What are some good Halloween costume ideas?

Lol a hobo would be fun to dress up for school. Baggy sweats, messy hair and you dont have to shower

I am going as a Fire Spirit. It's quite simple. I'll dress in all white and spray my hair red to look like flames.

It depends on what you like, mostly. Do you have a favorite book/movie/TV character? I'm being Gandalf the Grey for Halloween (even though I'm a girl). Have you ever been told you look like a famous person or celebrity? Dress up as them. Be something random; previous costumes of mine have been a toothbrush (box + pipe cleaner bristles), toothpaste (when my brother was a toothbrush), a refrigerator (box + creativity), a magician with my (real!) rabbit in a top hat, a Lego, etc. You could go as a statue or painting (http://www.therpf.com/f24/doctor-who-bli%E2%80%A6 http://www.blameitonthevoices.com/2011/1%E2%80%A6 greyscale (http://boingboing.net/2010/10/31/diy-hal%E2%80%A6 or other awesome thing.

OH! Do what I'm doing! I'm gonna cosplay as my favorite manga (comic book) character. I'm gonna be Ciel Phantomhive from Black Butler. Whoever gave me thumbs-down. Don't knock it till you try it.
