Kate Middleton at 40: How the Duchess of Cambridge's style evolved from youthful sparkle to timeless elegance

Written by Leah Dolan, CNN

Since joining the royal family in 2011, Catherine, Duchess of Cambridge — known by many as Kate — has rarely faltered on her unwritten obligation to appear manicured and immaculately dressed in the public eye. And while the duchess is renowned for her preppy tweeds and tailored blazers, she earned her true fashion credentials through a sharp eye for occasion wear.

Take, for example, the gilded Jenny Packham dress she wore for the 2021 premiere of “No Time to Die” that set the internet alight, or her custom Alexander McQueen wedding dress with detailing so precise that seamstresses had to replace their sewing needles every three hours, according to British Vogue.

But even before she became a duchess, a young Kate Middleton kept her wardrobe well stocked with statement looks. For the queen-consort-in-waiting’s 40th birthday, we look back at some of her best outfits, from her heady college days to the most formal of royal occasions.

The college years

While a pre-royal Kate was studying at St Andrew’s University in Scotland, her social life seemed similar to that of many people her age. Bunched in the back of taxi cabs, she may have worn shorter hemlines than she does now, but Kate’s love for dressing up was evident from the start.

Paparazzi photos snapped of Kate as a bright-eyed 20-something suggest a penchant for sparkle: glittering black mini dresses and emerald green sequin halter-neck tops were go-to looks. Even before she became the one of the world’s most photographed women, her sartorial sensibility skewed bold — for instance, if friends wore all-black ensembles for a night on the town, Kate donned a baroque-printed silk dress.
