The King and Queen were on good form as they welcomed guests to the first Buckingham Palace garden party of the year.
In the middle of a busy week to mark VE Day commemorations, Charles, 76, and Camilla, 77, stepped out to mingle with attendees, who have made a positive impact in their community.
Their Majesties were joined by the Princess Royal, the Duke and Duchess of Edinburgh, and the Duke and Duchess of Gloucester for the afternoon soiree.
Upon arrival, the royals stood at the top of the garden steps to observe the national anthem, before dispersing into the crowd.

The Queen patted a guide dog, saying she was "honoured" to meet him, as she and the King hosted thousands of guests at a Buckingham Palace Garden Party.
Camilla, in a teal blue crepe dress with a cream lace insert by Christian Dior, matching hat by Philip Treacy and turquoise and diamond brooch, bent down to tickle Haworth's tummy after spotting him in the crowd.
"I've had him seven years, he's my fifth guide dog, but he's the first one to meet the Queen,” said his owner Jeanette Binns, an equalities and cohesion officer at Lancashire County Council.
"Well I'm very honoured to meet him," replied the Queen, smiling.
"He did pile it on a bit," Jeanette said of Haworth afterwards. "He knows how to impress. I've always said he's an attention seeker, he's gone up a notch with this."

The Queen also commented on a striking pair of My Little Pony shoes worn by China Morgan, yard manager at Ebony Horse Club in Brixton, South London.
"Oh look at that, very cool," said Camilla, who is President of the charity.
Sid Holdsworth, the charity's COO said: "It's really exciting to be here, we are extremely grateful for the invitation. The Queen is a very supportive President."

The King, who wore a cornflower in his buttonhole and a blue tie, stopped to chat to the Venerable James Ridge, who was appointed as a Chaplain to the King in January, and the Reverend Ruth Ridge.
He also chatted to Messenger Sergeant Major William Tuffs, of the King's Body Guard of the Yeomen of the Guard, who is retiring after a 56 year military career.
"I joined the Coldstream Guards in 1969 aged 15 and have been in the Body Guard for 28 years," he said after meeting the monarch.
During his time as a Beefeater, William participated in the funerals of the Queen Mother, Prince Philip and Queen Elizabeth, as well as King’s Coronation.
Yeomen of the Guard also provide symbolic security at events such as Garden Parties.
"It's fantastic, it's such a pleasure to work at a garden party because people here are enjoying themselves," William said.
"The King was saying about the many years I have served the Crown. He said 'enjoy your retirement'."
William, who attended with wife Ceri, also served with the Territorial Army and Bedfordshire Police and now volunteers as a lifeguard at the swimming pool at Keech Hospice Care in Luton, Bedfordshire.
What happens at palace garden parties?
Every year, the Sovereign traditionally hosts three garden parties at Buckingham Palace in London, and one at the Palace of Holyroodhouse in Scotland.
Historically, garden parties took the place of presentation parties attended by debutants, but have evolved into an event, which recognises and rewards public service.
The dress code stipulates morning dress or lounge suits for men, and day dresses for women, with hats or fascinators. National dress and uniforms can also be worn.
