TALENT AT TRACY: Destiny’s Child member Michelle Williams glammed it up at the Tracy Reese fall collection Monday. The singer is in town to catch a few more shows, notably Tory Burch and Michael Kors. “Coming here makes me work harder because I want to be able to buy everything I see,” Williams said. Seated right next to her was Julia Stiles, fresh off of starring in David Mamet’s “Oleanna” in both New York and Los Angeles. “I’ve been reading a lot of scripts these days,” Stiles said of her next acting plan.
