The Royal Family are out in full force today to kick off celebrations for The Queen's Platinum Jubilee - marking 70 years of Queen Elizabeth II on the throne.
The four-day extravaganza begins with the Trooping The Colour parade and as part of this, The Duchess of Cambridge, The Duchess of Cornwall and George, Charlotte and Louis rode in a carriage down the Mall.
All five of them were dressed very sharply, but reagle-eyed viewers were particularly intrigued by the outfit the youngest royal was wearing.
