Hallowe'en

Hallowe'en approaches (a scarce eight days!) and I still have no idea what I want to be. I'm going to be Professor Minerva McGonagall during the day, of course. (My McGonagall hat came in the mail yesterday; it is ENORMOUS.)

But what to be at night? No idea. I need to decide pretty quickly here, as this weekend will be my prime costume making time. If it helps, I'm going to a party, so it isn't just a "handing out candy at the door" kind of deal.

All suggestions are welcome.
