I think an art collection is a lot like a diary. Your taste evolves with time. I try to never sell anything, because its part of my journey.

I have a passion for modern and contemporary art. I spend a lot of time in museums; I particularly like the Guggenheim, MoMA in New York or LACMA and the Getty Museum in Los Angeles, for example. I cannot wait for the Louis Vuitton Foundation to open.

The worlds of art and fashion have always been very intertwined at Dior. Francois-Xavier Lalanne and his wife, Claude, for instance, did windows for Monsieur Dior. Dior himself was a gallerist before becoming the revolutionary fashion designer we all know.

It's important to feel what the customer is feeling when he enters the shop.

I firmly believe that success lies in the combination of both talent and business savvy, and that the magic comes through partnership between both.

Clients are becoming more and more savvy. They know what's happening in the brands; they know the new products that are coming out.

Im lucky that its about fashion and perfume and cosmetics. If my father had owned a tire company, I dont know what I would have done.
