But there is one fashion moment that royal fans love above all others – when the Princess gets the chance to wear a tiara.
And the countdown is now officially on following the news that William and Kate are set to take on a major role at this week’s state visit by the President of South Africa.
On Tuesday, the couple will greet President Ramaphosa on behalf of King Charles III at the Corinthia Hotel before travelling with him to Horse Guards Parade where the President will receive a ceremonial welcome and meet with the King and Queen Consort Camilla.
The royals and the president will then join a carriage procession along The Mall before King Charles hosts a private lunch at Buckingham Palace.
That evening, the royal family will don their finery for a State Banquet at the Palace. Prince William and Kate will both be in attendance – and all eyes will be on the Princess as she showcases a gown and glittering tiara.
It will be a rare and special moment. Princess Kate has only worn three tiaras on 11 occasions.
We first saw Princess Kate sport a tiara at her wedding in 2011. For the highly anticipated occasion watched by millions, she wore the Cartier Halo design, which perfectly complemented her Alexander McQueen wedding dress. Traditionally, tiaras are a symbol of marriage and are often donned by brides on their special day.
Tiaras are also allowed to be worn for official state banquets – which is why Prince Kate wore one for the annual Buckingham Palace diplomatic reception in 2013.
