Coachella is underway, and the stars are slowly (but surely) flocking to the music-filled desert festival. And what better way to jump right into things than with a trifecta of stylish sightings? A floral- and lace-clad Katy Perry and Sophia Bush, who caught our eye with her gold metallic Monika Chiang oxford flats, both checked out the Harper's Bazaar pool party on Friday afternoon. Meanwhile, Whitney Port went with something a little brighter and a little more body-conscious for the Fruttare hangout. To glean some serious A-list festival style inspiration - courtesy of Coachella's fairground sightings and parties - just keep clicking.
