I think the moment that I'm very proud of is building a business without using animals. And, hopefully, changing people's perception of how you can do luxury fashion.

I'm not offended or embarrassed by the fact that I design clothes for women to wear. So when I meet women who love my clothes, it's a really good, straightforward thing. It makes me feel like I'm doing my job right.

I think it took me a little while to be true to myself as a designer, and in some ways I'm still trying to do that. I have to choose things that come naturally to me. Whenever I challenge something too much or try too hard, it never quite works out.

I get a real kick out of it, seeing people wear my designs.

People work better when they are afforded to be themselves

We try to make earth-friendly decisions whenever we can, as it's part of our brand DNA.

The main challenge is technology and that's something I really push and work closely with Adidas on. They're real leaders in sports performance; always trying to push that further and further and get the best technology they can. That takes time and has rigorous testing, it's very laborious, but it's also very rewarding. You get to work with fantastic athletes, and that's a fantastic thing that has nothing to do with my day job in ready-to-wear.
