Kate appeared in a long navy coat paired with some black wide-leg trousers and a black polo neck to complete the chic look.

A spokesperson for Dalston-Mill Fabrics commented on the findings for Express.co.uk.

They said: “After her short break of public appearances over Christmas, this data shows the Duchess’ enduring ability to inspire style choices up and down the nation with a single appearance.

“Wearing a recycled navy coat styled with some smart trousers and navy heels, Kate showed off her impeccable fashion choices whilst still being cost-effective.
