Princess Catherine defied tradition this Christmas by opting for a chic navy ensemble instead of the usual festive colors of red and green.

The Princess of Wales looked poised and perfect as she attended the Christmas Day church service at Sandringham.

Her outfit choice was a failsafe combination of a smart belted coat with a nipped-in waist and a chic collar.

Underneath, she wore a cozy roll-neck jumper to ward off the December chill.

Completing her look was a flowing skirt with tidy pleats.

To complement her dark hair, Princess Catherine added a jaunty hat with arrow detailing.

She also sported suede knee-high navy boots with towering block heels.

Adding a touch of sparkle were sapphire and diamond drop earrings, which bore a striking resemblance to her engagement ring, a precious heirloom from her husband’s late mother, Princess Diana.

Accompanied by her husband Prince William and their three children, Prince George, Princess Charlotte, and Prince Louis, Princess Catherine exuded relaxation and festive cheer.

Joining them was M.I.A.

Tindall, the eldest daughter of Prince William’s cousin Zara Tindall and Mike Tindall.

M.I.A.

sweetly held hands with little Louis as they made their way from the house to the church.

It is likely that the rest of the Tindall brood, Lena and Lucas, also joined in the festivities.

The royal family gathered in full force this morning for a morning service at St Mary Magdalene before returning to Sandringham House for a festive spread.

Other members of the royal family were spotted on the walk, each dressed in an array of colors.

Princess Anne shimmered in sparkling white, while Queen Camilla opted for a more neutral shade of beige.

The occasion marked a welcome return to Sandringham for the Princess Royal, who had been unable to attend the Christmas service last year due to a cold.

As a private event, all family members are typically invited, whether they are working or non-working royals.

This year, Sarah Ferguson, the Duchess of York, accompanied the royal family to St Mary Magdalene, marking her first attendance in over 30 years since her separation from Prince Andrew.

Following the breakdown of the Duke and Duchess of York’s marriage, Fergie was excluded from royal gatherings for several years, even during Christmas and when her daughters, Princess Beatrice and Princess Eugenie, were present.

Her presence this year signals a significant reconciliation within the family.
