The couture line for Viktor & Rolf turned 25 this year, so the designers took 25 looks from past seasons, scrambled the chronology and stripped them of color, and sent them down the runway in what they called the Immaculate Collection. Vogue has a typically erudite take on it, including the wry note that the Atelier staff was not thrilled when it found out it had to remake the gown I call Swiss Cheese Skirt.
