Gingham bodycon romper

NWOT. Never worn!! Navy blue and white gingham pattern, halter style romper from forever 21. There's a zipper with a clasp at the top to insure it stays together. It's labeled a size L but I don't wear anything else in a large so I think it fits more like a medium. Maybe even a small medium. Because my butt pretty much hangs out. I adjusted it for the pic but there's no way it'd stay in place like that. I took the tags off then just let it sit in my closet. Just bought, this season!
