Hmm... well it depends if your hair is thin or thick, but I just did a major re-do of my hair...
It was about the length of yours, but it's very very thin and fine. I got several inches cut off, so it's bobbed about halfway between my chin and shoulders, and I curl it up on the ends to give it a little flip. It's got so much more life now... you might want to try something like that.
