First of all, this isn't a toy, so I felt weird giving it low rating based on that b/c we loved the costume. My 3 year old could not wait to put it on and loved every minute of being in it. She was comfortable in the clothing part and it fit well. The velcro stayed closed on the back, which was nice. The hat tended to slip down her forehead b/c it has elastic around the bottom rim, so that was a little bothersome, but nothing that kept her down. She was recognized by some other children while trick or treating, which she loved. Some people not familiar with the show thought she was "Patrick" from Sponge Bob. She didn't like that.

As for the material...another review had said it was "great fleece" so I expected it to like a fleecy jacket...no. It was the same foamy type of polyester from which all children's costumes are made. The sleeves and pants are a thin poly, kind of like a slip. We wore a long-sleeved shirt and leggings under it while out Halloween night and she was good on warmth.
