Kate Middleton looked stunning in a ladylike skirt, blazer, and fascinator alongside her top-hat-wearing husband, Prince William, at the Epsom Derby in Epsom, England, today. The Duke and Duchess of Cambridge were joined by much of his family, including brother Prince Harry, the Queen, and cousins Princess Beatrice and Princess Eugenie. Kate's parents James and Carole Middleton also joined in the festivities. Prince William and Kate Middleton grace the June VF cover and recently revealed the plans for their upcoming North America trip. Kate will reportedly bring a number of outfit changes for every day, which she will select herself. Her gorgeous hair was pinned back for this afternoon's outing, and the family cheered on the Queen's horse, Carlton House, who came in third. Earlier this week, it was Prince William himself atop a horse for a polo match in Chester.
