Kate Middleton Princess CharlotteTwinning is a great idea for Easter.

The Duchess and Duke of Cambridge Prince WilliamTheir children attended the Easter Sunday service at Windsor Castle for the first-time on April 17th. They attended the annual service at St George’s Chapel Windsor Castle with Charlotte (6 years old) and their oldest son, 8 years. Prince George, 8. Their youngest son, Prince LouisThe 3rd was not found.

Kate and Charlotte wore blue dresses—the duchess sported a bespoke pastel blue, knee-length Emilia Wickstead coat dress—an outfit she once sported at a 2017 visit to Luxembourg, paired with Emmy London “Rebecca Riviera” blue-gray suede pointed court pumps, while her daughter was dressed in a blue floral Rachel Riley “Forget Me Not” smocked dress, covered by a navy blue Il Porticciolo “Roberto” cardigan, and paired with light blue tights and black shoes.

William and George also swam in navy blue suits, as they were twins.

Kate and William, since the birth of their children, have been attending the Royal Easter Sunday service nearly every year on their own.
