String Bikini Set Size Guide
📏

Measure yourself, not a garment you own. This style runs big — if you're between sizes, we recommend sizing down. The adjustable strings mean you can always fine-tune the fit.

Hips

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 it parallel to the floor.
Hips — Put the beginning of the tape measure on one hip and bring the tape across the fullest part of your hips back to where you started measuring. The strings are fully adjustable so the waistband will sit where you prefer.

Fit Tips for Diving

📏

This style runs big

The string bikini is cut generously — if you're between sizes or on the border, we recommend sizing down. The adjustable ties on both the top and the high-waisted bottom mean you can fine-tune the fit after it arrives.
🎀

Fully adjustable strings

Both the top and the high-waisted bottom feature adjustable strings, so your size doesn't need to be exact. The strings sit above the hips — measure your hips at the fullest point for the bottom size, not your waist.
📐

Top vs bottom sizing

For the string bikini top, prioritise your chest measurement. For the high-waisted bottom, prioritise your hip measurement. Since tops and bottoms are sold separately, order different sizes for each if your measurements suggest it.
🌊

After your first dive

Recycled polyester softens slightly with saltwater and wear. The adjustable ties mean you can re-tie to your preferred fit after the fabric settles in.
🔀

Mix & Match Sizes

Our string bikini tops and bottoms are sold separately so you can order different sizes for each. The high-waisted bottom sits above your hips and the strings are fully adjustable — so even if your chest and hip measurements suggest different sizes, both pieces will fit perfectly.
