Some brands talk about they way their designs are based on a traditional style. Levi's, however, is the tradition of blue jeans. They invented blue jeans and have been the first and last name in blue jeans since 1873. There is only one way you become the leading brand that long--through consistent quality. In 1986, they did it again with their line of Dockers pants for men, who need a casual pant that fit somewhere between his 501s and his suit. Dockers has been in a league of its own ever since.
