The best maternity swimwear to shop now, perfect for you and your bump
Bikinis, tankinis and one-pieces that will fit and flatter your changing body 🫄🏽👙
There’s no denying that one of the most frustrating parts of pregnancy is finding clothes to fit your changing body (ya know, along with morning sickness). The struggle is only more real when it’s maternity swimwear you’re shopping for. What’s already a daunting process can quickly become a full-on nightmare thanks to a rapidly growing midsection. That’s where we come in.
Shop our fave maternity swimwear picks
The best maternity swimwear has to tick *a lot* of boxes. It needs to be comfy but not frumpy and we’re not opposed to sexy silhouettes or funky patterns and colourways as long as they’re functional. No mumma-to-be wants to feel restricted or exposed, so whether it’s a bikini, tankini or one-piece, it needs to werk. In other words, micro-biknis are off the table and we’re searching for styles that support newly big boobs, a growing bump and a dwindling tolerance for uncomfortable clothing.
Affordability and cost-per-wear are super important to us, too, which is why we’ve included some gems that can be worn post-partum and sit in your capsule wardrobe for years to come. Unlike maternity jeans, maternity pyjamas and nursing bras, these versatile picks will work whether you’re eight months pregnant or two years post-partum, and have enough stretch to accommodate your changing body.
So, whether you’ve booked a babymoon in the sun or have taken up swimming as a low-impact workout, keep scrolling for our pick of the best maternity swimwear on the market RN...
