It's been more than two decades since the Princess of Wales stepped into the royal spotlight, and yet her sartorial prowess has never been more admired.
From gracing the stage as St Andrews University It-girl to eventually becoming Prince William's beautiful royal bride, the nation quickly developed an obsession with the way the Princess dressed - a phenomenon we now refer to as 'The Kate Effect'.
"Women around the world wanted to be Kate Middleton, and in the early days when Kate mostly favoured high street brands, her fans were able to emulate her, even if it was just a token nod," explains royal style expert, Miranda Holder.
"Kate manages to tread that awkward line between fashion and the restrictive etiquette limitations of the working royal perfectly - and all this makes utterly compelling viewing, keeping us hooked."

In 2023, the mother-of-three surprised the nation when she attended the BAFTAs wearing the same dress she had worn to the event four years earlier. In November, she sparked joy in a bow-adorned hat on Remembrance Sunday that had first been worn to Prince William's graduation from Sandhurst in 2006 before they were married.
From rocking reworked Alexander McQueen to upcycling former flattering fits, Kate's stance on sustainable fashion continues to position her as an icon of environmental dressing.
Here, see her best outfit repeats of the last twenty years.

The royal opted for an ethereal one-shoulder piece, a white layered gown that flowed elegantly as she walked alongside her husband at the BAFTAs in 2023.
The design was cinched in at the waist with a waistband that flattered her silhouette and featured a cascade of drapery over her left shoulder. Showing off her commendable eco credentials, Kate's choice of gown was actually a repeat wear that she wore previously to the prestigious awards ceremony in 2019.
