Most of the major fall campaigns have debuted by now. What you may or may not have noticed is the lack of color in them. Seven major fashion houses opted for the B&W look, including Valentino, Prada Men, Yves Saint Laurent, Calvin Klein, Versace, and Bottega Veneta. This is after an especially colorful spring campaign season. For a fashion house like Versace, it’s strange to see the brand mute out its high-contrast minis and sexy to-the-floor gowns. And Valentino, who had such a lush, romantic spring campaign with Dree Hemingway, hired David Sims’s clean, stark minimalist style for its fall prints. Is this just a coincidence? Or could this be a throwback to classic fifties imagery? Click ahead to see all the colorless campaigns in our slideshow.
