Parade! The royal family marched through London on June 17 for the annual Trooping the Colour ceremony. Kate Middleton and Prince William were a picture-perfect family at Queen Elizabeth's celebration, greeting the public on the Buckingham Palace balcony. Along with their children, the pair looked out at the crowd with pure joy. Two-year-old Princess Charlotte, who matched her mom in a sweet pink polka dot dress, was giddy at the sight of the crowd and happy to be in her mother's arms. Three-year-old Prince George, who looked cute in a cream button-down Peter Pan collar shirt with piping detail to the sleeves and tailored shorts, also appeared in good spirits. Prince William's attire matched his son's red braces, and was awfully similar to that of his wedding day. Photo: DMC/GC Images

At the start of the event, Queen Elizabeth held a moment of silence, to honor the victims of the Grenfell Tower fire in West London, along with those killed in the UK terror attacks in London and Manchester. The 91-year-old monarch and her 96-year-old husband Prince Philip, rode through the crowds in a carriage. The Queen used to ride on horseback and trot through through the parade, but she later chose to ride in a carriage. Trooping the Colour marks the formal celebration of the her birthday, despite her actual day of birth being April 21. More than 1,400 officers take part annually as well as 200 horses and over 400 musicians from ten bands. The Queen has never missed the occasion. Photo: Getty Images
