In particular, they wanted to thank the group for supporting the large crowds that gathered in Windsor to commemorate the Queen and watch the procession of her coffin up the Long Walk to the castle ahead of the service.
As per royal mourning guidelines, the royal couple appeared in black as a show of respect for the late Queen who passed away on 8 September. Kate looked particularly chic in a tailored black coat adorned with gold buttons, black heels and pearl drop earrings.

Prince William, meanwhile, opted to wear a smart navy suit and black tie. Members of the royal family will continue to observe the royal mourning period until Monday 26.
Their Windsor outing comes after William and Kate made an appearance at Her Majesty's incredibly moving state funeral held in Westminster Abbey. A sombre-looking Prince William wore his military uniform as he joined the procession walking behind the Queen's coffin.

Also in attendance were the Queen's children – King Charles, Princess Anne, Prince Andrew and Prince Edward – and their partners, the Queen Consort, Vice Admiral Timothy Laurence and the Countess of Wessex.
Although a sad time for the family, the Queen has now been reunited with her beloved husband, Prince Philip, as well as her family, King George VI, the Queen Mother and Princess Margaret.
