I think not!

Halloween's just around the corner, and I kind of want to start thinking about this already so I won't find myself procrastinating the last minute.
My friends and I sort of go all out during Halloween. We come up with ideas, plan fun stuff to do for the night... you get the point. However, we're a group of 'DIY' people and we'd rather make our own costumes or at least, come up with ones using clothes we already have. We promised we'd never resort to buying already-made costumes from actual costume stores - except for small accessories here and there that we may need.
Two years ago, I was a flower child hippie. Last year, I was Snow White. This year, maybe a 40-50s pinup? Rosie the Riveter? Hermione??
So here I am, coming to you guys for help, yet again. I want to find out what you're going to be for Halloween, who you have been the last couple of years, and if you any other suggestions. It needs to be unique, and no slutty costumes, please!! Very important. Haha. I'd love to hear your ideas!
