Ask the paradigm-shifting surfers of the '70s about style, and they'll talk about being the first to ride backside at Pipeline, or carving up waves that had only ever been surfed in a straight line -- to them, style was something achieved in the water, not in front of a mirror. But catch "Bustin' Down the Door," a documentary opening today about the birth of modern pro surfing on Hawaii's North Shore in 1975, and you'll get an eyeful of audacious beachfront fashion. It reeks of the Ford era, but is somehow terribly ... now. So, if you're really intent on pulling off that authentic '70s look, ditch your American Apparel and paddle out into the lineup with these style-pioneering surf gods. We just hope you're man enough to rock the shortest of boardshorts.
