“This was the first time we saw his little brother Louis wear a blazer and tie in public, and the fact that the Princess of Wales chose sky blue rather than navy made the outfit more fun and age-appropriate,” Riley told PEOPLE at the time. “He also matched perfectly with his mother and sister, something which he can still do as the youngest sibling.”

As for this weekend’s festivities, Prince Louis joined his two older siblings — and sat in the middle of them — during the carriage ride for his grandfather’s first official birthday parade. The trio showed off their royal waves as they greeted thousands of well-wishers lining the grand, tree-lined and flag-bedecked Mall.

The red color coordination was a nod to William and Kate’s new roles as the Prince and Princess of Wales. Kate wore green, and together the family represented the colors of the Welsh flag.
