"The fur industry gets to fashion students so young, paying them to use it," McCartney told The Telegraphin a new interview. "But even if you don't care about the millions of animals killed for fashion, it's not sustainable, and it's not modern. Every other industry tries to move forward, apart from the fashion industry."
And while McCartney has stuck to the principle of not using "leather, skins, feathers or fur" in her designs, she also said that it has had an effect on her success and that her accessories business could be 5x bigger if she used animal materials. Still, she said her brand will not compromise when it comes to ethical fashion.
"There are a lot of designers who are very fuck you when it comes to using fur,' she added. "If it's wrong to do fur, then they're going to do it…But given that there are only about three of us who don't do fur, they're not being very punk. They're just complying with every other fashion house."
