Scuba Bikini Top Size Guide
📏
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 — Put one end of the tape measure on the fullest part of your chest and bring the tape around the back (under the armpits, over the shoulder blades) to where you started. Keep the tape parallel to the floor.
Underbust — Put the tape measure around your body right under your breasts, where the bra band sits. Keep the tape parallel to the floor and snug but not tight.

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 bikini tops 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 lose support underwater.🩱
Layering under a wetsuit
If you plan to wear your bikini top under a wetsuit, size true to your measurements rather than sizing up. A close fit provides better support and stays put under neoprene through long dive days.📐
Size to your chest
For bikini tops, always prioritise your chest measurement. Your underbust measurement helps confirm your size — if they suggest different sizes, go with your chest measurement for the best coverage and fit.🌊
After your first dive
Recycled polyester softens slightly with saltwater and wear. If your bikini top 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 puts you in a size M top but your hips put you in a size L bottom — order both. That's exactly what we designed it for.
