My son is on the larger side (six months old, 26.5 in, 19.5 lbs). This fits him perfectly. The ears stay put on his head thanks to the Velcro strap that secures under his chin. The material is soft and feels like it'll give a little warmth. This seems like it's pretty well-made and durable, too. This doesn't come with pants or shoes/socks, but you can easily find a pair of brown pants and socks (or shoes) to go with it. When he saw himself in a mirror, he got extremely excited. I can't wait for everyone else to see him in his costume in a couple weeks!
