The thing is Kendall never looks out of place on the runway. She is able to transform and wears the clothes so well... from gothic vibe to boho chic, she does well. She will never get the credit she deserves because she is a Kardashian...
Also, I would not say that she will never walk for Prada... I am sure people said that she would never walk for Dior or Miu Miu...
