This costume is nearly perfect - it is very cute, the design makes the "mane" stay in place but out of your kid's face. The tail is removable, which is nice. The outfit breathes so your kid will not overheat. It is sized small.
My only gripe with it is that it does not have a bottom opening for diaper changes. (Also, though I loved it, I had to send mine back as it was obviously someone's return - but if I had had time to wait for an exchange, I would definitely have gotten another!)
