She had it shorter before, and she looked cute with it, but this hairdo is just so ... I dunno, strange somehow.
If she woud have kept the colour it would have looked better I guess.
But she seems to be quite comfortable with it, so that's the most important thing.
It's not easy to have your long hair cut short and be happy with it, I tried it before and I never liked it, but Lou seems to be quite happy on the pics and I doubt one can look that balanced when you don't like your hair. (at least me and most women I know can't)
