Kate Middleton recycles the £1,350 Miu Miu festive cardigan she also wore for the 2021 'Together at Christmas' carol tea party

The Princess of Wales showed her love of sustainable clothing as she surprised adults who work in childcare at a special set for her Together at Christmas service.

Kate, 41, attended a surprise celebratory tea party in honor of children's carers wearing a £1,350 red Miu Miu cardigan – and it's not the first time we've seen it – she showed off the knitwear for the first time in the promotional video before their 2021 Christmas carol concert.

The mother-of-three completed her ensemble this time with matching red pants and pearl earrings from Cassandra Goad, while her auburn locks were styled in her signature loose waves.

Kate's luxurious cashmere jacquard cardigan features a diamond pattern decorated with white and black roses, complemented by a detachable cotton collar.

Despite its high price, the design proved a huge hit with the princess's followers and sold out soon after its initial appearance.

The cashmere garment from Italian label Miu Miu features an attractive diamond stitch in a perfectly matching scarlet colorway.

The Peter Pan collar is removable and the white roses woven from jacquard on the back give the look even more festive flair.

Kate debuted the cardigan in 2021 while helping decorate Westminster Abbey ahead of her Together at Christmas service.

She skillfully styled the design with black wide-leg trousers by Roland Mouret and heart-shaped earrings by Kiki McDonough.

Just days after the shot was released, the item sold out in all sizes on the Miu Miu website, as well as at Net-A-Porter and Farfetch.

The queen is a long-time fan of the Italian brand and not only owns the cardigan, but also a tartan coat and a red bow clutch, which she has worn frequently since 2016.

Yesterday, Kate surprised three busy childcare adults with a Christmas tea party – in a special performance that will be broadcast tomorrow as part of the royal's Together at Christmas carol service.

After a joyful reunion between the adults and the children they had been caring for, the princess came through a side door to surprise them, saying, “I'm sorry to interrupt the party, I hope you don't mind.” !”

First photos from the heartwarming clip show Brenda, a retired mental health nurse from Sussex who volunteers at a local school, holding the princess' hand as the couple enjoy a lively conversation.

Kate also met brothers George and Henry Barnard, aged 12 and 10, who have benefited from music therapy at the East Anglia Children's Hospice, of which Kate is a patron.

The royal spoke to the brothers for fifteen minutes about their love of music, saying that Prince George loves playing the guitar, Princess Charlotte loves singing and Prince Louis is a fan of the drums.

The princess then presented the boys with “beautifully wrapped presents,” which they saved for Christmas Day.

She also heard from Ray, a music therapist from East Anglia Children's Hospice (EACH), who provided music therapy and support to a family after their baby boy was diagnosed with spinal muscular atrophy at 18 months old.

Meanwhile, Russell, a football coach from his childhood in Manchester, helped a child by boosting his confidence and enabling him to pursue his passion for football.

Speaking about the surprise royal visit, he recalled: “It was just breathtaking.” “She took the air out of the room.”

The special was filmed in London last month.
