TAHARI’S THESPIANS: The new cast for Nora and Delia Ephron’s play, “Love, Loss and What I Wore,” includes Brooke Shields, Doris Roberts and Anna Chlumsky — an ensemble that inspired Elie Tahari to celebrate. On Thursday night, he opened the doors to his SoHo store for a party following the cast’s first outing at the Westside Theatre. “It’s a show about how real women feel about clothing and how clothing in turn makes them feel, and I’ve always thought clothing should be very important to a woman,” Tahari said. The actors were joined at the store by the Ephron sisters and Samuel L. Jackson, who snuck into the press line to snap his wife and cast member LaTanya Richardson with his iPhone. Shields was one of the last to leave, getting on the back of a motorcycle with her gold strappy Tahari sandals and a red helmet. Despite the star power at the store that night, one camera crew only had eyes for the designer. Tahari was being trailed by a “CBS News Sunday Morning” crew for an upcoming profile.
