It is with the utmost privilege and delight that one receives an invitation to a Royal Garden Party. Each year, a select assembly of just over 30,000 individuals is bestowed the honour of attending one of up to three garden parties hosted at the resplendent Buckingham Palace, in addition to a singular affair held at the Palace of Holyroodhouse in Edinburgh. Perpetuating a cherished tradition inaugurated by Queen Victoria in the 1860s, these garden parties serve as a means of acknowledging and celebrating those who have profoundly enriched the vitality and spirit of their communities. Such distinguished individuals are typically nominated by the Lord Lieutenant - the sovereign's personal emissary in each county - alongside the military services or local government. Naturally, the presence of a companion is warmly welcomed.

Now convened in the afternoon and spanning approximately three hours, these gatherings were once dubbed 'breakfasts' and reserved exclusively for the aristocracy. Historically, they also provided an occasion for debutantes to be presented at Court, a practice that ceased upon Queen Elizabeth II's ascension. The event is heralded and concluded by the national anthem, during which Their Majesties King Charles and Queen Camilla engage with their guests, who are encouraged to dress befitting the occasion. According to the Royal website, gentlemen are advised to don morning dress or lounge suits, whilst ladies are expected to grace the event in day dresses, adorned with hats or fascinators. National dress and uniforms are also deemed appropriate.
