Silver-ish Short, Low Cut, Open Back Dress

This dress was purchased at Fashion Corner for my senior Homecoming. Has only been worn once. Claims to be size 3/4 but they didn't have my size but I loved it and I'm tiny and I still managed to fit in it. It has been hemmed a few inches to make it shorter. 97% polyester, 3% spandex, hand wash. Open to negotiate with reasonable offers. **I DO NOT SWAP SO PLEASE DON'T ASK**
