Vintage Tan and Beige Flowy Gown

Exceptional piece, I bought it because it was so pretty but never went anywhere to wear it. Labeled as size 12 but those are vintage sizes. Fabric is polyester , sheer cape is attached and covers the sleeveless bodice. gown measures 56” long waist laid flat is 14” and bust is 16” and fabric has some stretch and give. Butterfly sequin fastener needs a new snap sewn in.
