We love it!! My 3 year old has developed quite an interest in dinosaurs, and Triceraops is his favorite. The costume was perfect, not scary and he loves it. It fits perfectly with room for a warm outfit under it. He is 32 pounls and 37 inches tall, we ordered a small for 3-4 year olds. He can point out the dino parts from the frill to the three horns, and practice his roaring and romping. Nicely made too.
