Help with a Halloween costume?

ok so what i have done in the past if i didn't buy a costume i would just go though my clothes and find what i have. You could be a 80's rocker chick, you just need bright clothes and big hair, or gothic barbie if you have all black, or just be creative and do what Wednesday adams does, shes a phycopathic killer they look like every one else. Hope it helps :D
