Princess Anne was the picture of elegance as she joined her royal family at the Royal British Legion Festival of Remembrance at London's Royal Albert Hall on Saturday night.
The Princess Royal, 74, cut a sophisticated figure in a sculpted black dress layered with a tailored suit jacket elevated with satin lapels.
The royal slipped into patent black loafers and tights for the occasion, adding a printed black and white scarf to add dimension to her monochrome ensemble.
Princess Anne paired her oversized poppy brooch with a striking silver brooch adorned with a large oval pearl - a brooch believed to have been worn by Queen Elizabeth, the Queen Mother, during the christening of Prince Michael of Kent in 1942.
As identified by Spanish Royal Jewels on Instagram, the Princess Royal first wore the ornate pin during the annual dinner of the Royal Academy of Engineers in July 2023.
It marked the first time the royal had worn the rarely seen pearl brooch. Pearls are thought to be a more discrete, less striking jewel than diamonds and more respectful to wear during periods of grief.
November is one of the only times of the year outside of official periods of mourning where the royal family will exclusively wear black; a sign of respect for the fallen in the Armed Forces.
Traditionally, the royals also wear a poppy brooch to show support for the service and sacrifice of the Armed Forces, veterans and their families.
