The consumption of animals - whether you're wearing them or eating them - is extraordinarily damaging to the planet. There are over a billion animals killed a year for food, half of which don't even get eaten. And there's over 50 million animals killed just for fashion.

The main thing I need to do is create, hopefully, exquisitely beautiful, desirable objects for my customer.

I don't use specific brands really. It's just that for my skin, I need as high an SPF factor as I can get my hands on. That's the only rule.

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.

I literally have meetings at eight o'clock in the morning, and I finish at nine o'clock at night. It sounds pathetic, but I don't even have time to go shopping.

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.

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.
