When you think about Calvin Klein, initially you think of his clothing line – specifically his jeans and underwear lines (not to mention the famous ad with a young Brooke Shields). But Calvin Klein’s penchant for perfume was equally as cutting edge as his foray into fashion. Calvin Klein turned the fragrance world on its head in 1989 when he introduced Eternity. The now legendary cologne was a pioneer scent for its time, even down to the streamlined design of its bottle. Eternity remains a timeless, classic scent today.
