The 25-year-actress chose a plunging tulle Valentino Couture gown in deep emerald for the event.
The Grecian-style dress featured a high-waisted band and knotted straps, with a criss-crossed detail on the back.
The actress finished off the look with a pair of Jimmy Choo heels and a clutch bag.
She kept her hair and makeup fresh and unfussy, wearing rosy lipstick and styling her bob in a textured wave.
