Rare vintage 50s party dress

The most beautiful iridescent teal party dress you’ll ever see! Bought originally in New Orleans at Trashy Diva’s vintage shop for $500. Excellent vintage condition and was only worn once by me. Size marked is a 10, but please note this is NOT a modern 10 - fits more like a 2 or 4 at most in the waist. See flat measurements in pictures. Tulle sewn in underneath the full skirt and a full zip back. Small defect at the waist and another small mark towards skirt bottom (see pics).
