Black Floor Length Gown

This sparkly black floor length dress is a size Medium (8-10). Bought it from the store Tigerlily in the mall. Only wore it maybe two times (the day I bought it and the day I realized it didn't fit me anymore). Literal sparkles on the top of the dress and sleeves, not sequins. The sash is attach to the front of the dress. Zipper in the back. Built in bra. Will need to wear heels or have the bottom hemmed.
