Kate Middleton joined members of her family and the House of Windsor for a special V-E Day commemoration on Monday in London. The British royal family marked the 80th anniversary of Victory in Europe Day, which marks the formal end of World War II.

For the special, historic occasion, the Princess of Wales rewore a dress from her royal wardrobe, a mostly monochrome attire. The bespoke coatdress was created by British designer Emilia Wickstead in an aubergine hue.

Around 1300 members of the armed forces, including the Royal Navy, the Royal Marines, the British Army and the Royal Air Force, along with Commonwealth nations, Ukraine, and Nato allies are taking part in the military procession for Victory in Europe Day, which is celebrated each year on May 8, marking the day the Allies formally accepted Germany's surrender in 1945.

The dress featured long sleeves and a flowing skirt with subtle pleating. A cinched waist added definition to the ensemble. The dress also took inspiration from suited attire with sinuous lapels with sharp angles. Kate coordinated the dress with her pillbox hat courtesy of Sean Barrett Millinery.

To complete the ensemble, the Princess of Wales wore a pair of neutral pumps by Ralph Lauren. The American designer is one the British royal gravitated toward during her recent excursion to Scotland alongside husband Prince William at the end of April.

To accessorize her look, Kate opted for pieces of jewelry with certain significance for the occasion, as well as pieces that coordinated with her ensemble. The Princess of Wales wore a Royal Navy Air Fleet Pin, a way to honor the veterans who attended the special ceremony.

She also wore a ruby necklace, which coordinated seamlessly with her ruby and diamond earrings. As for the rest of the Wales family, Prince William donned military garb for his attire. The Prince and Princess of Wales’s children wore mostly muted tones in navy, with 10-year-old Princess Charlotte wearing the same ensemble she styled for 2024 Christmas Day celebrations.
