Vintage 80s Plus Size Violet Drapey Aurora Borealis Brooch Tiered Cocktail Dress

Gorgeous 80s dress. Gorgeous iridescent Aurora Borealis Gem at neckline. Tag size 17/18. In good gently used vintage condition. There’s tiny little spots / marks here and there, which likely could be cleaned but I have not tried. Also the brooch is missing one stone. Not super noticable overall. See zoomed in photos. Fits like a modern day XL / XXL. Will list as both, but there’s only ONE available. See measurements below. Measurements laying flat, measuring across end to end, unstretched: Pit to pit- 23” Waist- 21.5” Hips- 23” Length- 43”
