In the world of male modeling, there’s Calvin Klein and then there’s everybody else. It’s the exclusive that can instantly make a career. From the days when Klein himself was designing the label and tapping the likes of Tom Hintnaus to star in his Bruce Weber-lensed campaigns, Calvin Klein has set the standard for the industry. “Calvin is the job everyone wants,” Ivan Bart, the head of IMG Models, once told the New York Times. For the last 12 years, the stewardship of that legacy has been in the hands of Italo Zucchelli,who was let go by the company in a surprising announcement on Tuesday. Zucchelli had a very clear idea of who the Calvin man was: All-American, wholesome, athletic, clean-cut. Or, as he once told M magazine, “When I see them walk, they need to be – boom! – confident.” The designer was responsible for casting a murderer’s row of some of the top names in male modeling today, including but not limited to: Clark Bockelman, River Viiperi, David Agbodji, the Stenmark brothers and, most recently, Mitchell Slaggert. Here, a look back at all the male models who got their start on the Calvin Klein runway thanks to Zucchelli.
