Fit Notes
- The triangle top is fully adjustable — ties allow you to customize the fit at the neck, back, and sides.
- If you are between sizes, we recommend sizing up for the top and sizing down for the bottoms for the most flattering fit.
- The thong bottom follows the same sizing as the regular bottom.
- Our swim fabric has a natural stretch — it will conform to your body after the first wear.
