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 do sport at the gym a few times a week, but I hate it. Work is my only remedy. I feel so twisted and horrible in the morning, but then I go to the office and I start feeling better. Work is my Tylenol. Extra-strength.

I was a fat child; I was asthmatic. No wonder I'm a hypochondriac.

I don't think you can be a designer if you don't care.

I think that we are in a very strange time, when everybody is thinking about what is going to happen, and everybody is kind of cleaning house a little bit. In the fashion world, we are doing something similar. We are taking the fake out and being a little bit more real and simple.

Some days I feel like a piano: kind of short, always in black & white, always expected to produce music.

I was thinking recently, If the body really is the new dress, as some are saying - with women buying boobs, butts, faces - then who needs a dressmaker? So I started designing spring like a plastic surgeon - everything stretchy and nude. But after three weeks, I was so bored with myself and the world, I began adding diamond butterflies and chiffon and colors. I realized that fashion is not about second skin. It's not the perfect white shirt or camel jacket. What women need is a dream.
