Halloween costume help!!!?

Aight guys I have a halloween party to go to tonite and i need a costume to wear. I'd like to keep it cheap and simple since it's a dance party. I have a neon yellow jumpsuit i would prefer to use but i also have aviators, a brown leather jacket, a cape, a grim reaper hood and some other basic stuff. Any good ideas of what I could do with just stuff at my house and minimal spending?
