The Grand Palais was transformed as an Art Deco mirror-mosaic salon where bouquets of white arums punctuated the runway of models walking to simple, pastel, purified silhouettes, from the froufrou to the pointed metallic shoes. Discreetly placed, they were wearing only one jewel: an anklet bracelet with white pearls. Elegance, sophistication and discretion, it can only be Karl Lagerfeld.
