Rat & Boa Olympia Sequin Dress. XXS. A figure-skimming, scene-stealing maxi dress, the Olympia in ivory takes a classic, 90s-inspired slip and elevates it with cascading delicate sequins that catch the light as you move. It's hand-embellished by highly-skilled artisans, and cut to a chic column silhouette with delicate straps and a cut-away back. New without tags.
