This costume is WARM. Very very warm. The coat is nice and fuzzy and keeps me warm. But then when I don't need to be as warm I can wear it without the coat, which is nice. This is the first costume I'm truly happy with. It was hard finding the material for the shirt, but finally Walmart of all places had it, so yay. The socks were the first time I ever dyed anything. That was an adventure all its own.
