Stella McCartney admits she is 'embarrassed' that she was 'so naïve' to use Kate Moss and Naomi Campbell in graduate fashion show

She is one of the world's most successful and well-respected fashion designers, but even Stella McCartney isn't immune to making professional mistakes.

Speaking to Kirsty Young for BBC Radio 4's Desert Island Discs, McCartney revealed her regret over enlisting supermodels Kate Moss, Naomi Campbell and Yasmin Le Bon to walk her graduate runway show during her time at Central Saint Martins.

"I look back on that moment and just feel a bit embarrassed that I was so naïve."

"They were my mates, and that’s who I was hanging out with when I was at college."

"I mean, Kate was living with me for a period of time and that’s what I was engaging in outside of my college life, so when it came to choosing the models for my degree show, I kind of thought, well, I might as well ask my friends."

"I can understand why it was obviously headline news, and why it probably p***** off my fellow students off a tad."

Revealing that she believed the models didn't just walk the show because of their relationship, McCartney said: "It was a very Brit moment."

"It was a moment where Brit was flying and these girls were travelling the world representing Great Britain. I do think had another person asked them I think they might’ve done it."

"It was a moment where they were like ‘yeah! We’ll do a degree show for Britain'."

However, when Young seemed cynical that this would be the case, the 45-year-old admitted: "I mean of course they were doing it for me because we were friends [laughs], who am I trying to kid?"

One side of her business that McCartney will seemingly never regret is her decision to steer clear from using fur, leather or feathers in her collections.

Asked by Young whether people had tried to change her mind, McCartney revealed that it has happened "a number of times" in her career.

"It’s never going to change for me, it’s in my DNA. And actually, it’s the one thing I think that makes my fashion brand modern and relevant and current, and I think it’s the one thing that makes the others not."

"I don’t use any PVC, all my viscose now is from sustainable wood, it’s such an exciting way for me to approach my business."
