.
