Duchess Catherine's latest appearance reveals a big clue about her evolving wardrobe

This week, Duchess Catherine made her fans sit up and take notice as she released a new video of herself captured by herself on a camera phone.

Indeed, stills of the British royal at her Norfolk country estate in her workout gear were splashed across Instagam and Facebook as fans poured over the rare sighting of the Duchess in such a casual context.

In the video, Kate spoke about the importance of mental health among children and their parents, particularly amid such difficult times.

"There has never been a more important time to talk about parental wellbeing and mental health too," she said in the poignant video.

Her words resonated enough in their own right, but her outfit was also a talking point among fans.

Indeed, the Duchess' chic ensemble was perfect for a winter workout. Wearing a navy coloured Barbour jacket and a matching woollen hat with a bobble, we wouldn't blame you if you're inclined to recreate the outfit yourself.

But what's more, the outfit gave away a key piece of information about Kate's current wardrobe set-up.

Indeed, the cute woollen hat she wears is nearly identical to that of her former stylist, Natasha Archer.

As pointed out by HELLO!, a near replica of Kate's pom-pom beanie was also spotted on her husband and renowned royal photographer Chris Jackson's Instagram just weeks ago.

In the Instagram story, their baby son Theo is seen wearing the hat, with Chris explaining: "Stolen mummy's hat."

Of course, this could well be a coincidence, - both women are incredibly fashionable in their own right.

It is understood Natasha stopped working with Kate as her stylist after she welcomed her baby in 2018, though it's unclear as to whether she has now returned to her former styling role.

Certainly, this lookalike moment may suggest Natasha is back in action in the land of Kate's heavenly wardrobe - and to be frank, we're not mad about it at all.

But whether the talented Natasha had a hand in it or not, there's no denying we're keen as pie to recreate the Duchess' outfit ourselves.

As the summer months come to an end, we'll no doubt be in the market for some winter appropriate activewear.

To save you the run-around, we've sourced some dreamy outfits to get you through in true Kate-style.

Now you'll have no excuse not to go on that run - rain or shine.
