I think I'm going to find an off-white suit and be Dr. Evil this year. Or, I'll be Uncle Fester, something like that. I have a buzzcut, and on occasion I'll shave my head, so it's not hard to transition into costumes like those.
I may do something like Slenderman, or find some way to make use of my red Morphsuit, but I haven't had much time, money or energy to put into a costume. I'm a bit bummed about it, really. I realized far too late that Halloween was something I wanted to participate in. I'll probably just hand out candy, or find some way to BS a costume and see if I can get into some sort of Halloween party with a friend.
