Early Halloween Spirit!

I know, I know, I know, Halloween is almost 2 months away, but that's why I'm thinking about it now. I have no idea what I should be this year. I plan to throw a small get-together where we will go out and trick-or-treat and then come back to my house to watch horror movies.
I also plan to invite this guy I really, really, like to this "party" of mine, so I have to have a great costume. I don't mind sexy, cute, or silly costumes, however I am picky. I want to look good, but seem scary; look cute, but see, dark.

I have already been the following:

A Witch (5th grade)
A Vampire (6th)
A Devil (7th)
A Dark Fairy (8th)
Bill Kauilitz (9th)

So my fellow Mibba people, what should I be? I have a few ideas like; Fallen Angel, Cat, Pirate's Wench, and that's it. I'm open to all ideas.

SO PLEASE GIVE ME IDEAS THOSE WHO READERS!!!
