Her cashmere-jacquard cardigan featured a diamond-patterned design embellished with white and black rose motifs, finished with a detachable cotton collar – this added a refined, vintage-inspired touch.

Reaction online was swift once the price of the cardigan became public. Social media users took to X, formerly Twitter, to share their thoughts, with one commenter writing: “A sweater for £1,350?!” while another added: “She looks wonderful, but that price is hard to justify.”

Catherine paired the cardigan with a matching red skirt, and styled her long chestnut hair in her signature loose waves.

Unsurprisingly, the cardigan quickly sold out following her appearance, disappearing not only from Miu Miu’s own website but also from luxury retailers including Net-A-Porter and Farfetch.

Meanwhile, the Princess of Wales was first seen wearing the piece during the filmed introduction for the 2021 Together at Christmas concert.

She later revived the statement piece in 2023, re-wearing it for a festive tea party connected to the same seasonal project, reinforcing her continued commitment to meaningful dressing.
