What is Garter Day? And why does the British royal family celebrate it?

Kate Middleton wore a look - worthy of any bride - for the Garter Day celebrations, which take place this Monday, June 16, in London.

Together with her husband, Prince William, the Princess of Wales attended a religious ceremony at St. George's Chapel, Windsor Castle, where she traveled by carriage, as you can see in the images in the gallery .

For the occasion, Kate dazzled in a white outfit by Self-Portrait, consisting of a blazer and a skirt with lace appliqués. The hat, for a final touch of sophistication, was by Sean Barrett. The shoes, stilleto style, were by Gianvito Rossi (as usual) and the bag by Strathberry.

In terms of jewelry, Kate dazzled with a pearl necklace by Susan Caplan that she paired with earrings, also made of pearls.

William wore traditional attire, as he is one of the knights of the Order.

What is Garter Day?

Garter Day is a celebration in honour of the Order of the Garter (the oldest Order of Chivalry in the United Kingdom), and therefore ladies and knights are seen dressed up for the official celebrations - which take place annually.

The Order was founded by King Edward III almost 700 years ago, inspired by the exploits of King Arthur. Knights, both men and women, were originally members of the aristocracy, but today they can come from all walks of life, given their public service.

Members of the Order of the Garter

From the British Royal Family:

King Charles III, Queen Camilla, Prince Edward, Duke of Edinburgh, Princess Anne, Prince Richard, Duke of Gloucester, Princess Alexandra, Prince Andrew, Duke of York, Prince Edward, Duke of Kent

Prince William

From foreign royal families:

Margrethe II, Queen of DenmarkCharles Gustaf, King of SwedenKing Juan Carlos of SpainPrincess Beatrix of the NetherlandsEmperor Akihito of JapanHarald V, King of NorwayFelipe VI, King of Spain

Willem-Alexander, King of the Netherlands

This group is joined by other names, outside the aristocracy, who became part of the Order due to their achievements, such as Tony Blair, former British Prime Minister.

Knights are chosen by the English monarch, in this case Charles III. The investitures take place in the Throne Room at Windsor. The Order is composed of the sovereign, the Prince of Wales (William) and 24 members (although there are supernumerary members).
