Prince Charles, 69, and his wife Camilla, Duchess of Cornwall, 70, attended the annual Not Forgotten Association Garden Party at Buckingham Palace on Tuesday afternoon.
The Royal couple arrived in the June sunshine for the traditional event to welcome ex-servicemen and women from across the British Army, Royal Navy and Royal Air Force.
The Duchess of Cornwall, looked radiant at the Royal event in an elegant blue coat dress with pocket and shoulder detailing and a cream hat. She teemed her look with a pair of nude heels and white gloves.
Also in attendance at the Royal residence was the Princess Royal, 67. Princess Anne wore a gold and grey dress and evening jacket with a matching hat and was seen talking to guests in the garden.
The Not Forgotten Association charity, of which the Princess Royal is the current patron, provides entertainment, leisure and recreation for ex-service men and women with disabilities and for serving wounded, injured or sick.
