Fiona Apple

The waiflike singer, who rose to fame in the '90s, was one of the weekend's highlights. Dressed in an appropriately grunge-glam combo of a silk slipdress and combat boots, she belted out her classic "Criminal" and new single "Every Single Night," among others. Click through to shop her look.

Sarah Barthel of Phantogram

Despite the searing heat during their early-afternoon set, Phantogram had us swaying to songs like "When I'm Small" and "As Far As I Can See." We covet lead vocalist Sarah Barthel's impeccably-cut bob. Click through to shop her look.
