Size 24 but with a corset back so it can fit down to a 18

This is a beautiful plum color dress only worn once. It’s perfect for prom, cosplaying, or for just getting fancy. It has no rips or tears, non smoking house, in perfect condition. It’s corset back can make the dress fit a wide range, I bought this dress online so even though I’m usually a size 18W to 20 I got a 24 for extra wiggle room. It fit me perfectly, but it also fit my friend whose a 24. Feel free to contact me for additional photos or info.
