Known as the world’s finest designer underwear for men and women, Calvin Klein Underwear was formed in 1982 and would forever alter the way the world viewed—and bought—men's underwear. Once a utilitarian product, men’s underwear suddenly became an object of desire. New advertising campaigns communicated the message of the updated, sexy designer sensibility that distinguished Calvin Klein Underwear from all others. A complete women’s line followed in 1983. Each season since then, the brand has delivered a new line including basics, basics in fashion colors, as well as fashion-forward, trendy underwear to stores.
