Do you think this will be enough to keep me warm at my friend's house?

Ha ha! This is a lot of clothing. I think its too much. Don't use 5 pairs of fuzzy socks, only one pair. 1 fleece blanket, and everything else is fine. Just don't want you to get too hot in the night. Or maybe I'm wrong. Bring the extra blanket, just in case! Hope this helps, and have fun at the sleep over!:D Ciao.
