I personally don't care for lengths longer than waist-length, but again that's just me. I know there are some people who have butt-length hair who have gorgeous hair, and I can't remember how long Rain's hair is, but hers is beautiful. I think most people can't carry it off though, because it just starts to drag down their whole look and starts to look 'heavy', if that makes any sense.
