Kate Middleton Wears Diana's Favorite Tiara at State Banquet
Confirmed
In Short: Princess Kate Middleton wore Queen Mary's Lover's Knot tiara, a favorite of Princess Diana, for a state banquet at Windsor Castle.

At the state banquet hosted by King Charles and Queen Camilla for Sultan Haitham bin Tarik of Oman, Kate Middleton chose to wear the Lover's Knot tiara, a piece that has become her go-to for royal events.
The tiara, which features 19 arches and 28 drop-shaped pearls, was first commissioned by Queen Mary in 1913 as a copy of a tiara owned by her grandmother, Princess Augusta of Hesse-Kassel.
Kate has worn the tiara multiple times since 2015, and it is considered her favorite among the five tiaras she has used since marrying Prince William in 2011.
The tiara was loaned to Diana by Queen Mary in 1981, and it is one of only two tiaras Diana was photographed wearing.
Royal commentator Amanda Matta noted that Kate's choice to wear the tiara is a romantic gesture that ties into the sentimentality of William and Kate's royal love story.
Kate paired the tiara with a flowing, sunshine-yellow gown by Elie Saab, King Charles' Royal Family Order badge, and the Royal Victorian Order sash and star.
Former royal butler Grant Harrold believes Kate wears the tiara to keep Diana's memory alive and to ensure people continue to remember her.
Christopher Andersen, author of 'Kate!', told Fox News Digital that Kate's modern approach, family values, and 'soft power' make her a vital asset to the royal family and the UK.
Kate's choice of the tiara also reflects her conscious effort to incorporate elements of Diana during her time as Princess of Wales, according to royal experts.
The tiara's sentimental value and its status as a favorite of both Diana and Kate make it a significant piece in royal history.
Kate's fashion choices at state events are crucial to her role as a future queen, and she takes a slow and steady approach to evolving her style.
The tiara's history and its connection to both Queen Mary and Princess Diana add to its significance, making it a fitting choice for Kate's latest royal appearance.
