Maternity Swimwear

Swimwear is one of the trickiest things to buy when you are pregnant, because it has to make room for a growing bump while still supporting a changing bust. Our maternity swimwear is chosen to do both, with stretchy, bump-friendly shapes and cup-sized bikini tops and one-pieces that give real support up top. You will find tankinis, one-piece swimsuits, bikinis and swim dresses, in sizes that run well into fuller busts and larger dress sizes, so you are not squeezing into a straight-size suit. Whether you call them bathers, swimmers or a swimming costume, and whether you want your bump covered or on show, there is maternity swimwear here made to fit you comfortably through pregnancy.

What Makes Swimwear Work for Pregnancy

Good maternity swimwear solves two problems at once. It gives your belly room to grow, through features like ruched sides that stretch with your bump, blouson and multifit shapes that skim rather than cling, and swim dresses that offer extra tummy coverage. And it supports a fuller bust, which is where cup sizing matters, so your top gives genuine lift instead of a flimsy shelf.

The bonus is longevity. Because so many of these shapes are built to stretch and adapt, a lot of them keep working after your baby arrives, which makes them better value than a suit you can only wear for one trimester. Adjustable straps and forgiving cuts are what let one piece carry you across several stages.

Choosing a Style

Your best style comes down to how much coverage and support you want. A one-piece gives the most of both, and many of ours are cup-sized and underwired for a fuller bust, so browse the one-piece range if that is your priority. A tankini offers similar coverage with the convenience of two pieces, which makes bathroom trips and changing far easier late in pregnancy. A swim dress adds the most tummy coverage of all, while a bikini lets you have your bump on show if you would rather.

Sizing runs cup by cup into fuller busts and, in some styles, up to a dress size 28. If you want the widest span of larger sizes, our plus size swimwear range is worth a look alongside this one.
