Calvin Klein
　　
　　
　　why we like him?
　　
　　He is a great designer, yes, we give him that. But what really impresses us is his skill as an astute businessman and his incredible marketing skills, in making underwear ads trendy, and growing a business that seems to have limited room for diversification into a global empire.
　　
　　why is he famous?
　　
　　Calvin Klein the man, is famous, but not nearly as famous as the brand name that bears his name, and has spawned a clothing giant, with a lucrative hold of the perfume market with scents like Obsession, One and Eternity. The brand name "Calvin Klein" is one of the world's most valuable alongside Pepsi, Kodak, IBM, and Nike.
