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. Crafted from pre-crinkled, gauzy cotton, this relaxed maxi dress has a free-flowing silhouette, lined for opacity, with a stretch neckline framed by adjustable spaghetti straps.
