"My son is almost 3 and wears a standard 3t that are still plenty big and a little to long. This costume is sized very small. It is to short in the stride and the feet are about 2 inches above his ankle. His heart is set on being a lion for Halloween and it is very disappointing to him that it doesn't fit properly. The mane is also no where near as fluffy as it appears in the picture. The elastic on one of the feet was broken already. But my son couldn't wear the elastic anyway."
