I get a real kick out of it, seeing people wear my designs.

Depending on the season, between 20 and 30 percent of my collections contain some sort of eco or sustainable element, whether it's a beautiful organic fabric or a natural dye. And obviously I don't use animal skins or fur of any kind.

At the end of the day I separate things; my life is my life and my work is my work.

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.

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.

People work better when they are afforded to be themselves
