Our swim briefs are designed for a supportive, sculpted fit with comfortable stretch. The waistband should sit securely on the hips without digging in, and the fabric should feel snug and supportive without pulling or bunching. If the brief feels overly tight or the waistband leaves deep marks, consider sizing up. If it feels loose or shifts when moving, a smaller size may provide a better fit. If you are between sizes, we recommend sizing up for a more relaxed feel. We’re also actively working on expanding our size range in the near future.
