H&M approached us to collaborate, and see if we could translate the dream we created at Lanvin to a wider audience, not just a dress for less. I have said in the past that I would never do a mass-market collection, but what intrigued me was the idea of H&M going luxury rather than Lanvin going public. This has been an exceptional exercise, where two companies at opposite poles can work together because we share the same philosophy of bringing joy and beauty to men and women around the world.

I always think, if I were an editor, and I was invited to a show, and I would have to wait for 45 minutes in the dark or in the cold or in the heat, maybe I would like to have a fresh drink or a piece of chocolate.

In fashion, we have a reputation for being such a façade, fake people, but none of the fashion people who I know are fake.

If I wasn't a designer I would love to be a doctor. That is my fantasy, my dream. A doctor will give you a tablet if you have a headache and I will give you a dress and we both make you feel good.

I think 'modesty' is a beautiful word today - and a beautiful attitude.

I work on fittings, mostly. You know, I sketch less and less in my work. I sketch for the show sometimes, but then it becomes more conceptual. But when I don't sketch, it becomes more pragmatic.

I don't think that you can write music if you don't know how to play an instrument. You have to know the basics, then you can go forward.
