Calvin Klein is an American luxury fashion house founded in 1968. It specializes in leather, lifestyle accessories, home furnishing, perfume, jewelry, watches and ready-made garments. The company has a significant market share in retail and commercial product lines as well as in haute couture.

The company was founded by designer Calvin Klein and his childhood friend Barry K. Schwartz. The company is headquartered in midtown Manhattan, New York City.

In 1968, Calvin Klein founded a coat shop Calvin Klein limited in York Hotel with 10000 US dollars. Calvin Klein's first collection was a series of "young, low-key coats and dresses" on display at bonwit teller store in New York City.

In September 1969, Klein appeared on the cover of vogue magazine.

Calvin Klein's deal with PVH was financially backed by New York private equity firm Apax partners Inc., which is said to have made a $250 million equity investment in the convertible preferred stock of PVH, as well as a two-year $125 million secured note, all in exchange for PVH board seats.

As a result, Changjiang infrastructure has become a wholly-owned subsidiary of PVH. At first, Klein himself was one of the 15-year contracts he signed with PVH. He was still the creative director of the series, but he continued to be the consultant (consulting creative director) of the new company since 2003. Since then, the company has pulled out of more business. Barry K. Schwartz is said to be focused on chairing the New York Jockey Club. The current president and chief operating officer of PVH's CKI division is Tom Murry, who held the position before the acquisition.

After acquiring Calvin Klein, Calvin Klein announced plans to launch a new men's sportswear line to compete with the Ralph Lauren line. This line is produced by van Heusen.

Through the 2006 fall collection runway demonstration in New York City, CKI opened a 600 person showroom in an 800 square foot (800 square meter) showroom space at 205 West 39th street, South Times Square. Calvin Klein has been established since 1978.

In the 2010 report, PVH, which is responsible for the ready to wear business, estimated sales of Calvin Klein products at 4.6 billion euros.

In February 2013, pvhh acquired warnaco group, which combines Calvin Klein's formal wear, underwear, jeans and sportswear collections.

Like other fashion brands, Calvin Klein has set up the logo: "CK".

In 2004, the company purchased domain names CK.com 。 Calvin Klein is one of the few companies in the world with two letter domain names.
