The way I see it, it's more about Tisci's favorites more than a coherent cast. Sounds logical to me - just yesterday I was watching the Fall 2009 Style review of his collection for the house in which Karen Elson talked about the diversity of the cast and how Riccardo likes to reach all different kinds of women.Weird casting at Givenchy. Android-ish Iris Strubegger & sexy Izabel, then Mariacarla plus Natasha..... and to top it all off they want Daphne G to join the company? Seems somewhat random to me.
