It's very difficult to do street casting with girls, because a beautiful girl in real life won't necessarily have the silhouette or the presence needed for a show.

It's a completely independent atelier and company. We develop the prototypes here. There's a pattern maker, a sample maker, a commercial team, a head of sales, an in-house production team. That's the price of independence. And in the studio I work closely with Sarah-Linh on the collection, and Nao takes care of development.

What's important for me is to find the right kind of girls who express a vision of a woman. We like girls who look smart and intelligent with natural beauty - a certain quality of skin and hair. And she doesn't look exactly like a model.

What I like to do is take something from a man's wardrobe and re-proportion it slightly. We've got another jacket in this collection with a smaller shoulder. It's the idea of subtle feminization, to make the clothes more delicate.

I don't like clothes that constrict. The idea is that they should accompany and help you. There's nothing superficial about getting dressed. Clothes can give you self-confidence and help you be yourself.

Clothes should be practical. I like the concept of easy wear. I think [86-year-old] actress Emmanuelle Riva was extremely chic. She's super stylish. At the Cesars, she was wearing this beautiful red silk dress. I don't know whose it was.

Hermès and my own brand share the same philosophy, the same vision of women, but the two aren't identical.
