For its 12th year, Shaky Knees Music Festival moved both its location (from Central Park to Piedmont Park) and its season (from spring to fall). But there was no shortage of talent thanks to headliners like Blink-182, Deftones, Cage the Elephant, Lenny Kravitz, My Chemical Romance, and Vampire Weekend, and certainly no shortage of creative concertgoer outfits. Here, a small sampling of some of the looks we saw while out and about at the festival.| Atlanta Magazine
