String Bikini Top 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.

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.

Fit Tips for Diving
📏
This style runs big
The string bikini top is cut generously — if you're between sizes or on the border, we recommend sizing down. The adjustable tie strings mean you can fine-tune the fit after it arrives.🎀
Fully adjustable strings
The top features adjustable tie strings at the neck and back, so your size doesn't need to be exact. Size to your chest measurement and use the ties to customise the fit and support level.📐
Size to your chest
Your chest measurement is all you need for the string bikini top. The adjustable strings handle the rest. If your chest falls exactly on a size boundary, go with that size — if you're between sizes, size down.🌊
After your first dive
Recycled polyester softens slightly with saltwater and wear. The adjustable ties mean you can re-tie to your preferred fit and support level after the fabric settles in.🔀
Mix & Match Sizes
The string bikini top and bottom are sold separately so you can order different sizes for each. If your chest puts you in a different size to your hips, order each piece in the right size for that measurement — that's exactly what we designed for.
