The Duchess of Cornwall was among the royals present at the Remembrance Sunday service in Whitehall, London on 8 November.
Camilla, 73, was dressed appropriately for the moving event and wore a black coat with an elegant lace trim, layered over the top of what appears to be a lace dress.
Pinned to her left lapel was her new Rifles brooch and a poppy as a mark of respect to honour fallen soldiers from the First World War and other conflicts.

The service was closed to the public for the first time in history this year due to the coronavirus pandemic, and the public had been asked in advance not to gather at the Cenotaph.

Around 10,000 people usually gather at the Cenotaph annually for the National Service of Remembrance to witness the two-minute silence at 11am.
Earlier this week, the Duchess wore a familiar outfit for her visit to the Field of Remembrance at Westminster Abbey in London.

Camilla sported a deep green midi coat featuring black fluffy cuffs and a matching collar – a sentimental piece which she has owned for over thirteen years and one she has worn to meet soldiers on several occasions previously.
Pinned to her coat were two brooches including a poppy design known as the 'Returning Home Brooch' and her Rifles brooch.
Clarence House released a stunning new portrait of the Duchess to mark her official appointment as Colonel-in-Chief of The Rifles regiment. Camilla took over the role from her father-in-law, the Duke of Edinburgh, in separate handover ceremonies at Windsor Castle and Highgrove House in July.
