June 19th 2012 - the opening day of Royal Ascot, the annual horse races in Berkshire. The Queen leads the royal carriage procession in a lovely blue outfit with the brooch that is now part of the Brazilian Aquamarine parure.
Wearing a beautiful dove-grey coat over a white linen shift by Catherine Walker, Princess Diana wowed them at Ascot Racecourse. A white hat by Philip Somerville completed the outfit. This dress and coat ensemble is one of Princess Diana’s best looks and a great example of why she was always at the top of the best dressed list.
