For the first time in three years, the royals will be heading to Sandringham for a big family Christmas.
The Covid pandemic meant the Firm celebrated separately for the past two years but King Charles is set to bring them all together again for the festive season. It will of course be tinged with sadness as it is the first Christmas since the death of the Queen - although it is thought Charles will keep many traditions in place, including the annual walk to church on December 25.
And royal fans will be keeping their fingers crossed that they get a glimpse of the new Prince and Princess of Wales and their three children Prince George, Princess Charlotte and Prince Louis.
During their appearance three years ago, Kate colour-coordinated the family's outfits, and they all looked very smart in dark green.
And while fans around the world loved their style, it turns out that Kate really regretted her outfit choice for the day, and even told one well-wisher she "really shouldn't have worn it".
She looked stunning in a heavy grey Catherine Walker coat, with a green hat, bag and heels.
But during a quick chat with 19-year-old fan Rachel Anvil, she admitted it was the wrong choice for the unseasonably warm weather.
Rachel's mum told Metro : "Kate was talking to my daughter about clothes and how she was feeling too hot, she said 'I really shouldn’t have worn this'.
"I’m there talking to Charlotte about dolls and my daughter’s talking about fashion with Kate.
"It wasn’t fake it was a genuine discussion, it was about a minute but it was tailored to my daughter, it was like speaking to a friend."
Royal Christmases usually feature a morning trip to St Mary Magdalene Church, the greeting of well-wishers, and a family lunch with turkey and all the trimmings.
Charles is also preparing to pre-record his historic, first-ever Christmas Broadcast as monarch when he will no doubt reflect on the loss of his mother and her legacy.
Traditionally, members of the royal family sit down to watch the televised address when it airs after lunch, usually at 3pm on December 25.
Meanwhile, Windsor Castle has already been transformed ready for Christmas, with a 20ft tree in St George’s Hall decorated with 3,000 lights and hundreds of regal purple ribbons.
It took a team of four staff from the Royal Collection Trust two days to dress the Berkshire royal residence’s festive trees.
Tourists visiting the State Apartments will see shimmering trees, twinkling lights and festive garlands.
