Camilla was also donning her favourite fitness gadget: a Fitbit.
The tool allows you to keep in shape by tracking the movement.
While visiting Egypt and Jordan last month, the 74-year-old Duchess was also spotted wearing the gadget.
The tool seems to be her favourite accessory to help her stay fit and in good shape.
For today’s event, Camilla opted for natural makeup with a dash of mascara and styled her hair in her signature platinum blow-dry.
Many royal fans took to social media to comment on the Duchess’s fashion choice.
Instagram user Malvika Mathur said: “Duchess looks perfect.”
Aigerim Sadir commented: “Beautiful lovely Camilla!”
The Duchess of Cornwall joked she became “quite ratty” if disturbed while listening to the soap.
The Archers is a BBC radio drama broadcasted for the first time in 1951.
The show, which shared the “everyday story of country folk” is the world’s longest-running drama.
