Heiress Marie-Chantal of Greece in cornflower-blue at Charles III's coronation: gorgeous!

The royal princess Marie-Chantal also has her own children's brand, which released a special collection in honor of the Coronation. Last month she attended the Prince's Trust Global Gala at the exquisite Cipriani South Street alongside Kate Moss, Sienna Miller, Rita Ora and Charlotte Tilbury.

The children of the Greek family who did not attend the Coronation were Princess Maria-Olympia, 26, Prince Constantine-Alexios "Tino", 24, Prince Achilleas-Andreas "Archie", 22, Prince Odysseas-Kimon, 18, and Prince Aristidis-Stavros, 14.

Royal Prince Pavlos and Royal Princess Marie-Chantal currently reside in New York, where they live with their three youngest children, although their London home is on Cheyne Walk. When they are in England, they also stay at their home in the Cotswolds, where they hosted Valentino and Queen Maxima of the Netherlands, Paris Hilton and India Hicks, who came for Pavlos and Olympia's joint birthday party in 2017.

The couple visited London's Oswald's Private Club on Friday night with other members of the royal family, including Princess Anne, Princess Beatrice, King Carl XVI Gustaf of Sweden and his daughter, Royal Princess Victoria, Zara and Mike Tindall, Prince Albert II and Princess Charlene of Monaco, Lady Sarah Chatto, the Duke and Duchess of Edinburgh and their children, Lady Louise Windsor and the Earl of Wessex.
