Every year at my work we all dress up for Halloween and it's a really fun atmosphere so I was hoping to get some help on coming up with an awesome and believable anime costume. Plus, I feel like if I had a decent costume for Halloween then I can wear it out that night as well.

ANY ideas would help, so thanks in advance!

And for all of you losers who spend your life perusing Yahoo! Answers just to mock people and make lame jokes: please don't think it's okay to waste my time just because you waste yours. :]
I have orange and red hair right now and I can style it pretty crazy. I'm willing and able to do so because I work in an awesome hair salon :]

BUT other than that, it doesn't have to be any ONE character, although it can be.
