100% Silk Description from Trashy Diva's website: This uniquely tailored dress was adapted from a vintage original. This has a longer sleeve with curved edge that can be worn cuffed or long as shown. The shoulder features a curved yoke with gathering, and the front has bias cut gathered ruffle pockets!! This dress can be worn with or without the wide matching belt. The skirt length is approx 24" on the 2, so it will fall around the knee on most. We are all crazy about this for its unexpected vintage details and the easy fit lightly bloused bodice. Fabric: Heavy Weight Silk Crepe De Chine Lining: Unlined Small seam stress under both arms.
