We love this leo!! We do think, if you have a longer torso, it may be a bit on the short, but its managable, just pulls a bit on the shoulders. We don't think we can go up in size b/c the bust area would probably be too large (it's already starting to gap around the arm hole) and we think the bottom would be a little saggy. We haven't tried it, but that's what we would expect from the next size up. My daughter is a tall and skinny 11 year old that bought the Adult size XS. This is what she wears comfortably in the shorts at TF.
