William, Kate and Harry join the Queen at church in Sandringham

The Queen had some special company at church on Sunday (Dec. 27). Prince William, the Duchess of Cambridge and Prince Harry joined the monarch for the traditional post-Christmas event. Dressed in a tweed jacket and skirt, Kate smiled and waved as she walked to the church, while her children Prince George and Princess Charlotte avoided the cold weather by staying at home.

The mother of two was particularly delighted when she received a bouquet of yellow flowers from well wishers.

Prince Harry followed closely behind the royal couple, wearing a long navy coat with a pale blue shirt and matching tie. The young royals were joined in the church by the Queen, who arrived by car. Her Majesty opted for a long cream jacket with chain detailing around the seams, and a matching cream and black hat.

On Christmas day, the royals attended the same church for a special festive service. The Duchess of Cambridge looked impeccable for the religious ceremony, wearing a Great Plains patterned dress under a long moss green belted coat from Sportmax. On her lapel the 33-year-old pinned an oak leaf and acorn brooch, a representation of the Middletons’ coat of arms.

Accessorizing the look Kate wore a dark green Lock and Co hat, black Aquatalia boots and carried a Mulberry clutch bag.

After the service Prince George’s parents rushed back to see their two children and to host Christmas lunch for Kate’s side of the family. Her parents, Carole and Michael Middleton were invited to Anmer Hall with Kate’s siblings James and Pippa to share the special day with the family of four.
