The Princess of Wales could be set to shimmer in December

Kate Middleton might be preparing for another tiara moment — and it could happen soon.

The Princess of Wales, 43, has had two tiara moments so far this year, and Buckingham Palace previously hinted at when the next occasion requiring the royal accessory might be.

In October, the palace announced that President Frank-Walter Steinmeier of Germany accepted King Charles’ invitation for a state visit to the U.K., in a trip that will run from Wednesday, Dec. 3 to Friday, Dec. 5.

State visits are an important way for the British royals to maintain relationships with representatives of foreign nations, and the first day of the official trips is typically capped with a state banquet, where tiaras are traditional attire for the royal women.

As the Prince and Princess of Wales, Prince William and Princess Kate almost always attend these diplomatic dinners (and help host the trips).

Though the British royal family is famous for its tiara collection, women in the family don’t actually wear them very often. They typically only don the headtoppers for weddings or events of the utmost formality.

Princess Kate slipped on Queen Mary’s Lover’s Knot Tiara, the most frequently worn tiara in her rotation, for her two tiara wears earlier this year. The Princess of Wales shimmered in the historic headpiece for the French state banquet at Windsor Castle in July and wore it again for the September state banquet at the castle commemorating U.S. President Donald Trump’s state visit to the U.K.
