CHEEKY CUT / FULL COVERAGE

Our Cheeky/Full-coverage swim bottoms prioritize comfort and modesty, offering the most fabric across the back and often sitting lower on the hips or at the natural waist. They provide a secure, stay-in-place fit that’s great for active beach days or simply feeling more covered. The shape smooths and supports the hips and rear while still giving a flattering, body-conscious silhouette. This classic cut is a timeless choice for those who want confident coverage without sacrificing style.

SEMI CHEEKY / MODERATE COVERAGE

Our Semi-Cheeky swim bottom strikes a balance between modest and daring, offering moderate back coverage that reveals just enough.

SEMI BRAZILIAN

Our Semi-Brazilian swim bottom offers a happy medium between Brazilian and Semi-Cheeky.

BRAZILIAN BOTTOM / MINIMAL

Our Brazilian swim bottom is known for its minimal rear coverage.

    These bottoms fit like they were custom made. I wore them for a full sailing day in the Bahamas and they stayed perfectly in place while still feeling soft and effortless.
