Iris Plunged 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.

The 'Iris' one-piece is made from nylon tricot stretch fabric, featuring a plunging V-neck and an open back tempered by a wide, banded waist. It offers moderate back coverage and a flattering cut at the leg.
