White Backless Bodycon Midi Dress

Gorgeous white backless dress for new years or clubbing! Bought this pre-pandemic and was so excited to wear it for a dance event, but never got around to it and now I'm no longer a size 4! This dress is polyester which I don't usually go for, but it has more of a milk-silk feeling, like a jersey knit but smoother. It's labeled as a medium but it is more of a 4/6. Make me an offer, I'm always willing to negotiate!
