Masks: Instant Coolness.

I'm teaching a class at a theater right now, and we're doing all sorts of things relating to costumes and puppets and such. One thing we did was make masks. The great thing about a mask is that it instantly changes who you are, no matter what clothes you are wearing or what you look like.
In fact, the transforming power of masks kind of freaks a lot of people out. I mean, who wants to see somebody with a big ol' latex mask with the face of some politician on it? Yuck.
And, fear of clowns might also be related. People you can't recognize even though they are right in front of you. Freaky.
Anyway if you're looking for a super-quick way to be cool on Halloween, all you really need is a mask. We made these with sticks to hold them, but you could certainly also attach them to your head. I also love how you can extend the top to look like flames or a hat or hair or something.
