I had a lot of trouble finding a Mickey costume for my 2 year old and settled on this one. It is all one piece, just as a warning, child has to step in from the top. It also just fit my 2 year old and I"m pretty sure I had to buy a 3T-4T but I might be wrong. The headpiece could have fit a baby so don't expect to use that unless your child has a really small head, but the 'cap' type thing is kind of weird anyway so I just got a new pair of ears on amazon that were great for $10.  He looked cute but it is sort of a goofy costume.
