My daughter was 1.5 when she wore this for Halloween. She is average size (weight and height). She was the cutest thing! The outfit is quite durable! The only complaint is the tail has to be bent into shape so that it can stick up like the picture. If you live in a cold area, this is a perfect outfit. It kept her really warm! I thought a lion was more of a boy costume but with the red ribbon it made it girlie... but you can just remove/untie the ribbon for boys.
