Your vulva runs on a delicate, acidic pH — and it is more easily disrupted than you've been told.
Cleveland Clinic and the National Institutes of Health have flagged a single, specific behavior pattern as a major risk factor. Here is the science — and the one number on the inside of your swimsuit that decides how often you spend the summer on antifungal cream.

Italian polyamide, 93/7 sculpting weave, Oeko-Tex® mill. Unlined and unpadded — dries in minutes.

Most swim fabric goes flat the moment it gets wet. Our Italian Carvico Crinkle holds its shape — when you sit, when you stretch, when you climb out of the pool. The texture is not decorative; it is structural memory built into the weave.
Our size guide lists the bust and cup ranges for both Flawless fit bands (XS–L and XL–3XL). Items run small — if you are between sizes, size up.
We have chosen our BetterTan Swimwear fabric for its perfect combination of softness and resiliency. To keep your BetterTan Swimwear suit in pristine condition, please follow our care instructions listed here.
