1950’s style black vintage formal

I wore this on stage for big band shows. Not sure of the vintage, but looks like a 1950s 60s prom formal. Could be 1980’s….Beautifully made. The bodice can be worn with halter straps or strapless. Zipper in back. Black sequin bodice with beautiful tulle flounces. About 31 inches from the waist to the ham. Will fit up to a 28-29 inch waist. Looks a bit charcoal in the photos but it is a jet black. I’m about a 34C cup size and it fit me. Will fit smaller. Collectible Prom Wedding Onstage Evening Classic
