Beyonce’s little sis, Solange Knowles, played DJ at the launch of venture capitalist Chris Burch’s 7,200-square-foot C. Wonder store in SoHo on Tuesday. Burch’s brightly colored store, similar to his ex Tory Burch’s line, offers “value luxury.” Solange went on a shopping spree, picking out belts, a heart-shaped waffle maker, a cardigan, ballet flats and an iPad docking station shaped like a pig after she’d spun tunes. She was spotted on a Delta flight to LAX the next day in coach.
