Despite the chill in the air, Camilla opted for summer colours, wearing a pale pink summer coat.
The coat, which she wore closed at first, was collarless and featured an embroidered trim on the edges.
She pinned a small brooch to one shoulder.
Underneath the coat, Camilla was wearing a dress in the same colour. It also had a black floral design.
Keeping the look tonal, Camilla wore a pair of tan leather low-heeled court shoes.
The mum-of-two held a small grey leather bag in one hand.
Jewellery completed the outfit, and Camilla chose a pair of pearl earrings as well as her impressive engagement ring.
Her hair was blowdried in to her preferred curled style, and she kept her makeup classic, wearing heavy mascara and pink lipstick.
Camilla has been busy in recent weeks, stepping out with the Queen yesterday and attending a garden party at Buckingham Palace earlier this week.
Yesterday, the Duchess of Cornwall wore a black skirt with a large white spotty print.
She added a white blazer, taking style tips from the Queen herself.
Camilla added white court shoes with a black toe and her everyday pearl and diamond earrings.
For the garden party, Camilla wore a more formal choice, with an extravagant hat to complete the look.
Her powder-blue ensemble was glowing, with the Duchess opting for an elegant dress coat with pocket and shoulder detailing.
The pastel-toned coat was pleated from the waist down, held together by two delicate hook-and-eye closures just above the waist, cinching her figure in.
She wore a under garment of the same colour, with neat, white lining around the neck and running down the middle.
The Duchess complemented the summery look with a pair of pristine white gloves.
In-keeping with the whimsical powder-blue and white colour palate, Camilla topped of the look with a stunning white netted hat with feathery detail.
Adding a sense of royal glamour, she accessorised the garden party outfit with a weighty pearl choker and pair of pear earrings.
