NWT! Size 10 in light birch And everybody gasped. This is a puff-sleeve mini dress with a sweetheart neckline, puff sleeves, thigh slit and smocked back panel for a more versatile fit. It's cut from ReCrepe™, lightweight, drapey crepe fabric made with LENZING™ ECOVERO™ Viscose — responsibly sourced wood-based fibres produced through a process that reduces impact on forests, biodiversity and water supply.
