Chelsea Metallic 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 fresh take on a classic balconette suit, the Chelsea One Piece has a corset-like design with vertical seaming and lightly padded, molded cups structured with discreet underwires. It has a fuller cut in the back for more coverage and slim straps that adjust to sit comfortably on the shoulders. Inflected with lurex threads for a light-catching effect, the shimmering swim fabric has been specially sourced for its durability, resistance to pilling over time and colorfastness against UV sunrays as well as chlorinated and salt waters.
