Renvy mesh party dress

I bought this dress and I couldn't return it I'm a size 12 I bought it because it said large but I can't even get into it hence why I have it as a size 6 because I had my friend who wears a size 6 put it on. as you can see it's an extremely sexy dress and I'm really bummed that I can't wear it. there is a picture to show details and measurements. obviously it's never been worn LOL
