I wasn’t sure what to put because the romper I got fits perfectly! The only reason I did put small is because I ordered a size up. The large fits me perfect but I feel I’m normally a medium in most other brands. I’m also a tall girl at 6ft. Because I ordered a size up it fits me well, a little hard to get my shoulders in but again I’m tall, and once it’s on the fit feels great and I love the material! I’ve gotten so many compliments on it!
