Iridescent strapless party dress

Fun party dress that has a built in bra and zipper in the back. It measures about 28” from top to bottom (top of the sweetheart neckline). Great for big busted ladies out there. The dress says a 10 but it fits like a 4- I don’t know if it’s that old school sizing or a mislabel. Worn less than 5 times. No stains or blemishes.
