Oy Size charts

Are you unsure which size you should order the item in? You can find all the size charts for the brand Oy here; for men, women and kids in the standard sizes:

Swimwear - Women (Bikini Bottoms)

The styles are designed for functional use in the water and therefore have a slightly snug fit. As the material stretches when wet, a tighter fit when dry is intentional. If a less performance‑oriented fit is preferred, choosing one size up is recommended.
