The Duchess of Cambridge debuted her fall wardrobe with a pair of $108 khaki culottes by Jigsaw on Wednesday.
Kate Middleton dressed for the London weather with a burgundy turtleneck sweater, matching heels, and a $3,600 Chanel handbag as she headed to an engagement at the Natural History Museum.
The style of trousers has become a go-to for the duchess in recent months. She wore a similar black pair by Zara for a visit to a children's hospital in September.
However, the royal is still likely to be spotted wearing designer dresses to the majority of royal engagements.
She completed the look with her burgundy heels, her signature blow-out, and minimal makeup.
Middleton was there to visit the museum's Angela Marmont Centre for UK Biodiversity to hear about its work protecting UK wildlife.
It's the royal's last engagement in the UK before she embarks on an official tour of Pakistan with Prince William next week.
The official visit is set to be "the most complex tour" undertaken by William and Middleton, according to a statement by the couple's communication secretary.
"As with previous overseas visits, The Duke and Duchess have asked that this tour allow them opportunities to meet as many Pakistanis as possible," the statement reads.
"Over the course of the visit, Their Royal Highnesses will meet a wide variety of people, including children and young people, leaders from government, business and the charity sector, inspiring conservationists, and well-known cultural figures and sporting stars.
"This is the most complex tour undertaken by The Duke and Duchess to date, given the logistical and security considerations. Pakistan hosts one of Britain's largest overseas networks, with the British High Commission in Islamabad being one of the UK's largest diplomatic missions in the world."
