If Coachella was about nailing that desert-bohemian vibe and Bonnaroo was about keeping it low-key and versatile (hey, you're camping out there for a week), then the latest fests, based in Chicago and San Francisco respectively, are all about dressing for the weather and the band lineups. We've picked out pieces that evoke that Stevie Nicks-meets-rocker chick that ensure you can dance all day long and work well for a seamless day-to-night transition.
