I do not dislike Blake, but she really doesn't fit Chanel. I've read a lot of statements from Karl that he chose her because of her sunny personality and that she is radiant and healthy. May be Karl is trying to achieve a whole new vibe for Chanel with his decision to pick Blake as an ambassador. If I am not mistaken Leigh Lezark of The Misshapes is (or was) an ambassador, too, and you can see Leigh has that Chanel air all over her, as opposed to Blake.
