How does Kendall Jenner wear her Calvins? Calvin Klein doesn't really care. 

The designer had nothing to do with casting the celebriteen in his namesake brand's ad campaign, and isn't really psyched with the choice.

Fashionistareports that Klein discussed Jenner and her squad of Instagram models during an interview with Fern Mallis, executive director of the Council of Fashion Designers of America, at the Savannah College of Art and Design. 

He's not into the idea of booking models based on their social media following. Klein is, however, a Belieber.

"You know, I'm really not that familiar with it. I'm honestly not," he answered when asked directly about Kendall Jenner's ads. "I'm sure she's a lovely young woman. It's not the kind of thing I would have done, even today. Justin Bieber, yes."

Klein sold the label in the pre-social media era back in 2002. His hands-on involvement with the label he started in the '60s is limited, but the designer still has strong opinions about the company and how the industry is changing. 

"Now, models are paid for how many followers they have. They're booked not because they represent the essence of the designer, which is what I tried to do — they're booked because of how many followers they have online," he explained.

For Klein, it's not a numbers game, but how the whole thing comes together.

"However, if you take really exquisite photographs of the right people in the right clothes in the right location, and you put it online, that's fine," he said. "Just putting any old clothes on Kim Kardashian, long-term, isn't going to do a thing."

The Kardashian/Jenners will persevere after this rejection, though. They still have Balmain.
