Absolutely adorable, the material is furry but not too thick. My girl was comfortable trick-or-treating in a temperature of about 68 degrees. Any hotter than that and I wouldn't use it, they would sweat too much. She adored the rattle. One thing though, the costume fits a little small, my daughter is 7 months, 20 pounds and about 27" and it didn't close all the way. We had to cover the wholes hehe but it still looked very nice.
