Kate Middleton's Regal Style Shines at Coronation Concert.

Princess Kate attended the Coronation Concert in a scarlet Alexander McQueen ensemble she previously wore for a Shaping Us pre-campaign launch event last January. She accessorized the outfit with a silver necklace from Van Cleef & Arpels featuring several floral pendants of various sizes. The rest of the Wales family coordinated in white and navy ensembles, with all members of the family (except Prince Louis, who did not attend) sporting the colors of the U.K. flag.
