Vintage Little Black Disco Dress

Super cute with gold shiny highlights on top (polyester) - Has a tiny string belt that matches the top and all loops around the waist are still intact. There is one small snag on the back of the dress next to the zipper (see last pic) - the rest of the dress is in great vintage condition. The only tag I could find is in the picture - assuming this is the size tag but even so, the dress fits more like a 5-6 even with the elastic waist. Measurements laying flat: Armpit-2-Armpit= 14” / Waist= 11” (elastic stretch to 13”) / Length= 42” - Happy to answer any questions!
