Hair Question

Okay, I need your help on a totally superficial question. I've been growing my hair out for a while now. It's super fine, but I love the idea of long hair. I can't decide if it looks too thin and stringy though! Which do you like better?

Long? Here is it half up, half down. (Sorry for the weird self-portrait. I was sitting in traffic yesterday and bored!)

Or short? This is from a Christmas party last year.

Comment and let me know! Please and thank you. :)
