And in previous years, eagle-eyed royal fans have been quick to notice that a number of family members, including Lady Louise Windsor and Princess Anne, were wearing the same scarf for the infamous walk.

And it turns out that we may see the scarf again today – as there is a very touching reason behind the matching accessory.

The beige and grey scarf is the ‘Prince of Wales Highgrove Heritage Scarf’, which was created in a collaboration between King Charles’ Highgrove residence, The Prince’s Foundation and woollen mill Johnstons of Elgin.

It is sustainability sourced with 100% ultrafine Responsible Wool Standard merino wool from Australia.

Not only this, but the material features the “iconic Prince of Wales check” woven over an enlarged Shepherd check.

On Christmas Day last year, at least five royals donned the scarf, with Princess Anne and husband Timothy Laurance wearing it with their coats.

Prince Edward’s daughter Lady Louise, now 21, looked smart as she paired the scarf with a navy coat.

Princess Margaret‘s grandson Samuel Chatto, now 28, and Princess Margaret‘s son, Earl of Snowdon, 63, also wore the winter accessory.

Many royal fans also speculated that the matching scarf could have been a gift from King Charles to his family.

Luckily for royal fans, it turns out that anyone can get their hands on this stunning scarf, which we are sure to see worn by a number of royals today.

It is currently being sold on the Highgrove Garden website for a jaw-dropping £150.

The website states: “The Highgrove Heritage Scarf’ launched in early October in time for The Campaign for Wool’s 11th anniversary and coincided with the London Craft Week where it had its debut.

“The Shepherd check was originally coloured from undyed wool using a colour palette of black, dark browns and whites.

“Both designs have been incorporated into this modern interpretation, along with the introduction of a warm honey colour inspired by the Highgrove Gardens and a bee emblem that has been part of the Johnstons of Elgin company since the 1930s.

“The bee represents the mills’ busy workforce, which currently stands at 1,000 people. From apprentices to artisans and innovators, all have been honing these rare textile skills for over 40 years.”

A royal Christmas

Last year’s Christmas Day was a private, intimate gathering for the royal family.

After their walk and church service, the royals headed back to Sandringham for a traditional Christmas dinner.

Typically, the family’s Christmas Day celebrations at Sandringham begin with breakfast.

Former chef to the Queen Darren McGrady revealed that some members of the family have a full English – but that “married women” have something lighter brought up to their rooms.

Christmas lunch includes “salad with shrimp or lobster” followed by turkeys and Christmas pudding.

And today, after their lunch, the royals are expected to gather in a very opulent room inside Sandringham House.

The royals will gather to relax and watch King Charles’ speech, which will air on BBC, ITV and Sky News from 3pm and will last for around 10 minutes.

Whilst the royals will relax in the afternoon, they will of course stand for the National Anthem.
