Though not an exact replica, the look was widely seen as a nod to her wedding outfit from 2005, both in tone and in the refined simplicity that defined it.

Camilla and Charles were married on April 9, 2005, in a civil ceremony at Windsor Guildhall, followed by a religious blessing at St. George’s Chapel, Windsor Castle, led by Archbishop Rowan Williams.

Both were divorced at the time — Charles from Princess Diana, and Camilla from Andrew Parker Bowles — which influenced their decision to hold a civil ceremony. Originally set for April 8, the wedding was postponed by one day to allow Charles to attend Pope John Paul II’s funeral.

The ceremony was attended by close family and friends, including Princes William and Harry, while Queen Elizabeth II and Prince Philip did not attend the civil service but joined the chapel blessing and hosted a reception afterward at Windsor Castle.

Following the marriage, Camilla became Her Royal Highness The Duchess of Cornwall, choosing not to adopt the title Princess of Wales.

Nearly twenty years later, her elegant tribute in Rome reminded many of how far she and the King have come — and how she continues to balance modern sophistication with quiet nods to royal history.
