Oisri Swim

Oisri Swim is the swimwear expression of Oisrí, a New York City label founded by sisters Carleigh and Rachel Gewirtz. Drawing on their New Jersey upbringing, summers at the Jersey Shore, Irish American heritage, and lives in New York, the brand pairs bikinis and one-pieces with lingerie, clothing, and attachable body jewelry. Its collections emphasize fine details, playful nostalgia, and recurring pearl-and-oyster motifs. Oisrí returned to Miami Swim Week’s official 2026 runway calendar after appearing in 2025.
