Beer Girls Halloween Costumes

What should I be for Halloween?
I really need a Halloween costume … I want a good character in a film that perhaps I can type design myself and not some generic beer girl costumes. I was thinking in the white snow, because if I had to compare myself to a princess Disney would be it. I have dark brown short hair and blue eyes. Any good ideas? My roommates are Lara Croft and Betty Boop.
