When I see Kate Moss out and about, I think she looks more beautiful than when her hairdresser and make-up artist try and make her look like something else. And I remember when Madonna first asked Versace to book me to shoot a campaign with her, she came to see me wearing hardly any make-up, and she looked incredible.

When I had photographed Prince William's mother, I brought along a CD of Dalida, a French singer, that we played on set all day to relax everyone. I decided to do the same thing for Catherine and William. The contrast of the contemporary informal music playing in the beautiful rooms with so much history caused a lot of laughter.

I don't think fashion has to change every five minutes. I'd like these to be clothes you can wear for a long time - ten, 20 years; pass on to your daughter. Why buy vintage when you can open your own closet!

What I look for when I see a piece of art for the first time is some kind of emotional, intellectual experience, that's a combination of both of those things and is informed by my knowledge and something new that I see the artist doing.
