When it comes to fashion, it's undeniable that Duchess Catherine and Duchess Meghan are dab hands - in every sense of the phrase.
Indeed, the sisters-in-law have proved their impeccable fashion sense time and time again, whether it's a casual chic ensemble for a daytime public appearance, to lavish accessories and full glamour for black-tie soirees.
And as with many style icons, we can't help but copycat their style - but in a surprising turn of events, the same apparently goes for royals.
Even before they were officially made Duchesses, the two royals were known to wear very similar styles from time to time.
And who could blame them? If we're taking fashion cues from the daring Duchesses, then there's no reason why they can't themselves.
But it might not have been a simple coincidence. Before Meghan married Harry in May 2018, Middleton was reported to have given the bride-to-be some handy fashion advice as she prepared to enter the royal fold.
According to The Independent, the Duchess of Cambridge advised Markle on royal wardrobe protocol and how she will have to adapt to it in the future.
"She has provided Meghan with names of some of the favourite UK go-to designers on everything from dresses, coats and the all-important British hat," a source told the publication.
Since then, Meghan has worn some of Kate's favourite designers including Emilia Wickstead and Self Portrait, so it looks like the advice was well and truly taken on board!
To celebrate, admire and simply feast our eyes on the Duchesses winning (and twinning!) style, we've rounded up their very best matchy-matchy moments. Keep scrolling for all the fashion inspiration you'll ever need.
