14 best maternity swimwear styles 2025, according to mums
Admittedly, even thinking about shopping for maternity swimwear filled me with dread when I found out I was expecting my first baby. In fact, the idea of kicking back on a beach in this unfamiliar body - seemingly never-ending in it's growth - briefly put me off holidaying altogether.
Luckily, after a bit of research, I soon discovered that the best swimwear brands really do cater to every body. Including ones growing life inside.
The best maternity swimwear, at a glance:
That said, maternity swimsuits and maternity bikinis have to tick a few boxes before they can be considered worthy of a purchase, IMO. They need to flatter your ever-growing bump (obviously), support growing boobs, and ideally be made from breathable, flexible fabric.
Thankfully, maternity swimwear right now happens to be bang on-trend, too. Think: ruffle trims akin to the ones spotted on the Valentino and Saint Laurent runway, and bright, bold colourways that'll make that (very welcome!) pregnancy ‘glow’ stand out even more.
Having spoken to friends during their pregnancies over recent years, a frequent complaint was that they could only find boring, black maternity swimsuits. During my own pregnancy last year, however, I was delighted to stumble across really fun, flattering, trend-led and affordable swimwear.
If you've got the budget for a treat, splurging on a Hunza G suit or two is the ultimate pre-baby investment, as you can wear it postpartum with total ease, too – thanks to its stretchy, crinkle material. These were definitely the best things I bought while pregnant that I'm still wearing now. Also, for an added bonus if you're having a girl, they do mummy-and-me styles, too, so you can match with your little one next summer. I'm a boy mum, so until I find the perfect dinosaur-embellished one-piece our matching swimwear is on hold…

Why you can trust us
Website Director, Bianca London, Fashion Editor, Charlie Teather, and and Freelance Contributor, Rebecca Cope, have all become first or second-time mums over the last few years, and – alongside, you know, prepping for one of humankind's toughest physical feats and the subsequent life-altering reality of a tiny new human to care for 24/7 – rediscovering how to dress a body that was changing every single day posed a real challenge.
We didn't want to lose our personal style identities - which, conveniently for those of you reading this for inspo, are all very different to one another's - but we also wanted to celebrate and not just ‘disguise’ this incredible moment in our lives. And if we were finding this balance hard to strike, after working our whole adult lives in the fashion and magazine industry, we figured others must be too. So, we made it something of a personal/professional mission to compile the ultimate maternity fashion guides. If for nothing more than for us to refer back to if/when we ever do this pregnancy thing again, because (spoiler alert) baby brain is no joke, people…

- Made from: 88% Nylon, 12% Elastane.
- Sizes available: UK 6-12.
- Colours: 1.
Why we love it: You may think the frilled sleeves were this swimsuit's USP, but if you look closely you'll spot a really beautiful monochrome stitching moment spanning the neckline. A delicate but impactful design detail, it's great for anyone who might be looking to distract attention away from the bump and towards the swimsuit itself.
- Made from: 96% Nylon, 4% Elastane.
- Sizes available: One size.
- Colours: 10.
Why we love it: No one does stretch like Hunza G, and if there was ever a time to lean into it it'd surely be when your body is growing by the day. A timeless silhouette in a smorgasbord of shades, it's one of the few swimsuits that you can truly wear ‘bump and beyond’.
- Made from: 80% Polyamide, 20% Elastane.
- Sizes available: S-XL.
- Colours: 2.
Why we love it: There's something about a frilled swimsuit that is instantly appealing. The softness it creates around the shoulder and neckline is super flattering, and the side-gathers are great at accommodating a bump throughout all stages of the pregnancy.
- Made from: 85% Nylon, 15% LYCRA® XTRA LIFE™ Elastane.
- Sizes available: 6-24.
- Colours: 2.
Why we love it: Having never been one fore bikinis, I was surprised that the temptation to stray from a one-piece to the more revealing alternative came during pregnancy, no less. This high-waisted set is a great option, as not only do the pants have enough ruching and stretch to accommodate a growing bump but the bra also has great support and coverage.
- Made from: 84% Polyester, 16% Elastane.
- Sizes available: UK 6-16.
- Colours: 1.
Why we love it: It can be easy to lose your sense of style during pregnancy, so for fans of print - specifically animal print - who love to stand out it can be a particularly tricky time. Until you spot this leopard print swimsuit, that is.
- Made from: 83% Polyester, 17% Elastane.
- Sizes available: XS-XXL.
- Colours: 1.
Why we love it: Fuss-free, timeless and chic - this is actually everything I look for in a regular swimsuit, never mind one during pregnancy, so it was no wonder that this was an immediate winner. The super flattering - and slightly unexpected - square neckline sealed the deal.
- Made from: 80% Nylon, 20% Elastane.
- Sizes available: S-L.
- Colours: 1.
Why we love it: If you're feeling brave (read: determined not to have tan lines when you first meet bubs) then a strapless swimsuit is a no-brainer. Sure, the extra weight in your stomach may feel a little like it's pulling down the fabric and set to expose you at any given minute, but no one like's a strap mark - right? This timeless number does come with removable straps, though, should you need a little more reassurance while reaching over during the poolside lunch.
- Made from: 85% Polyester, 15% Elastane.
- Sizes available: UK 16-32.
- Colours: 1.
Why we love it: Halterneck styles are a particularly great option if you're feeling a little top heavy right now, as they lift and hold your chest in place and provide far less opportunity for any accidental exposing moments.
- Made from: 83% Nylon, 17% Elastane.
- Sizes available: XS-XXL.
- Colours: 2.
Why we love it: Another detachable strap, this royal blue swimsuit is enormously flattering and supportive. It's the perfect option if you're looking for something staple and timeless but want to avoid the wealth of black options out there.
- Made from: 94% Polyester, 6% Elastane.
- Sizes available: S-XL.
- Colours: 3.
Why we love it: Super soft and finely ribbed, this sky blue swimsuit is a great staple option for those of you heading abroad with a bump who want to avoid anything too fussy or frilly. The neckline's gentle v gives enough design detail to set it apart without screaming ‘look at me! I’m pregnant!' which - let's face it - isn't always the vibe when pregnancy symptoms are taking their toll.

Your maternity swimwear FAQs, answered:
What are the key features to look for in maternity swimwear?
Expandability, durability, longevity are the three key things to look for when shopping for maternity swimwear. Chelsey Oliver, Chief Creative Officer at maternity brand Seraphine, advises pregnant women to “look for super-stretchy swimwear fabrics to accommodate your growing bump” and to look out for gentle side ruching, which will give you even extra room to grow and will ensure the swimsuit doesn't constrict you.
Chelsey also says it's important to look for extra features that will give your swimsuit longevity, meaning it can be worn beyond your pregnancy journey. “If the swimsuit has easy access for breastfeeding, this will give you an extra reason to keep wearing after your baby is born!” It's also important to look for high-quality swimwear fabric that will last a long time and wash well, and straps that can be adjusted for better support.
Where to find plus-size maternity swimwear?
Generally speaking, it can be a good idea to head to the stores you usually shop from and simply size up once your bump really starts to grow, but Seraphine's brilliant maternity swimwear from Next also goes up to a 2XL, while H&M goes up to XL. Hunza G is another great, fashion-favourite option, as it is one-size and fits most body types.
