White's is one of London’s oldest and most prestigious gentlemen’s clubs, established in 1693. Known for its exclusivity and traditional English charm, it has been associated with high society and aristocracy. While specific details about White's involvement at Ascot are less publicized, its members are often part of the social elite present at the Royal Enclosure during the races.

Another iconic gentlemen's club, Buck's Club, established in 1919, is famous for creating the Buck's Fizz cocktail. Its members are typically part of the British upper class and are frequent attendees of Royal Ascot. The club's presence adds to the prestigious atmosphere of the event.

The Royal Enclosure is the most exclusive area at Royal Ascot, requiring either a membership or an invitation from a current member. Entry is highly restricted, and members adhere to a strict dress code, maintaining the tradition and decorum of the event.

Royal Ascot is not just a premier racing event but a significant social occasion for the elite. Clubs like the Hong Kong Jockey Club and the Royal Ascot Racing Club epitomize this exclusivity, providing members with unparalleled access and experiences. These clubs, along with the storied traditions of White's and Buck's Club, contribute to the unique allure of Royal Ascot, making it a hallmark of British high society.
