The 22-year-old model and Paper Towns actress made the event a family affair as her older sister Poppy Delevingne was also there!
This is the second year in a row that Cara has worn pants to the event.
FYI: Cara is wearing a Stella McCartney outfit, sandals, and clutch. Poppy is wearing a Marchesa dress and an Edie Parker clutch.
