Vintage ONYX Nite Iridescent Brown Halter Cocktail Dress

Vintage ONYX Nite Iridescent Brown Halter Cocktail Dress burnt orangey brown color with a large crystal broach like a embellishment on the front. size tag has been cut out but I belive it fits like a 10 ish. can provide measurements if needed. 17"-17" from armpit to armpit the material is light, flowy, has some stretch/"give" to it, and looks like "different" colors when moves. so beautiful! in EUC
