This morning, members of the royal family gathered in Windsor to take part in centuries-old tradition known as Garter Day. The ceremony honors the Order of the Garter, which is the "oldest and most senior Order of Chivalry in Britain," and was established by King Edward III almost 700 years ago.
The Queen and several of her relatives including Princes William, Charles, Andrew, and Edward, Princesses Anne and Alexandra, and the other Knights, both men and women recognized for their public service, processed in to Windsor Castle in ceremonial dress.
The Knights' spouses are also there to watch the procession, which is why the Duchess of Cambridge was on-hand in Windsor this morning.
Kate chose a white collared dress with black piping for the occasion, which she paired with a black hat, pearl earrings, and black pumps.
Other royal wives at this today's events included Camilla, the Duchess of Cornwall and Sophie, the Countess of Wessex, as well as foreign royals like Queen Maxima of the Netherlands and Queen Letizia of Spain, whose husbands were invested as Supernumerary Knights of the Garter this morning.
It's already been a busy day for the Duchess of Cambridge. In addition to her appearance in Windsor, she also shared a letter of support for Children’s Hospice Week this morning.
"Children’s hospices provide vital sanctuaries for those experiencing the very toughest of times. They help families and carers build life long memories that are poignant, happy and often filled with laughter," she wrote.
"They provide a lifeline to children and families for however long support is needed and I hope that others join me in thanking them as we shine a light on their work during Children's Hospice Week."
