Vitamin A Swimwear x Fred Segal Poppy BioRib Louise One Piece

Poppy is the collaboration's '70s red — the colorway built for a classic red-bikini moment reimagined in Vitamin A's BioRib. The Louise Bodysuit is the collection's hero silhouette: a scoop-neck, high-cut one-piece cut lean enough to read as a bodysuit under trousers or a skirt, and substantial enough to swim in without a second thought.

The Collaboration

Fred Segal x Vitamin A paired two Los Angeles institutions — Fred Segal's decades of defining West Coast style with Vitamin A's sustainable swim construction — into a 20-piece capsule across four colorways: Honeycomb, Sky Blue, Poppy, and Deep Blue.

Fit & Sizing

Runs true to size with a high-cut leg and full-seat coverage; the bodysuit silhouette sits at the natural waist with adjustable straps.

Sustainability Details

Constructed from BioRib, a first-of-its-kind swim fabric made from castor bean-derived plant material rather than virgin petroleum nylon — the production process uses meaningfully less energy and oil than conventional swim fabric, made locally in Los Angeles.

Care Instructions

Rinse in cold water after each wear, hand wash only, lay flat to dry away from direct sun.
