I've learned that I am strong enough. When some people might have given up, I didn't. I found myself in situations where I had to make choices and I followed my instincts. You can't show people you're learning, because if you do, they will treat you like a kid. You have to grow up faster, not showing any fragility.

What is the Balmain girl? It’s a woman who knows what she wants and is going to express it

It's tricky because Instagram is not Grindr. I'm always trying to show my good side. I never complain. When I have a moment of sadness, I make sure no one ever sees. And while I'm so good at talking to friends or talking about my job, if you were to ask me to dinner - just the two of us, in a romantic way - I would be the worst. I'm so shy I would not talk.

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 wish fashion would have changed a bit more; obviously, there is change, but it's not enough - for example, I don't think there's enough diversity in fashion on the catwalk, in magazines. I really would love to push that more.

I think the only word I can use to describe what I'm doing today is feeling free. Of course, it's a business - it's about money at the end of the day, but it's about ideas as well. When you treat fashion only like a business, you're not going to go anywhere; when you push on that, we have the chance to express ourselves.

Even if I'm the youngest in the group, I'm the one taking care of everybody. I'm always in control, which means that I can see what everyone around me is doing, what they're going to do. At the end of the day, I make sure to never let go of that control.
