The most fascinating part is how fashion just attracts all these social rejects, if you will, from around the world, encourages individuality. They're the people who make the industry tick.

One cabbie chastened me by saying that the fashion industry was doing harm to young people, who are trying to live up to an unrealistic ideal. It prompted me to make body image and diversity key issues on 'The Business of Fashion.'

Fashion is an industry of action, not discussion.

For someone who comes from my business background, getting fashion people aligned around certain things can be a challenge. In a way, the industry is so forward-looking. And yet, sometimes people in fashion are not open to change.

I'm regularly speaking at London Business School and Harvard Business School. They're the next generation of leaders in the fashion industry.

Digital has really made the fashion industry a lot more transparent. So people can see and understand how the industry really works, and participate in an industry that was very inaccessible to people. The only thing that people used to see before was the end product. Anyone can participate in it now.
