If people stop liking my clothes, I'll make a record.

You want to be confident when you work out because it takes a lot to make you work out. So many women really enjoy it, but it's a hard thing and you have to make yourself do it most of the time. I think you want to feel that you look good to make you want to work out a little bit more.

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.

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.

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