Now here is a girl who is dark colored and totally convincing as a blonde IMO.  Check out the cover of SHAPE.  It gives her a totally different look, but it looks believable ...g

I think she looks becoming as a blonde and definitely wayyyy better than most people who are not blondes by nature...But I still feel that with a complexion such as hers, she looks nicer with dark hair. I think maybe why her blonde hair matches better is she has never went BRIGHT blonde. If I am remembering correctly, she has always had honey colored blondes,rather than trying to go platinum and getting canary yellow instead. Which I imagine Lindsey Lohans hair looks like before retouching the photos!
