It's amazing to see there aren't boundaries around gender. My menswear business has changed over the years as far as what men are daring to wear. And women, too. Men wanted to look tough, but now they realize you don't have to look like your granddad or dad. You can show a more feminine side.

You're taught that you need to please magazines, to please the fashion elite, and that if you do everything the right way, everyone is going to love you. But I decided not to follow some of the rules. My girls from the runway were not just models - they were soldiers. They helped me bring my ideas to life. I was talking about sexiness, about diversity, about different shapes of bodies. I was following my instincts and learning that it would not please the fashion elite. And I think this is the real luxury, to be free to express yourself. Freedom is luxury to me.

I actually am locked away. I think I have 4.6 million Instagram followers, which is obviously a great way to communicate my work and my life. But it's also a form of protection, because I don't want everybody to see my process. What I want to share in the pictures I post is something dreamier than reality. I love solitude. I love escaping into my mind and sketching. Sometimes I travel alone. I'm the first one at the office in the morning, the last one closing the door. People don't expect that, because on Instagram I have a reputation as a party boy who takes selfies all day.

I think fashion is fashion: Sometimes you dress people that you don't know, and sometimes you dress people that you actually know.

When you become controversial, when you want to promote new ideas, you need to be the face of it and not be scared.

It's really sad to me that we even have to talk about diversity in the fashion world today. That I would love to change. Diversity should be normal.

What I'm doing now is having people with and around me to build what other designers built before - like Pierre Balmain with Josephine Baker, Audrey Hepburn, Dalida, Brigitte Bardot.
