In 1968, an ambitious young upstart from the Bronx named Calvin Klein got his start in the fashion world by opening a tiny clothing boutique in a New York City hotel. Within a year Klein and his understated, elegant designs were making regular appearances in the pages of Vogue and other fashion magazines, and soon Calvin Klein evolved into a multimillion-dollar company. Klein spent the 1970s through the 1990s transforming the fashion industry — kicking off the designer jeans craze and hiring celebrities like Brooke Shields and Mark Wahlberg to model his clothing and underwear collections in racy ad campaigns. Today Klein's empire includes around a dozen brands, including Calvin Klein, the Calvin Klein Collection, and ck Calvin Klein. Calvin Klein’s grey-label collection of men’s shirts offers an affordable alternative to the label’s higher-end designs, with fitted button-downs perfect for the office.
