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. An encased drawstring traces the edge of the Rose bikini top before meeting in the center with an adjustable bolo closure. The underwired design has ruched cups, slim shoulder straps, and metallic bead hardware engraved with the Onia logo.
