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.

Fit Tips for Diving

📏

True to size — size up if between

The one-piece swimsuit runs true to size. If your measurements fall exactly on a size boundary, that's your size. If you're between sizes, we recommend sizing up — a slightly roomier fit is more comfortable for a full day in and out of the water.
📐

Size to your chest

For a one-piece, prioritise your chest measurement first. The torso length and bust fit are the hardest to adjust — getting the chest right is the most important factor. If your hips suggest a different size, go with your chest.
🤿

Stays put under your BCD

Our one-piece swimsuit is designed to stay in place through multiple dives. A one-piece is ideal for diving as there's no gap between top and bottom — no riding up, no shifting, no adjustment needed between dives.
🌊

After your first dive

Recycled polyester softens slightly with saltwater and wear. If your one-piece feels snug at first, it will relax a little after the first few dives while maintaining its shape, support, and UPF 50+ protection.
🔀

Which Measurement to Prioritise

If your chest, waist, and hip measurements suggest different sizes, prioritise your chest for a one-piece. The torso fit is set — there's no separate top and bottom to mix. When in doubt, go with the larger size for comfort and range of movement.
