1. Mick Jagger
As quite possibly the greatest frontman of all time for quite possibly the greatest rock 'n roll band of all time, it is no surprise that Mick Jagger was a huge style icon. Even though his career has spanned more than 50 years, it is the 1970s in which Jagger set a very high bar in style that very few others could achieve. Even today, there are very few frontmen who can claim their moves and style don't invoke Jagger.
Set in contrast to the relatively tame Beatles, the Rolling Stones entered the '70s as dirty androgynous weirdos who were led by Mick and despised by anyone who believed in sex-less decency. But as they dominated the sounds of rock infused by the genres of blues, disco, and glam, Mick also developed a sense of style that touched on all these subcultures to create the archetype of rockstar. Essentially, Mick invented the notion of swagger.
