See Queen Elizabeth, Kate Middleton, and Prince William at the Queen's Annual Garden Party

Every year, Queen Elizabeth hosts thousands of lucky guests for a series of garden parties-three on the grounds of Buckingham Palace, and one at Holyrood House. (Although, as was the case earlier this month, sometimes other senior royals will host them in the Queen's place.) The parties have been a mainstay on the royal calendar for well over a century.

Today, the Queen kept up the tradition with yet another garden party, attended by a whopping 8,000 people, per royal reporter Rebecca English. Here, all the best photos from the event.
