As opposed to Nastya, Harleth, Ola, Maja, Devon, Katya R., Charlotte Lindvig and every other thin lipped, forgettable, bland blonde on the runway who makes Julia Nobis look exotic? Other than the fact that it added some interest to the casting this season, there are two reasons why I have no problem that Kendell and Gigi Hadid are getting cast in shows:
1. It is all about publicity. Thats the point of fashion shows anyway. People are paying attention because these girls are famous and models, for the most part, arent. Also, its good for the designers to make these rich families happy, since they are the ones who can afford the clothes.
2. Concepts of beauty, cheapness, bone structure, and being "modelesque" are social constructs that change with the whims of the industry. Kendell doesn't look like a model because she doesn't look exactly like the other girls who have been deemed good enough to model. It was deemed best to have a model look a certain way (tall, thin, certain features) because it looks best, but its all arbitrary and can change. So who is to say that Kendell isn't a model or can't be a model. If the people in charge say she is, then she is.
