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. Made of lightweight cotton yarns, this knit maxi dress has an open, airy quality, with a crisscrossing low back and a classic boatneck that leads to long, drop-shoulder sleeves.
