Really adorable outfit and looked so cute on our 5 month old, but I ordered the small and it looks like it fits a 3 year old!  Manufacturer should really adjust the sizing on this or make another extra-small size.  The hat wouldn't stay on, kept falling over over his face, the booties could fit a 5 year old and the zipper is very short and doesn't really open up enough so it's hard to put on over his head.  But, it is very cute.  I guess he can be a dragon for the next 3 years or so!
