Who's That Chick ?- Pull&Bear autumn 2011

Last month I came across some pictures from Pull&Bear's lookbook. I tried to find out who the model is but I was unsuccessful. If you know this girl please write what her name is. This is one of the campaigns when the model overshadowed the clothes.
I love her hair and I wonder if it's real, anyway, it looks gorgeous. After looking at model's hair I am ready to notice the clothes. I like some single items from the collection but I don't really think they are well-matched. The best, in my opinion, are the outfits in the first two pictures.
