Stella Mccartney faces a "million challenges" when designing the Adidas competition wear for the 2012 Olympic Games.

The fashion designer - who was announced yesterday (14.07.10) as the creator of the sportswear firm's kit for both the British Olympic and Paralympic teams to wear at the London event - admits she is already feeling the pressure of being able to create garments that suit the needs of the athletes, as well as being aesthetically pleasing.

She said: "I mean you're working with athletes. The main thing I want do is not in any way get involved with making their performance not its best. So for me I want to make them the best they can be.

"I'm obviously working with incredibly technical fabrics and dealing with silhouettes that I wouldn't normally perhaps work with.

"So there are challenges - I have a million challenges. I have to make it look good on TV, I have to make it feel good for the athletes, I have to make it work - technically it has to do its job. But I think they're all good challenges - I like a challenge."

Despite her concerns, Stella is delighted to have been given the "once-in-a-lifetime" opportunity.

She added to vogue.com: "It's incredible, beyond anything I could have ever dreamt of.

"To work on the competition wear for the Olympics, is kind of insane. As a fashion designer you don't think to yourself 'I'm going to get the opportunity to work with athletes at that level at the Olympic Games'. It really is such an incredible thing to have any kind of contact with as a designer."
