I purchased this from a Zimmermann private sale so there are no composition tags inside, but this is 100% Zimmermann! Part of the Resort 2023 collection, the High Tide Lift Off minidress is an artful representation of Zimmermann’s whimsical vision. Made from silk linen, this flourishing style has a sheer bodice and hand-applied 3D flowers. Care instructions: dry clean Closure: invisible zipper, zipped back Made in China Material: 53% linen, 47% silk Material II: 100% polyester Material III: 100% polyester Item number: P00753384
