Matching Swimwear for Couples: How to Nail the His & Hers Look This Summer

We're here to offer a third bold, retro-inspired his and hers swimwear that can't pack your suitcase without. 

We launched couples swimwear collection because, honestly, nobody else was doing it properly. Coordinated swim sets, designed so you and your partner can match your energy on your travels. Here's everything you need to know.

Why couples matching swimwear is having a moment

Matching couple outfits have gone from naff to genuinely cool, and swimwear is leading the charge. On social media, coordinated beach looks consistently outperform solo shots. On holiday, they're a conversation starter. For gifting, a his and hers swim set is one of the most thoughtful presents you can give a couple, practical, personal, and ready for adventure.

The key is finding matching swimwear that looks intentional rather than accidental. The difference is in the design, prints that work on both swim shorts and bikinis or swimsuits

OOSC his and hers swimwear: the collection

OOSC's couples swimwear range takes the same bold prints from our ski suit collection and translates them for the beach. The result? Coordinated swim sets that feel like a natural extension of the brand, not a summer side-project. Here are you MUST HAVE coordinated swim sets:

Baewatch - neon pink and built for attention

If there is one print guaranteed to turn heads at a beach club, it's the Baewatch. Neon pink, unashamedly loud, and available for both his swim shorts and her bikini or swimsuit, this is the one for couples who don't do subtle. Made from 100% recycled polyester from ocean-recovered plastic bottles. Shop Baewatch swimwear

Endless Summer - orange, purple and mint

Three colours that somehow all work together, the Endless Summer set has a distinctive retro palette that photographs beautifully. Ideal for beach holidays, yacht days, and pool parties where you want to look effortlessly coordinated. Each swim short comes with a matching shirt option for the perfect holiday look.

Poolside - aqua blue with rubber ring print

Playful, summery, and just a little bit kitsch, the Poolside print is exactly what you want floating around a hotel pool. The rubber ring motif on an aqua base works brilliantly on both shorts and bikinis. Shop Poolside swimwear

Fresh Prince - purple and aqua retro colour-blocking

If you're already in the Fresh Prince ski suit family, the swimwear brings the same energy to summer. The purple and aqua colour-blocking is bold enough to be a statement, restrained enough to wear all day. One of our most popular prints across every category. Shop Fresh Prince swimwear

Sustainable swimwear: the bit that matters

OOSC's his and hers swim sets aren't just designed well, they're made well. Men's swim shorts are crafted from 100% recycled polyester sourced from plastic bottles recovered from the ocean. Women's swimwear uses recycled polyester and Tencel where applicable. Sustainability isn't a footnote at OOSC, it's the same principle that runs through every ski suit, changing robe, and baselayer we make.

Choosing sustainable couples swimwear means you're not just looking good on holiday, you're actively contributing to a smaller environmental footprint. For a brand that started by making ski gear from recycled bottles, bringing that same ethos to the beach felt like the obvious next move.

How to style matching swimwear without looking like a theme park

The secret to great couples swimwear is coordination, not uniformity. Here's how to nail it:

•        Match the print, vary the fit - he's in swim shorts, she's in a bikini or swimsuit. Same design, different silhouettes. Intentional without being overpowering.

•        Add the matching shirt - most OOSC swim shorts come with a matching shirt option. Throw it on over your swimwear for a full holiday look from pool to bar.

•        Let one person wear the full colour, the other wear a neutral - works especially well with the Rainbow Road and Baewatch prints.

•        Don't over-match the accessories - if the swimwear is already making a statement, keep sunglasses, bags and hats simple.
