Kate Middleton arrived at a “secret” engagement in London last night in a show-stopping cream dress. The Duchess of Cambridge looked absolutely gorgeous in the demure high neckline dress, believed to be a design by Roland Mouret, she teamed it with crystal-studded Jimmy Choo Vamp sandals that revealed crimson-painted toenails. She carried a diamante clutch bag that matched her shoes and sported a pair of chandelier-style diamond earrings. Kate was accompanying her husband, Prince William, to one of the most elite dining clubs in the country.
