I'm going to a hallowe'en party on the thirtieth as an angel.
Not an awful, white dress, plastic-y wings, cheap halo headband getup though. One of my friends is really into cosplay, and knows someone who makes props for more complicated ones, and she managed to get me some wings he had made that were never collected. They're really fantastic, and I have a fancy light-up halo from Charlotte too, which she used a couple of years ago and hasn't used since.
Added to a white dress, the whole outfit looks pretty damned good, though I say so myself.
