We can only imagine what the inside of Duchess Catherine's glorious wardrobe at Kensington Palace looks like, but we have no doubt it's filled with rack upon rack of gorgeous designer threads.
And because some of Kate's clothes are just too beautiful to wear once, the Duchess is all about recycling her favourite looks, time and time again, year after year.
This week we've seen Kate's sister-in-law Duchess Meghan recycle some of her favourite outfits during the #SussexRoyalTour of Africa, but Kate just stepped out in a pretty blue coat that she's worn not once, but three times before.
Kate has previously worn the light blue coat dress by Alexander McQueen twice in 2014, once to a WW1 commemorative and Flying Day and again a few months later to commemorate the 70th anniversary of the D-Day landings, as well as once in 2016 at the 75th anniversary of the RAF Air Cadets.
Today, she paired the look with an Asprey clutch, navy heels and diamond earrings and her signature bouncy blowout.
Kate and her husband Prince William attended the naming ceremony of the UK's new polar research ship, the RRS Sir David Attenborough, along with the man himself, in Birkenhead, England.
Initially, the British public were invited to choose the name of the boat and the hilarious winning name was Boaty McBoatface. However, that vote was vetoed, so the ship is instead named after the celebrated climate activist.
Both William and Sir David gave speeches at the event, before Kate had the honour of formally naming the ship and smashing a bottle of Champagne, by pressing a giant yellow button from afar, to celebrate the occasion.
Kate is a huge fan of recycling her outfits. It doesn't matter if it's a coat, a casual dress or a ballgown - she's more than happy to rewear her favourite looks.
Last November, she stepped out wearing a turquoise gown from one of her most-loved designers, Jenny Packham, which she had worn six years beforehand.

And just a few months ago in June, the Duchess stepped out at a gala dinner for the UK's Addiction Awareness Week wearing a white off-the-shoulder Barbara Casasola design, an ensemble she first dazzled fans with back in 2016.
Kate looked almost identical in the same attire, when she presented the Art Fund Museum of the Year Award at the Natural History Museum.
