9In Vogue on Calvin Klein fashion journalist Natasha Fraser-Cavassoni explores Calvin Klein's creation of one of the greatest fashion brands of today. With his easy and timeless, classic yet sensual designs, Calvin Klein created a fashion brand that made understated, all-American glamour his own - at the same time as building a vast billion-dollar empire that includes everything from underwear to perfume and pillows. His style was so influential that Vogue announced: 'if you were around a hundred years from now and wanted a definite picture of the American look, you'd study Calvin Klein.' His stylish and provocative campaigns, and use of celebrities has changed the face of American advertising.
