When it comes to curating a refined wardrobe, few can rival the Princess of Wales. While she’s famous for her tailored coats, polka dot dress and pointed pumps, she’s also a dab hand at adding a pair of refined trousers into her roster of elegant basics. Case in point, the effortlessly chic Sézane trousers she sported on a recent visit to British eyewear brand Finlay in Notting Hill.

Middleton, who has previously endorsed the French label on multiple occasions (we love her cream knitted set), wore the high-waisted Martin Trousers in grey with a black wool coat for her outing in the capital. This isn’t the first time she’s worn the wool trousers, previously pairing it with a white button-down and knitted vest for an elevated preppy look back in October 2023. All of which to say, they’re timeless and sophisticated no matter how they’re styled.

While Middleton’s exact grey pair is sold out in most sizes (we highly recommend signing up to snag a pair once it’s inevitably restocked), Sézane’s Martin Trousers are available in an array of shades. You’ll find the navy iteration is just as versatile while the checkered, gingham and corduroy pairs make for great statement additions to your trouser rotation.

A bonafide classic, the French label’s reputation for crafting long-lasting basics ensures you’ll be wearing these Kate Middleton-approved trousers for years to come.
