This costume fit perfectly and looked great on my 22 month old son. He is tall for his age, so it fit very well.  I love the fact that it's a pull over type costume that can be worn on top of clothing. So it's very easy to slip into and out of.  The only disappointing thing was that we found a small 1/4 hole in the armpit area of this costume. Wife sewed it up and it's good to go.  My son loves wearing this costume...it's soft to the touch.
