Nigerian President Bola Tinubu, aged 73, is currently on a two-day state visit to the United Kingdom. On March 18, he was received by the British royal family in a grand ceremony. Notably, King Charles wore a striking top hat during the welcoming, which has drawn attention due to its unusualness, as monarchs typically do not don such hats when hosting state visits.

During the occasion, Princess Catherine made a notable appearance by wearing a tiara for the first time this year. She represented the royal family alongside King Charles, Queen Camilla, and Prince William. Catherine dazzled in a green evening gown, complemented by the Lover’s Knot tiara, which she has worn 14 times since first debuting it in 2015. This choice of attire highlights the royal family's tradition and pageantry during significant state events.

The royal welcoming not only underscores the diplomatic ties between Nigeria and the UK but also reflects the contemporary image of the monarchy, where traditional elements are melded with personal style. The attention on King Charles's hat choice indicates a shift in public interest towards the sartorial decisions made during royal ceremonies, suggesting an evolving engagement with royal fashion in the context of international diplomacy.
