Someone from Manolo Blahnik went into my shop and said: 'These shoes are not vegetarian.' That's the highest compliment, because you just can't tell that they are, and they are. 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.

Running is a huge category for us. To be able to run to work and have lightweight, breathable, windproof materials you can chuck in your bag that work on technical level but also on a lifestyle level are really important to me. I work out - and I think most people do - and I want to encourage women and inspire them in a way that fits in with their lifestyle.

I think it's very wrong to have the mass murder, every single day, of millions of animals.

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.

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

Success financially is a measure of creative success, it is the same in all arts.
