Date to movie with boyfriend? :)?

i know i know, i should be comfortable and wear what i want around him, which i do, but this is another type of date. this is a double date and i will be with him and his best friend and his girl friend. i love fashion and getting new ideas. it's quite chilly here right now, but i don't want to bundle up. if anyone has any suggestions on hair, makeup and clothing..i would really appreciate it :)
