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.

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

I was first drawn to active wear because I enjoy working out, and it's very important in this day in age. I really felt women were getting the tail end of the design in active wear; not getting the technology or design we deserved. It was reserved for men. We were getting the leftover work from the sports design houses.

You feel like everyone hates you if you've got a good life, now I feel maybe it's allowed because I've had my share of sadness.

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.

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´m a real believer that just doing a little something is a lot better than doing a lot of nothing.
