I kind of want to go as Severus Snape from Harry Potter, but I have no idea where to even look for the jacket. (Well, technically I know they have very similar ones on a few super-expensive goth sites, but spending $300 for Halloween would be completely stupid, so that's no help...) I haven't tried eBay yet though, so there may be hope for that idea yet.
I was also thinking of just being a random Slytherin student; I already have a white button-up shirt and I'm sure at least one of my black skirts would work. I also have a lot of snake jewelry that would go really well, so basically all I would have to do would be track down one of those HP ties that Hot Topic used to sell.
I'll probably just end up making some kind of vampire costume out of a wig from a Halloween store and a bunch of stuff from my normal wardrobe though. I'm sure I could make a pretty good outfit from a full-length black skirt and a corset with some lacy gloves and jewelry. I feel kind of pathetic, knowing I can create costumes out of my everyday wardrobe though. sweatdrop
