Halloween costume for me?

So I asked this once on Facebook already and people told me "Bella from Twilight," which, NO, on top of which it's not even a costume, as I am already a pale brunette with a dejected air and scrubby clothes, and the only way to signal that I wasn't going as myself would be via spoilers from the latter novels, i.e. Alien-style abdominal ruptures. And please no Dorothy Gale (did that a few times already) and no Margot Tenenbaum (nobody got it last year).
