The 33-year-old Duchess of Cambridge wore a purple jacket and matching over-the-knee fit-and-flare skirt, paired with black tights and boots and a matching hat.
She, William, 33, his younger brother Prince Harry, 31, and their father Prince Charles, 67, were seen heading into a St. Mary Magdalene Church near the Sandringham Estate, Queen Elizabeth II's country home.
The family had attended services there on Christmas Day as well. At the time, Kate bundled up in a long, green, belted coat.
