Stunning alllover sequin top, probably 1980s. SIZE L, chest to 40 inches. Made of an underlayer of black open weave stretchy material covered with a layer of sequin fabric. Cool zig zag pattern between each color block of sequins. Scalloped hem trimmed with contrasting sequins, trim around ends of sleeves as well. Pulls on over head, fastens at back top with a button and loop. (I think this goes in the back, I included photos of it both ways). Fabric content tag inside.
