The 72-year-old wore a black cape over a monochrome dress with a ruched, asymmetrical hem and a pair of black suede boots.
Camilla's choice of a cape jacket shows that it isn't just the younger royals, like Kate, who keep up with the latest catwalk trends.
Capes are set to be huge, and they were featured all over the 2019 Autumn/Winter catwalks during London, Paris, New York and Milan Fashion Weeks.
While Camilla is usually seen in more traditional fashion choices, Duchess Kate often pushes boundaries with her choice of outfits.
During her recent trip to Pakistan with her husband, Prince William, Kate wore a multitude of looks suited to the local culture and her surroundings.
While playing a game of cricket in Lahore, the 37-year-old wore a traditional shalwar kameez - a tunic-and-trousers combination worn by both men and women throughout the region.
During the tour the duchess wore a number of beautiful outfits, including a gorgeous green sequin gown that nodded to the Pakistani flag.
From stunning white looks, to traditional bold colours, Kate's Pakistan tour wardrobe was incredible.
Kate broke her own rules recently, posting a personal message to the Kensington Royal Instagram account.
The Duchess of Cambridge penned a note to inform followers about the work of a charity she visited with Prince William on their royal tour of Pakistan.
"The community at the SOS Village is built around family — and the best possible family you could imagine — where everyone comes together to nurture, love and protect the children in their care," the mother-of-three wrote in her first Instagram message.
"These vulnerable children, many who have come through traumatic circumstances, are nurtured in this caring environment and are able to form these quality relationships that they so desperately need to thrive," Kate continued, before signing off as "Catherine."
