Stella McCartney admits designing the kit for Team GB's Olympians is out of her comfort zone.
Stella has been tasked with creating the Adidas sportswear for the British team for the London 2012 Olympics but says it has been tough logistically because she has to create thousands of products for 900 athletes.
She told Grazia: ''No designer has worked with the entire team before. Between the Olympic and the Paralympic teams, that's 900 athletes, which is thousands upon thousands of products. The magnitude of that is way out of my comfort zone. What's most mind-blowing about it is I'm serving the nation a bit, serving the team, trying to bring them together.
''All of them have very special needs. They're all trying to win gold medals.''
Stella - whose father is Sir Paul McCartney - famously asked a host of famous friends including Naomi Campbell, Yasmin Le Bon and Kate Moss to walk the runway for her graduate collection from Central Saint Martins College of Art and Design and says despite criticism, she doesn't regret it.
She said: ''My first show, I used famous models, and my thinking about that was other people in my situation would probably use those models if they knew them, so why would I go out of my way to not use them? Because I did think maybe I should not do that. But in the end I decided that's a bit strange - I'm not doing something I would naturally do because I'm worried that some people are going to make a negative judgment about me.''
