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
Lunafly Competition Bikin top. Useful if you already have leakproof bottoms you love, or if you want the option to mix and match. Same chlorine-resistant fabric as the full set, same compression fit, same neon. Elite Athlete Approved. 3x Olympian and 2x Commonwealth Champion, Hannah Miley MBE.

HOW IT WORKS
Performance training top in chlorine-resistant recycled nylon. Cut for compression and stay-put fit so it doesn't ride up between lengths. Pair it with the Lunafly Competition Bikini bottoms for full period protection, or wear it with your own bottoms.

BEST FOR
Mix-and-match swimmers

GOOD TO KNOW
Wash before first wear. Chlorine-resistant recycled nylon with a dye-locked neon print that doesn't fade. Two seasons of regular club training. Rinse cold straight after the pool, machine wash cold on delicate, air dry. Skip the fabric softener.

Wash and Care

Rinse, Wash at 40°, air dry inside out. Tested to 54 washes.

Composition

Main Body Outer: 80% Recycled Polyamide, 20% Elastane with a durable hydrodynamic water repellent treatment.

What's the Lunafly Competition Top made of?

Chlorine-resistant recycled nylon, the same performance fabric as the Lunafly Competition Bikini bottoms. Reinforced seams, dye-locked neon print that doesn't fade.

Does the Top have period protection?

No, the Top has no leakproof gusset, the period protection lives in the Lunafly Competition Bikini bottoms. Pair the Top with the matching bottoms for full period protection, or wear it with your own leakproof bottoms.

Can I wear the Top on its own?

Yes. It works as a standalone training top with any bottoms you already own. The compression cut keeps it put through dives, turns and lengths.

Will it fit junior and adult swimmers?

Sized junior XXS (age 9+) through to adult L. Cut to the same compression standard at every size.

Is the Top chlorine-resistant?

Yes. Built for regular chlorinated-pool training. The neon colour holds because the fabric is dye-locked, not surface-printed.

How do I wash it?

Rinse cold straight after the pool. Hand washing is best and helps preserve the fabric. If you machine wash, use a laundry bag on a gentle cycle, though all machine use reduces the lifespan of a performance product. No fabric softener, eco laundry detergents only, and always air dry.

What bottoms does it match with?

The Lunafly Competition Bikini bottoms in the same Electric Neon colourway. See the matching bikini.

How long will the Top last?

About two seasons of regular club training, looked after well.
