I love this. Will be prefect for a Tigger costume. I am 5'7", 110#, usually wear size 4-6 clothes. Went for the M, and it fits well. Because of the stretch factor, S would probably have fit well too, but I wanted to be sure it is long enough. It is! A little low cut but not too bad. The stripes are not centered going up the front, which I would have preferred, but that's not a deal breaker.
