Kate Middleton and Prince William stopped by the Investec Derby at Epsom Downs racecourse this weekend, where Middleton continued her bridal style in all white! The Duchess of Cambridge topped off her floaty chiffon Reiss "Peacock" dress ($375, not online) with a structured Joseph jacket and a sparkly clutch and nude patent pumps, both by LK Bennett. Though Middleton stuck to her go-to brands for the outing, she mixed things up a bit by styling her signature long strands into a chignon updo, topping it off with a beige fascinator. This marks one of the only times she went out with the hair up and it looked fabulous! Click "See the Photos" for shots of Kate's Derby look, plus other royal moments of the weekend!
