Black vintage knee length dress

Beautiful knee length vintage dress, structured. Low back with button detail, pockets, I believe a wool blend material? Heavy, well made but not heavyweight… such a unique dress! Perfect for wedding guest. Zipper and snaps in working order. Labeled a size 10 but waist is 12” flat so I believe fits closer to a size 0-2. No give at the waist. Model is 5’6”, wears a 2-4. Smoke free home.
