Calvin Klein Inc. is an American fashion brand founded by Calvin Klein in the late 1960s.

Known for its minimalism and classic style, the brand contributed to the designer jeans trend in the 1970s when Klein began adding his name to the back pocket.

Today, Calvin Klein is known worldwide for their jeans, casual collections, underwear collections and perfumes. The company's first perfume, Calvin, was launched in 1981.

Calvin Klein has since launched a range of successful perfumes that for many capture the spirit of the decades in which they were introduced, including Obsession (1985 for women, 1986 for men), cK One (one of the first unisex fragrances on the market, in 1994), and Euphoria (2005 for women, 2006 for men). Klein's perfume license now belongs to Coty.
