Kate Middleton was the only royal without a sash at the state banquet

But why?

Words by Jadie Troy-Pryde

Prince George might be getting ready to start school in September, but before he lays out his uniform he's off on a trip to Europe with Prince William and Kate Middleton. The little royal is currently on tour with his parents and his little sister, Prince Charlotte, as the family attempts to smooth over relations with the EU leaders following last year's Brexit referendum.

Before the family made their way to Poland and Germany, the royals welcomed Queen Letitia of Spain to Buckingham palace. It was the first time that Prince Harry had an official role during a state visit, and the monarchs sat down for a state banquet which was - as expected - a glamorous and opulent affair.

But while everybody was fawning over Kate's Marchesa gown and the stunning royal heirloom that hasn't been seen in public for thirty years, everybody failed to notice one small detail about the Duchess of Cambridge's outfit. While all the other royals in attendance at the dinner wore a regal sash, Kate went without one.

While the Queen, Duke of Edinburgh, Prince Charles, the Duchess of Cornwall, Prince William and Princess Anne - as well as the King and Queen of Spain - were all spotted wearing the royal accessory, Kate was not.

Why? The reason happens to be more of a royal rule than a sartorial snub from Kate.

According to tradition, one must be part of an Order for the luxury, and it just so happens that as of yet, Kate is not. There are many 'orders', the most famous being the Order of the Garter.

The official Palace website states: 'In medieval times, King Edward III was so inspired by tales of King Arthur and the chivalry of the Knights of the Round Table that he set up his own group of honourable knights, called the Order of the Garter. Nearly 700 years later, the Order is the oldest and most senior Order of Chivalry in Britain.'

While the Queen is Sovereign of the Garter, and other members include Prince William, Kate has not received the honour of an order just yet.

However, it is thought that the Duchess of Cambridge will be appointed in the next few years - so sit tight Kate, a sash should be coming to you soon...
