CK is a popular for its mad style amongst most fashion conscious guys. From sportswear, to denim and underwear, the CK brand is iconic and has made huge strides in the world of designer brands. Think of the fragrance line alone – ‘Eternity’, ‘Obsession’ and ‘CK One’ – each a stand-alone brand in itself. Calvin Klein’s underwear business, promoted in the 1990s with giant billboards showing images of pop singer “Marky Mark” – now actor Mark Warlberg – was so successful that the brand’s underpants became generally known as “Calvins” in everyday lexicon. As of 2008, Calvin Klein’s proceeds stood at $5.8 billion.
