Camping advice for a self-proclaimed girly-girl?

I don't know how I got suckered into it but I'm going camping for the first time with a group of my friends for 2 days next weekend. I was wondering what necessities I should bring, what not to bring, and generally any other advice you'd be willing to offer. I'm generally NOT and outdoorsy type of girl, so to be frank, I have no idea what I'm getting into.
