What are You Dressing Up as for Halloween?

So tonight's the night, my friends: Halloween. You've been planning for weeks or you're going to toss some half-assed costume together from stuff in the back of your closet, but either way, you're dressing up as something. What is it? And is it… sexy? Me, I'm going as Zombie Jimmy Stewart. Not gadgety, I know, but I'm hoping it'll go over well. So, what about you? Are you doing something really ambitious? Let's hear about it! Pictures and video are greatly encouraged! And if you need ideas, hit the jump for the classic web video Girl's Costume Warehouse.
