Unfortunately, I haven't dressed for Halloween in over a decade and a half, mostly because I don't have anyone in my city with which to celebrate it and because living in an apartment, I don't get any trick-or-treaters. I'd be tempted to get a costume at work but because my job is one where I services printers at the office of my clients, it would be inappropriate.
Though personally, if I had the time and a budget for a costume, I'd probably go for a generic Belmont vampire hunter with a leather whip and various other weapons and items.
