Bringing sexy back

I need a change. My hair is so blah. It's all one length and not sexy. So I'm contemplating cutting it short. Danielle is totally against it because she is not a fan of short hair and was traumatized as a child by a bob all gone wrong, but I don't know, I think it will be kind of fun. The only thing I am concerned about is worrying if I can rock it like it supposed to. Here are some of the contenders... Which do you like best?
