The final stop of the Duke and Duchess of Cambridge's Royal Train tour was Windsor Castle for a family reunion at The Queen's current residence.
William and Kate greeted their granny upon arrival.
The Duke and Duchess of Cambridge joined The Queen, Prince Charles, The Duchess of Cornwall, The Earl and Countess of Wessex, and Princess Anne to welcome essential workers.
The royal family met local volunteers and key workers from organisations and charities in Berkshire, who will be volunteering or working to help others over the Christmas period.
For the closing outfit of the tour, the Duchess brought back the forest green Catherine Walker double-breasted coat.
The custom coat was first worn earlier this year where is made a stately debut during the royal visit to the Republic of Ireland.
Kate layered the midi coat with a tonal faux fur lapel collar by Troy London (£65).
Kate opted to carry a minaudière, bringing back the black velvet box clutch by Alexander McQueen.
First spotted at last year's Festival of Remembrance, the custom clutch combines the body of the designer's Beetle Box clutch and the jewel clasp seen on the Mini Crystal-Embellished Leather Bag.
The Cornelia James 'Alice' Merino Wool Gloves were also worn again.
The Duchess completed the yuletide look with Queen Elizabeth II's diamond orbital teardrop earrings - believed to be on permanent loan from Her Majesty.
I'll conclude with a photo of The Queen looking particularly festive in red.
