How stunning!

Kate Middleton paid tribute to her late mother-in-law Princess Diana‘s legacy at the Buckingham Palace state banquet on Wednesday, July 12 by wearing one of her favorite tiaras.

The occasion in question was a truly royal affair. Queen Elizabeth hosted a state banquet to honor Spain’s King Felipe and Queen Letizia who are currently visiting the UK. Prince William, the Duchess of Cambridge, Prince Harry, the Duke of Edinburgh, Prince Charles, and Camilla, Duchess of Cornwall were also in attendance.

Kate, 35, dazzled in a regal, lace, pink gown by Marchesa. Commentators were quick to point out that the low-cut gown was a more risqué choice for the Duchess, who seldom wears plunging necklines. The mom-of-two paired the dress with a sparkling necklace on loan from the Queen.

The pièce de résistance of Kate’s look, though, was the diamond and pearl Cambridge Lover’s Knot tiara. The tiara was a wedding gift to the late Diana from the Queen, and was known to be one of her favorite pieces. The Duchess is clearly very fond of the tiara as she wore it at last year’s state banquet, too.

This is not the first time Kate has channeled Princess Diana. She has been known to model her style on the late princess on numerous occasions. What is more, it certainly isn’t difficult to draw parallels between the nation’s affection for Kate and the national love for the people’s princess, Diana.

The prestigious state banquet earlier this week was part of King Felipe VI and Queen Letizia’s three-day visit to the UK, and marks 31 years since Felipe’s father, Juan Carlos, last visited. Over one thousand people from 130 countries around the world attended the banquet to celebrate the bonding of nations with the hope that relations over Brexit and Gibraltar will improve.
