"At one point, according to Lagerfeld, Kahn set up a movie camera on a Paris street corner, and every day for ten years filmed people walking by. 'You see the houses, you see the cars--and there were few changes in ten years,' says Lagerfeld, who has viewed the footage. 'The cars changed not that much. The architecture changed not at all. But the attitude of the people changed much more, in the way they walked, in the way they dressed. So don't tell me fashion is not important."
