The royal family stepped out in full force on Sunday for the Easter Mattins service at St. George's Chapel, Windsor Castle.
The annual service is an important fixture in the royal family's calendar. This year's service is particularly bittersweet seeing as it marks the first Easter service since Queen Elizabeth II's death.
King Charles attended the service alongside his wife Queen Consort Camilla. The duo donned matching blue outfits for the joyous ocassion, with Queen Consort Camilla wearing a dress by Anna Valentine, and His Majesty in a smart suit.
The couple were accompanied by a number of senior royals including Prince William and Princess Kate who were joined by their three children: Prince George, nine, Princess Charlotte, seven, and four-year-old Prince Louis.
Little Louis made his Easter service debut alongside his mother, the Princess of Wales. The royal tot looked so sweet in cornflower blue shorts, a navy blazer and a royal blue tie.
Princess Kate, 41, meanwhile, looked her usual polished self in a stunning cobalt blue coatdress crafted by Catherine Walker. She accessorised with nude heels, a matching blue clutch bag and a stunning pill-box hat by Lock & Co.
Princess Charlotte could be seen holding hands with her father, Prince William. The young royal was photographed casting a furtive glance at her little brother - no doubt watching out for any cheeky moments in the spotlight.
William and Kate are currently taking a break from their royal duties to spend time with their children during their Easter holidays. George, Charlotte and Louis attend Lambrook school, which is a short drive from their Windsor home, Adelaide Cottage.
The Duke of York and the Princess Royal followed behind King Charles and Camilla. The Duke and Duchess of Edinburgh, meanwhile, arrived with their son, James, the Earl of Wessex.
The newly-appointed Duchess looked elegant in a cranberry-hued coat which she paired with suede boots and an asymmetrical hat. Sublime!
Princess Beatrice and her husband, Eduardo Mapelli Mozzi, also attended the service, as did her sister Princess Eugenie and her husband, Jack Brooksbank, in addition to Zara and Mike Tindall and their two daughters, Mia and Lena.
Zara, 41, looked flawless in a vibrant pink dress which she teamed with a stunning headpiece and a pair of pointed beige heels. Princess Beatrice, 34, meanwhile, opted to wear a sophisticated dress adorned with a statement bow belt.

Following the service, Princess Kate received a delightful posy of white and yellow flowers from Samuel, eight.
While the King and the Queen have spent Easter at their Scottish residence, Birkhall, in the past, it is expected that they will host the royals in Windsor this year.
Sunday's Easter service comes after King Charles and Queen Consort Camilla attended the first Royal Maundy service of their reign. At York Minster, the monarch distributed commemorative coins, known as Maundy money, to 74 men and 74 women who have made a difference to their communities.
The money is presented to thank the recipients for their outstanding Christian service and for making a difference to the lives of people in their local communities.
