Purple halter High low Prom dress from deb

Getting rid of my extremely beautiful purple High low halter prom dress only minor damage which is shown in picture and very unnoticeable due to how fabric layers. I noticed the damage before I even wore to prom so I'm starting to think I bought it like that without realizing it. It's a size small and I bought it from Deb. Getting ready to move and really need the money and to get rid of stuff
