Kate Middleton and Prince William Bring 3 Children to Easter Church Outing — All Coordinated in Blue!

Kate Middleton and Prince William are making their Easter debut — both as the Prince and Princess of Wales and with all three of their children!

The couple stepped out alongside other members of the royal family for the Easter church service at St. George's Chapel in Windsor Castle on Sunday. For the first time, they made the holiday outing as a family of five — although Prince George, 9, and Princess Charlotte, 7, joined their parents at the event in 2022, 4-year-old Prince Louis also tagged along for the Easter service this year.

The Wales family coordinated in blue ensembles, which was also the color of choice for King Charles and Queen Camilla for the church visit. Blue seems to be a go-to color for Prince William and Princess Kate for family portraits, who also dressed in the color for their 2022 Christmas card and last year's Trooping the Colour parade.

Princess Kate wore a Catherine Walker & Co coat dress that she previously wore at the 2022 Commonwealth Day Service, and completed the look with a blue version of her Lock & Co pillbox hat that she wore last year for St. Patricks Day. And although she normally favors neutral nail polish colors, Kate opted for a bold red shade for the Easter outing.

Princess Charlotte sported a floral dress British children's wear designer Rachel Riley with blue tights under a navy coat. After the church service, Charlotte ditched her coat — and Kate was seen carrying it as they walked away from St. George's Chapel.

While Prince William and Prince George matched in suits and ties, Prince Louis rocked shorts by Rachel Riley with a tie and blazer. It's typical for upper-class boys in Britain to wear shorts in their younger years, and Louis' big brother was known for his shorts and knee socks until recent years when he switched to suits.

All three of Prince William and Princess Kate's children showed off their handshakes while leaving the church service, greeting the pastor with the gesture.

Prince Louis' Easter debut came just a few months after he joined the royals at their Christmas Day church outing for the first time.

Prince George and Princess Charlotte are quickly becoming pros at traditional royal events. The two eldest Wales kids are now old enough to join the family at many outings, including the Christmas walk, a memorial service for their great-grandfather Prince Philip in March 2022 and the funeral for their great-grandmother Queen Elizabeth in September.

It was recently announced that Prince George will have a big role at his grandfather King Charles' upcoming coronation on May 6. The young royal, who is second in line to the throne, is set to be a page for the King at the historic ceremony.

"His parents are very excited and delighted that he is a page," a spokesperson for the Prince and Princess of Wales tells PEOPLE. "It's something that his parents have thought long and hard about and are very much looking forward to — and I'm sure George is, too."

Kate, 41, and Prince William, 40, have shared that their children previously celebrated Easter with an egg hunt.

And in 2020, the royal couple conducted their first-ever full royal engagement via video call amid the coronavirus pandemic, chatting with a school in northern England. Towards the end of the call, the staff made sure to wish them a happy Easter, and Prince William assured them that they will be celebrating with plenty of candy.

"There will be a lot of chocolate being eaten here, don't worry!" he said.

Then Kate turned to her husband with a laugh and quipped, "You keep eating it!"

It's already been a big weekend for Prince George, who made a surprise outing with Prince William on Saturday at the Aston Villa soccer game. The father and son watched the match intensely, often sporting mirroring expressions as they followed the action.

King Charles and Queen Camilla led the Easter celebrations for the first time in the new reign. However, the service will likely be bittersweet for the royal family. This Easter marks the first without Queen Elizabeth, who died in September at age 96, and her funeral was likely the last time the family was at St. George's Chapel together. The late monarch, who served as the ceremonial head of the Church of England for the 70 years of her reign, is buried nearby in the King George VI Memorial Chapel.
