Super cute retro-looking romper!

Super cute retro-looking romper! Never worn, in like-new condition! From Forever 21. It never fit me well, but I held onto it for way too long and now want to sell it to someone who actually may use it and love it. It says it's a size large but I believe it runs very small. This would probably fit a medium or even a small better than a large, so I'm just gonna list it as a medium. Let me know if you have any other questions :)
