You will definitely look like Cindy Brady or an overgrown doll with this dress on. It says, one size fits Most Adults, and I found it a little snug around the shoulder area (I wear a size 6). I would suggest if you are a size 8 or above you probably should think about a different costume. The dress also isn't as short as it appears in the picture, it comes just above my knees, which is fine.
Bottom Line No, I would not recommend this to a friend
