I Need New Hair

My hair is probably at its longest ever. I do love the convenience of just being able to throw it up in a bun, but it just kind of hangs. I *think* I look best with medium-length hair, but if I chop it off will it just seem like I got the inevitable MOM haircut?

Current inspiration:

Brooklyn Decker's bob.

My fave Nicole Richie look.

Jen Aniston's bob (my hair is NEVER that smooth!).

Or go dark and add more fringe?
