The duo donned matching white outfits for Charlotte's first portraits in 2015, though George added a pop of blue to his.

For their fun play date in Canada, George and Charlotte traded in their airport looks for another pair of matching blue outfits. Charlotte donned three different shades of blue, while George spruced up his outfit with some red shorts.

On the final day of their Canadian tour, Charlotte and George looked adorable in their matching blue and red outfits.

To kick off their five-day tour of Poland and Germany in 2017, William and Kate dressed Charlotte and George in color-coordinated red and blue looks. William also joined in on the fun with his blue suit and red tie.
