This costume is so cute & my son looked great in it! He's 4 years old & is tall for his age & the 4-6 size fit him perfectly. If my son could have worn this costume every day, he would have. I gave this costume 5 stars b/c it served its purpose for all the Halloween events my son wore it for. But he continued to wear the costume after Halloween & it's now falling apart. The mask is very flimsy & broke the 3rd time my son wore it. We hot glued it back together, but it didn't look the same. But otherwise a great looking costume.
