BRIGHT AND EARLY: Ralph Lauren had a trio of socials in Lauren Remington Platt, Lily Kwong and Elettra Wiedemann to brighten up the already meticulously lit front row at his Thursday morning show at St. John’s Center Studios. None looked worse the wear from navigating the snarl of street-style shooters at the door, which had rendered Washington Street a traffic cop’s worst nightmare. Farther down the row, past the Family Lauren seats, was Jessica Alba, looking Holly Golightly in a pink tulle skirt, black knit sweater and updo. The actress has become something of a regular at the designer’s shows lately. “I just think we go well together,” she explained. “I love the family. They’re so sweet. I really respect what he’s built, where he’s come from and he’s really tight with his family. His kids are amazing; I’m a fan of Dylan’s Candy Bar.” Jelena Ristic, girlfriend of U.S. Open runner-up Novak Djokovic, rounded out the front-row notables.
