Although Kate was likely behind Charlotte's last-minute style - the royal mom showed off her braiding skills when she and William visited Northern Ireland's Cinemagic, a charity that uses film, television and digital technologies to help more than 500,000 young people, in February - Prince William has been upping his own styling game.
Trooping the Colour has marked the official birthday of the British Sovereign for over 260 years. She was all smiles during the event, wearing a navy Givenchy outfit by her wedding dress designer, Clare Waight Keller, and a matching navy hat by Noel Stewart.
And there were plenty of royals on the Buckingham Palace balcony, so much so that there was hardly space for the Duke and Duchess of Sussex, who were amongst the last to emerge.
The Duke and Duchess of Sussex had released three official wedding pictures to the public after their nuptials in May 2018.
Meghan, 37, is now on maternity leave following the birth of son Archie in May but took time off to join Prince Harry, 34, and other senior royals at the Buckingham Palace engagement on Saturday.
Meghan made one of her first official royal engagements at the Trooping a year ago after marrying Prince Harry last May. Prince Charles, Prince William, Kate Middleton, Prince Harry and Meghan Markle were all in attendance.
He was joined by Princess Charlotte and Prince George who looked on as the Red Arrows flew overhead.
Princess Charlotte changed up her look in the middle of Trooping the Colour - and we nearly missed it!
Harry and Meghan welcomed their first child, son Archie Harrison Mountbatten-Windsor, on May 6.
