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.

I think my mum was really very ahead of her time. She wore very little makeup. She really explored the way that she wore clothes in a very honest way. She wore a lot of vintage stuff and mixed it with bespoke men's tailoring and things like that. That was a huge influence on me, seeing a woman in the spotlight carry herself in that kind of way. But mostly, for me, it was just that she was an incredibly honest and sort of natural person.

The really great thing about my shoe store is that there's not one dead animal in it.

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 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.

I am a fashion designer. I'm not an environmentalist. When I get up in the morning, number one I'm a mother and a wife, and number two I design clothes. So the main thing I need to do is create, hopefully, exquisitely beautiful, desirable objects for my customer.

People think I'm strong, but actually I wanted to crawl away. I thought, I'm going to live in the country with my horse and I'll get a nine-to-five; I don't need this.
