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

I wanted to feel good about the way I looked. I didn't understand why style had to be sacrificed for sports technology. I found when going to the gym women were wearing their own tees, without the technology. I started to think, does it make you run faster if you wear that terrible color or sweat less if you wear that horrible fabric? And I challenged it, and the answers were not there to why we were being given poor design work. It was something I wanted to bring to women's wardrobes.

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 took me a little while to be true to myself as a designer, and in some ways I'm still trying to do that. I have to choose things that come naturally to me. Whenever I challenge something too much or try too hard, it never quite works out.

People work better when they are afforded to be themselves

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 don't plan massively in advance.
