Actress and mother of two Marcia Cross teamed up with DSW to host a back-to-school picnic for L.A. moms last Thursday to benefit OPCC, the largest provider of housing and social services on the Westside of Los Angeles County and one of Cross’ personal charities. Each attending mom walked away with a pair of white Converse sneakers to personalize for their children at the picnic’s custom graffiti station and a VIP goodie bag stuffed with cosmetics and accessories. Guests snacked on sammies, salads, petit lemon and pecan squares and chocolate chip cookies, and sipped iced tea and iced lattes.
