Kate Middleton and Camilla Parker Bowles attended separate events this week wearing the same special jewelry.

Hello! shared photos of the Duchess of Cambridge and Duchess of Cornwall wearing a very special edition of the poppy pin, which is a tribute to women who served in the First World War. Middleton wore it when she visited the Imperial War Museum. On the other hand, Camilla used it during her whirlwind royal tour with Prince Charles in the Gambia.

"The Duchess of Cornwall is wearing a special poppy to thank the women who served and supported the war movement during the First World War. In this important centenary year, 100 years since the end of WWI, The @PoppyLegion are leading the nation in a #ThankYou100 #Armistice100," Clarence House wrote on Twitter.

The publication noted that the brooch is sold for $38.93. It was exclusively designed for the Centenary anniversary. It comes with a certificate commemorating the life of a woman who lost her life as a direct result of the First World War.

The poppy pin comes with a gold tone and a hand finished with baguette crystals which makes it a great sparkling accessory to the royals' winter coat.

While Camilla and Middleton opt for the same badge, Meghan Markle hasn't been seen wearing it. However, the Duchess of Sussex wore another poppy pin for during her tour to Australia, New Zealand, Fiji and Tonga with Prince Harry.

According to Bustle, Markle used the "Remembrance Poppy," which is worn to honor the fallen troops of war. It is taken out during the two weeks before Remembrance Sunday, which is on Nov. 11. These are most common in the United Kingdom, Canada, Australia and New Zealand, a tradition that started back in 1921.

Poppins is worn on the left chest to symbolize that those who died were kept close to one's heart. According to BBC, it is placed where military medals are worn. Others say that men should wear it on the left and women on the right. However, Queen Elizabeth II, herself, wears hers on the left.

In related news, aside from wearing similar poppy pins, Camilla has reportedly taken cues from Middleton in recycling outfits. In fact, the Duchess of Cornwall's entire wardrobe during the second day of Royal Ascot was similar to what she wore at the Prince of Wales' Garden Party in May.
