For the royal family's attendance at the Church of St. Mary Magdalene's Christmas service, Kate wore a brown plaid Blazé Milano coat, complete with a patterned scarf and a brown Juliette Botterill Millinery fascinator. It wasn't Kate's first time wearing the coat this year—and the first occasion marked a special day for her.

Princess Kate's 10-year-old daughter, Princess Charlotte, played the piano at her mother's side in a pre-recorded portion of the televised concert at Westminster Abbey. The royal duo performed "Holm Sound" by Erland Cooper during "Royal Carols: Together at Christmas."

Princess Charlotte joined Princess Kate for a royal duet on Christmas Eve as part of the special "Royal Carols: Together at Christmas."

Princess Charlotte's "rare" royal style was praised in a viral TikTok post in which fans said she would make a good queen were the crown not destined for her older brother, Prince George. Charlotte is Prince William and Princess Kate's second child and has already won many royal fans aged just 10 years old.

After years clocking in at the top of the official royal act list, Princess Anne has been bumped to second place.

Princess Diana adored the spirit of Christmas, but she often struggled with some royal traditions. In fact, there was one element of the celebration that weighed on her deeply.

Among the extended Windsor clan attending church at St. Mary Magdalene on Christmas morning today were Princess Margaret’s son, David Armstrong-Jones, and his children, Lady Margarita Armstrong-Jones and Charles Armstrong-Jones, Viscount Linley.
