Kate Middleton epitomizes simple elegance in an embroidered dress and the Queen Mother’s tiara

We don’t often get to see the Princess of Wales in a tiara, but a state banquet today provided the perfect opportunity for Princess Kate to remove a dazzling piece from the royal archives.

Kate and her husband Prince William were among those attending King Charles III’s State Banquet this evening at Buckingham Palace, held in honor of the arrival of Yoon Suk Yeol, President of the Republic of Korea, and Kim Keon Hee, first lady of the country.

The special occasion allowed Kate to showcase a rare tiara look. The royal family’s website describes state banquets as “a very large formal occasion held in the ballroom of Buckingham Palace,” which is why royal women often choose to wear a tiara for such events.

Kate opted for the Strathmore Rose Tiara, a diamond-encrusted floral tiara that once belonged to the Queen Mother. Last year, an expert contacted by Express estimated the value of the sparkler at around half a million pounds.

The headpiece was an elegant complement to the rest of the princess’s ensemble, which consisted of a white Jenny Packham dress with gold-embroidered cape sleeves, white opera gloves and diamond earrings.

Earlier today, Kate joined William, Charles and Queen Camilla to welcome Koreans to London in an official ceremony at London’s Horse Guards Parade Ground. There, she made another bold fashion statement in a monochrome festive outfit. This included a Catherine Walker coat dress awash in bright candy apple red, crimson suede pumps by Gianvito Rossi, a wide-brimmed red hat and a rectangular red shoulder bag with a small bow, from Miu Miu.
