Lime Green Outfit and Orchid Trimmed Hat for 90th Birthday Celebrations

On 21 April 2016, the day of her 90th birthday, the Queen debuted a new hat and coat for the celebrations in Windsor, designed by trusted personal dresser Angela Kelly and described by Buckingham Palace as a “spring grass green wool and silk weave coat and dress with hat to match adorned with flowers”.
The coat is collarless and has hidden buttons and flap pockets. The hat is made of white straw trimmed with the same silk mix fabric as the rest of the outfit and a spray of white silk orchids.
The Queen accessorized with the diamond Jardine Star brooch and swapped the hat for a simple white silk scarf for the beacon lighting ceremony at dusk outside Windsor Castle (Daily Mail articles here and here):
