This costume was a really good fit.  I am a DD and it fit nicely, so wouldn't go above that unless they had a larger size.  The material was really nice and it was one of the most confortable costumes.  Got many compliments and no one had to ask what I was.  I carried the large 4' sword which made it more dynamic than just a Babe-a-lonian, but a Lonian Warrior.  One thing I would say is the arm cuffs could be a slight larger, although they never fell off and they were comfortable and secure on me they may not be on a larger wrist/forarm, so having a couple of inside hooks may help with a little adjustment.  One perk was I even washed it in a gentle cycle and it looks great.
