The newly-minted Duchess of Cornwall and Cambridge, 40, looked somber as she drove through Windsor, England on Friday, emerging for the first time since Queen Elizabeth’s death. The royal looked sultry in sunglasses and a black turtleneck, paired with pearl earrings. Kate did not join her husband Prince William on the trip north to Balmoral Castle in Scotland on Thursday, where the Queen has been on summer vacation since July. After announcing that her doctors were “concerned” about her health, Buckingham Palace said in a simple statement that the 96-year-old monarch died “peacefully” at her beloved Balmoral on Thursday afternoon local time. While William was joined by Prince Andrew, Prince Edward and Sophie, Countess of Wessex, they rushed to Her Majesty’s bedside, where they met Prince Charles (now King Charles III), Princess Anne and later Prince Harry in the castle. Kate probably stayed behind for their children’s first day of school.
