The Best Period Swimwear

There is a particular kind of liberation in walking towards the water without doing the mental arithmetic. No counting hours, no tucking anything away, no quiet anxiety about pale-coloured towels. Period swimwear — the genuinely good sort, with leak-proof technology woven discreetly into the gusset — has become one of the most quietly revolutionary categories in swim, and the best of it looks nothing like the clinical "solutions" of a decade ago. These are swimsuits and bikinis you would happily wear on a Riviera lounger, period or no period. Below, our edit of the labels worth knowing, from the Australian pioneers to the cult American newcomers, with notes on fit, absorbency and how to wear them without a single second thought.

Modibodi — The Original Innovators

If period swimwear has a founding house, it is Shop Modibodi. The Australian brand engineered the first leak-proof swimwear most of us ever trusted, and the technology still feels a generation ahead — a slim, chlorine-resistant lining that absorbs light flow without bulk, dries quickly and gives nothing away. The one-piece styles, in particular, are beautifully cut: high-leg, scoop-back, the sort of thing that reads as a chic black maillot first and a clever piece of engineering second. For anyone new to the category, this is where to begin.

Ruby Love — Coverage With Confidence

American label Ruby Love (formerly RubyLove) built its reputation on period-proof swimwear designed for real bodies and real days at the beach, and it remains the most reassuring name for heavier flow. Shop Ruby Love for built-in absorbent panels that hold their own through a long swim, plus a generous size range and supportive one-pieces and tankinis that feel made for actual movement — diving, splashing, chasing children — rather than posing. The aesthetic is sportier than Modibodi's, in the best way: think capable, colourful and entirely unbothered.

Saalt — Sustainable & Seamless

Saalt approaches periods with the calm, design-led sensibility of a wellness brand, and its swimwear follows suit. Shop Saalt for seamless, second-skin pieces in muted, modern shades — sage, terracotta, soft black — with a sustainability story to match (the brand is a certified B Corp). The cuts are clean and contemporary, the leak-proof lining genuinely undetectable, and the whole thing arrives with the kind of considered packaging that makes you feel looked after. A lovely choice for lighter days and for anyone who wants their swimwear to align with their values.

Speax & Knix — From Underwear Authorities

It makes sense that the brands who perfected leak-proof underwear would translate that expertise to the water. Shop Knix and its sister line Speax bring serious absorbency credentials to swim, with bikini bottoms and one-pieces that quietly hold up to two tampons' worth of protection. The fit is supportive and flattering, the styling pleasingly understated, and the bottoms can be bought separately — useful if you want to pair leak-proof briefs with a favourite top you already own. Reliable, grown-up and refreshingly low-drama.

Cheeky Wipes & Wuka — The British Names

For UK shoppers who would rather buy closer to home, two homegrown labels lead the field. Shop Wuka, the British period-pants pioneer, whose swim range carries the same trusted absorbent technology in flattering, well-priced styles. And Shop Cheeky Wipes for a similarly practical, eco-minded approach with genuinely useful leak-proof bottoms. Both ship quickly within the UK, sidestep customs entirely and tend to land at a gentler price point than their international counterparts — a sensible place to start if you are testing the category before committing.

How to Wear It: Fit, Flow & Styling

A few notes from the edit. First, fit is everything: period swimwear relies on the gusset sitting snugly against the body, so size for a close, secure fit rather than a relaxed one — a bottom that gaps will undo all that clever engineering. Match the absorbency to your flow and your plans; most leak-proof swimwear is designed for light to medium days or as reliable back-up alongside a tampon or cup on heavier ones, and there is no shame in doubling up for peace of mind. Rinse in cold water straight after swimming and air-dry away from direct heat to protect the lining's lifespan. As for styling, a sleek black leak-proof one-piece is the most versatile thing you can own — throw it under linen trousers and a straw hat and it becomes a bodysuit by lunch.

Freedom, it turns out, is the chicest thing you can pack.
