Red or Blonde? That is the question...

Oh my GOD, trying to make a hair colour decision is more painful than I thought it was going to be. So, here are the two pictures currently swaying my vote:

This is the red candidate

And this is the blonde candidate

I can't decide whether I'm more in love with Diana Vickers's colour or just the cut, the grown out fringe and soft waves are gorgeous. I'm so tempted to go for this look. But then I look back at the Karen Elson picture and remember how much I love red hair and how awesome it would look.

What do we think I should go for?
