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 think deep down I'm spiritual, but there's nothing I practice.

I love that you can have the language between the two worlds of technology and fashion, because I don't think that many designers get to do that.

For me, women's ski wear has always been black and, again, not as feminine or sexy as I think it could look while still having the technology there.

Running is a huge category for us. To be able to run to work and have lightweight, breathable, windproof materials you can chuck in your bag that work on technical level but also on a lifestyle level are really important to me. I work out - and I think most people do - and I want to encourage women and inspire them in a way that fits in with their lifestyle.

I run a lot. If I don't have time to go to the gym or don't have time to work out properly, I will go for a quick run. I think running is a great way to stay fit, and I really concentrate on fitting into a realistic urban lifestyle.

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 think it's very wrong to have the mass murder, every single day, of millions of animals.

You want to be confident when you work out because it takes a lot to make you work out. So many women really enjoy it, but it's a hard thing and you have to make yourself do it most of the time. I think you want to feel that you look good to make you want to work out a little bit more.
