Music festival season officially kicked off over the weekend with the Indio, California-based jam fest known as Coachella. Over 100 performers -- ranging from M.I.A. to Morrissey, Public Enemy to Paul McCartney -- played for the hipster masses in the desert sun. Sprinkled among the fray were celebs going for concert casual attire (read: even Dita Von Teese was sporting Keds). Scope their steal-worthy style before you head off to Bonnaroo.
