People Editorial Guidelines Published on June 23, 2022 01:00 PM Share Tweet Pin Email Kate Middleton and Prince William are starring in their first official joint portrait, and Kate takes a style cue from none other than Carrie Bradshaw for the occasion. On Thursday, the Duke and Duchess of Cambridge stopped by the University of Cambridge's Fitzwilliam Museum to see the painted artwork as it was unveiled to the public for the first time. Commissioned in 2021 by the Cambridgeshire Royal Portrait Fund, the portrait of the couple was painted by award-winning British portrait artist Jamie Coreth. "It has been the most extraordinary privilege of my life to be chosen to paint this picture," Coreth said. "I wanted to show Their Royal Highnesses in a manner where they appeared both relaxed and approachable, as well as elegant and dignified." Duchess of Style!

For her footwear, Kate sports Manolo Blahnik's Hangisi Green Satin 105 Pumps — the same pair of shoes that Sarah Jessica Parker's character wore in Sex and the City for her wedding to Mr. Big. However, Carrie Bradshaw opted for the heels, which feature a square crystal buckle adorning the pointy toe, in a different color as her "something blue" for the big walk down the aisle.

The shimmering outfit is by The Vampire's Wife, a brand that's also a favorite of Princess Beatrice's.

(Prince William and Kate received the titles of Duke and Duchess of Cambridge from Queen Elizabeth on their wedding day in April 2011.) The brooch features a large pearl surrounded by a cluster of diamonds. There is also a detachable diamond and pearl pendant suspended from the main piece. According to The Court Jeweller, the piece was likely made by Garrard at some point in the middle of the nineteenth century. It was named for Princess Augusta of Hesse-Kassel, the wife of Prince Adolphus, who wore the piece in a portrait commissioned by her niece Queen Victoria in 1877.

Queen Elizabeth inherited the stunning piece from her grandmother in 1953 and has worn it on a number of occasions over the decades, including for her official 50th birthday portraits. The monarch also wore the brooch at the funeral of Lord Mountbatten in 1979, at the opening of the Thames Flood Barrier in 1984 and during the Golden Jubilee tour of Australia in 2002.
