GB News called Prince Louis's Trooping the Colour appearance a "subtle transition," with the royal essentially debuting a "new look" by perfectly twinning with Prince George. "Prince Louis marked a significant departure from previous years," the outlet reported, while also stating that the royal's "choice breaks with a longstanding custom."

Prince George, Princess Charlotte and Prince Louis made an appearance on the Buckingham Palace balcony for Trooping the Colour. See the best photos of the royal siblings.

It’s no secret that Prince William and Kate Middleton have built a close-knit family over the years. But their three children — Prince George, Princess Charlotte and Prince Louis — appear to share an even stronger bond than the cameras usually reveal.
