The Duchess of Cambridge, 40, wowed in a custom Emilia Wickstead yellow dress when at the ceremony, while later that day, Princess Anne sported a bright red blazer while visiting Edinburgh Zoo as part of the Queen's Platinum Jubilee celebrations. From Princess Eugenie's £1,503 orange dress from Emilia Wickstead to Zara Tindall's Laura Green hot pink frock for the Service of Thanksgiving for the Queen on Friday, Her Majesty's support squad of royal women made sure their fashion choices were just as vibrant as the monarch's usually are.
