I actually would think that Natasha would have it harder than Kasia and Constance because even if Kasia and Constance walked one of Karl's shows and did DG, Natasha IS Dolce & Gabbana's runway star. Since Karl was furious about girls walking Dolce&Gabbana instead of Fendi, it would be Natasha in my opinion would be hit hardest since she is Dolce & Gabbana. Which I actually don't mind since I think Natasha is MUCH more of a D&G and Gucci girl than any of Karl's aesthetics. However, I think if she's going to be at the peak of the modeling industry, I feel she may need to conquer one of Karl's brands.
But who knows, she may be the first model to not need Chanel, Fendi, or KL. Look how far she's gotten without a VI cover. But I think at some point it may become a neccesity since model superstardom has followed the typical trend of nailing Chanel or Fendi.
But then again, Natasha has not been the typical top model with her not needing a VI cover and not needing a photographer (coughMeiselcough) to grab 5 campaigns simultaneously.
I don't know what I'm trying to prove here. Except that Natasha is pretty amazing.
