I can honestly say this industry hasn't made me neurotic about my looks, except maybe my weight. I hope my clothes kind of reflect that. They're meant to make you feel good.

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.

For me, singing is the most natural thing in the world. I've grown up with it and I know I've got that gift.

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.

My mum taught me to have a soul.

It's immoral that people make money out of writing crap, but I try not to obsess about it. I don't want to spend my life being angry.

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.
