Scuba Bikini Set Size Guide
👙

Best fit for A–C cups. Built-in cups and a supportive band keep everything in place. D cups, size up for the best fit.

📏

Measure yourself, not a garment you own. Body measurements give you the most accurate fit — especially important for dive wear that needs to stay put under your BCD or wetsuit.

Tap to see how
Chest / Bust — Wrap the tape around the fullest part of your chest, keeping it parallel to the floor. Bring the tape under your armpits and across your shoulder blades. Don't pull too tight.
Waist — Find the narrowest part of your torso, usually just above your belly button. Stand naturally — don't hold your breath or pull in your stomach.
Hips — Stand with feet together. Wrap the tape around the fullest part of your hips and seat, parallel to the floor — usually about 8–9 inches below your natural waist.

Between sizes? We recommend sizing up — a slightly roomier fit is more comfortable for long dive days.

Fit Tips for Diving

🤿

Snug is correct

Our scuba bikinis are designed to fit close to the body so they stay in place under your BCD or wetsuit through multiple dives. If it feels slightly snug on land, that's right — a looser fit will shift and bunch underwater.
🩱

Layering under a wetsuit

If you plan to wear your bikini under a wetsuit, size true to your measurements rather than sizing up. A close fit is more comfortable and more effective as a base layer under neoprene.
📐

Top vs bottom sizing

For bikini tops, prioritise your chest measurement. For bikini bottoms, prioritise your hip measurement. If your measurements fall in different size brackets, order different sizes for each — they're sold separately for exactly this reason.
🌊

After your first dive

Recycled polyester softens slightly with saltwater and wear. If your bikini feels very snug at first, it will relax a little after the first few dives while maintaining its shape and support.
🔀

Mix & Match Sizes

Our bikini tops and bottoms are sold separately so you can order different sizes for each. If your chest measurement puts you in a size S top but your hip measurement puts you in a size M bottom — order both. That's what we designed it for.
