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 don't plan massively in advance.

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

A little black dress is something to rely on. To fill you with confidence and ease. To have an attitude that is pure and effortless, yet sexy and classy.

My mum taught me to have a soul.

I didn't want to be thirtysomething and not know what I was going to do. I was quite afraid of that, there were quite a lot of aimless kids around, in that 'other' side of my life, who didn't really know what to do because they always had a bank balance to fall back on and they were quite lost.

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.
