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.

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 confess to being a frustrated musician.

I feel like a different person since my mum passed away, like I'm driving a ship with my husband alongside me and we're leading these four children into unknown waters.

I'd rather people turn up than not. And of course I'd rather have people be enthusiastic.

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.

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.
