The Duke and Duchess of Cambridge today joined dozens of royals from around the globe for a special lunch celebrating the Queen's Diamond Jubilee.
Wearing a £1,200 pink Emilia Wickstead dress with pleated skirt, Kate looked entirely at ease as she mingled with the international royals, chatting warmly with Princess Charlene of Monaco and sharing a joke with the King of Jordan and his wife.
A sneak peek at the seating plan showed there were 24 Kings and Queens, one Emperor, a Grand Duke and a Sultan.
Eight princesses, an Emir and a lone Empress added a further layer of gravitas to the mix.
Pretty in pink: Kate wore a simple pleated dress as she joined William for the Queen's celebratory lunch at Windsor Castle today
Today's World Sovereign’s lunch at Windsor Castle to celebrate the Queen’s Diamond Jubilee was almost certainly the largest gathering of crowned heads of state since our own Queen’s coronation in 1953.
But the joyousness of the occasion was overshadowed by a growing row about some of the more controversial names on her guest list and sparked demonstrations outside Buckingham Palace, where a second lavish black tie dinner was being thrown later in day by Prince Charles for some of the lunch guests.
Indeed the Queen, who has spent the last 60 years managing to sidestep such political controversy, has found herself accused of making a catastrophic error of judgment today by dining with the King of Bahrain, whose regime is accused of a catalogue of human rights abuses.
