Soleil One-Piece Swimsuit

Founded in 2009 by Carl Cunow and Nathan Romano, Onia's range — from basics to beachwear — is designed for ease with clean-cut silhouettes and high-quality fabrics to create a reliable wardrobe for every day.

A tie-front keyhole cutout and contrast binding give the Soleil one-piece its distinctive look. The suit is made from stretch tricot fabric with fixed triangle cups, adjustable straps, and a high cut at the leg.
