Collaborating with photographer Nick Knight, Diesel goes happy for its spring-summer 2015 advertising campaign with creative director Nicola Formichetti explaining, “There are so many crazy things happening now that you don’t see people just having fun anymore. The challenge was to work with an avant-garde photographer, Nick Knight, and get him to do something he’s rarely done – which is shoot people smiling.” The cheeky spring advertisement includes a diverse cast of models including Gryphon O’Shea, Charlotte Free, Bruce Machado, Kiko Mizuhara, Diego Barrueco, Surren Senevirate and America’s Next Top Model contestant Chantelle Brown-Young.
