Senior royals and esteemed guests donned their white tie finery – and their tiaras – for a night celebrating the diplomatic ties between the two countries. The state banquet, a highlight of any state visit, is particularly significant to solidify ties between the US and UK. The dress code for a state banquet is typically white tie, court dress and full dress uniforms. The caption read, ‘The King and Queen inspect the banquet table in St George’s Hall ahead of this evening’s State Banquet. The culmination of work across the Royal Household, every detail needs to be perfect for a visiting Head of State.’
