xs navy blue sequined prom dress fishtail train thick material 100% polyester only worn once, no flaws zipper with clasp got from a small business in a mall- tag says “fiesta fashion” - for reference i’m 5’7, and 120. It was loose around my chest and waist. Everywhere else fit great. Definitely not an extra small, more like a small or medium.
