How to Measure Your Hip Size

Period swimwear size chart showing how to measure chest, underbust, waist, hips, and leg opening to find the perfect WUKA fit. Get the right size first time for leakproof, comfortable, and secure menstrual swimwear.

WUKA TIP: No tape measure? 
You can measure yourself with a belt or dressing gown cord and a 30cm ruler! Tie the belt around your hips, place a piece of tape or pinch where it reaches, then lay flat and carefully use the ruler to measure the length.

Why you'll love it

WHY YOU'LL LOVE IT Everything you need for regular training in one click. The Lunafly Competition Legsuit period swimsuit with longer-leg coverage, a matching swim cap, a quick-drying microfibre towel for poolside, a wet bag for soaked kit on the way home, and a wash bag to protect the gusset in the machine. The extra leg coverage means more warmth in colder pools and less ride-up on the blocks. Sized from junior XXS to adult L. Elite Athlete Approved. 3x Olympian and 2x Commonwealth Champion, Hannah Miley MBE.

WHAT'S IN THE KIT Lunafly Competition Legsuit, Lunafly swim cap, quick-drying microfibre towel (40 x 80cm, black), wet bag, mesh wash bag.

BEST FOR Club kit starter sets, swim-camp gifting, swimmers who train in cooler or outdoor pools, or anyone who'd rather buy the kit in one go than build it across five orders.

GOOD TO KNOW Five items, one click, race-ready. Chlorine-resistant recycled nylon throughout. Two-season lifespan on the suit. The microfibre towel packs small and dries fast, ideal for poolside between sets. Machine-washable on cold delicate, no fabric softener. The wash bag goes in the machine with the suit to protect the gusset.

How it actually works underwater

Leakproof, heavy flow absorbency. No tampon.

Co-designed with an Olympian
"Too many girls quit the sport they love the year their period starts. They shouldn't have to choose."

Hannah swam for Team GB at three Olympics. She co-designed the range so it performs whether you are 11 in your first club season or swimming Masters at 32.

Elite Athlete Approved. 3x Olympian and 2x Commonwealth Champion, Hannah Miley MBE.

Reviews shown are verified customer reviews of WUKA's existing period-swimwear range, quoted as published and trimmed only for length. The Lunafly Competition range is new, its own reviews will appear here once swimmers have raced in it.

What's in the Lunafly Legsuit Kit?

Five items: the Lunafly Competition Legsuit period swimsuit with longer-leg coverage (pick your size), a Lunafly swim cap, a 40 x 80cm quick-drying microfibre towel in black, a two-pocket wet bag for soaked kit on the way home, and a mesh wash bag for the machine.

What size should I pick for the suit?

Sized junior XXS (age 9+) through to adult L. The swim cap, towel and bags are one-size. Pick the suit size at checkout, the rest come in the box.

Why choose the Legsuit Kit over the Racerback Kit?

Same five items and the same leakproof period protection, but the suit has longer legs to the knee. You get more coverage, extra warmth in cold or outdoor pools, and less ride-up on dives and turns. Choose it if you train in cooler water or just prefer more leg.

Is the suit in the kit FINA-approved for competition?

No. The Lunafly Competition Legsuit is built for club training and junior competitions, not a FINA-approved tech suit. Check your governing body's rules before senior or elite-level meets where regulated tech kit is required.

Can I wash the suit, towel and bags together?

Yes. Pop the suit in the mesh wash bag and machine wash everything cold on a gentle cycle, though hand washing the suit will preserve it longer. Air dry. No fabric softener, eco laundry detergents only.

How long does the swimsuit last?

Looked after, a Lunafly Competition Legsuit lasts roughly two seasons of regular club training, about £1 per wear over its lifespan. Hand washing or a gentle cycle in the wash bag, no softener, eco detergents and air drying will preserve the fabric. Chlorine-resistant recycled nylon, reinforced seams.

Can I wear the suit on heavy training days?

Yes, that is what it is built for. The leakproof gusset holds 20ml of heavy flow, the same as 4 tampons or 3 regular pads. Elite Athlete Approved. 3x Olympian and 2x Commonwealth Champion, Hannah Miley MBE.

Can I return part of the kit?

The kit returns as a whole. If the suit size doesn't work, contact customer support for an exchange. Unworn suits with the sanitary strip attached can be returned or exchanged within 40 days.
