Kate Middleton in a navy jacket and trousers

Kate Middleton’s maternity leave is officially over as she’s now getting back to her official royal duties, albeit with her husband Prince William at her side.

We need not remind you that the couple welcomed their second child Princess Charlotte, a baby sister for two-year-old Prince George, back in April, and while they’ve been out in public for her Christening, yesterday marked the first official engagement Kate has carried out since giving birth just a few months ago. Those royals don’t hang about, do they?

And while they left their adorable kiddies at home (sob!), we were still happy to see the smiling duo in attendance at America's Cup World Series, an international yacht sailing competition, in Portsmouth on Sunday.

Giving those Alexander McQueen coat dresses a well earned break, Kate’s attire was more casual than her usual garb.

Kate’s latest look consisted of a slim taper trouser in navy, beige boat shoes and thermal fleece given to her by the sailing club.

Yep, it may have looked like a pretty safe ensemble from the front but, when the 33-year-old turned around, we realised her outfit was way more fun than we initially gave her credit for.

Emblazoned on the jack of her regatta fleece was her official title, ‘The Duchess of Cambridge’, taking the monogramming trend to a whole new, very royal level. However, she wasn’t the only one to be honoured with a personalised zip-up…

You guessed it — Prince William also flaunted his bespoke jacket decorated with his title, ‘The Duke of Cambridge’, for all to see. Then the glorious moment came when they stood side-by-side together…

This is TOO good.

So, next time your other half rolls his eyes when you try to coordinate your looks, you may just want to show him this. If Prince William can stomach matchy-matchy outfits then so can he, goddamnit.
