Queen Camilla looked the epitome of elegance on Saturday as she attended Trooping the Colour in a red silk coat dress with a Philip Treacey hat.
The monarch looked so regal in the Fiona Clare Aldridge floor-length silk gown, which takes inspiration from the Grenadier Guards' uniform. Camilla assumed the position of Colonel of The Grenadier in December.
The royal's symbolic dress incorporated key details from the uniform, including the 'The Grenade Fired Proper' embroidered in gold bullion on the collar and the gold bullion back slashes. Camilla accessorised with a black beret-style cap with a feather plume, in a nod to the bearskins that the regiment wear.
Camilla accessoried with a pair of gold drop earrings, wearing her hair in her signature blowed-out style. As for her makeup, Camilla opted for a flutter of black mascara and rosy blush and a pink lip.
Queen Camilla arrived by carriage alongside the Princess of Wales, who looked spectacular in a green maxi dress, along with the Prince and Princess of Wales' three children, Prince George, Princess Charlotte and Prince Louis.

King Charles III arrived on horseback, wearing the tunic of the Guard of Honour Order, the Welsh Guards.
The King's uniform bore the cypher of his mother, Queen Elizabeth II, as the tradition is that the uniform of the monarch bears the cypher of their predecessor.
King Charles and King Camilla were joined by the likes of the Prince and Princess of Wales, the Princess Royal, and the Duke and Duchess of Edinburgh for the royal event in central London.
In a milestone moment for Charles, the event marks Charles' first official birthday parade of his reign, since his accession to the throne last September.
