Best royal Christmas Day fashion moments

In 2019 Kate matched her outfit with Princess Charlotte's (cute!), accessorising her grey Catherine Walker coat with pine green details, including a fascinator, pumps and a clutch bag.

I will always be obsessed with Diana's hot pink Christmas Day ensemble. The ruffle collar! The intricate buttons! And don't even get me started on that hat. Utter. Perfection.

Meghan Markle knocked it out of the park for her first Christmas with the royal family. Photographed alongside (then fiancé) Prince Harry, Meghan wore warm spice and neutral tones, starting with her camel Sentaler coat, offset by a caramel Philip Treacy hat, top-handle Chloé bag and Stuart Weitzman boots.

Conversely, for Kate's first Sandringham Christmas, the new royal sported a plum-toned getup including a collarless coat dress and hat-turned-fascinator by Jane Corbett.

Whoa! Only Princess Diana could wear a bright purple and printed coat dress for Christmas Day with the royals and pull it off so effortlessly. This is everything.

For the 2018 service, Kate looked radiant in this berry red coat dress with a Mulberry Bayswater clutch and Gianvito Rossi heels.

Meghan and Harry wore matching navy looks in 2018, with the Duchess sporting a sleek Victoria Beckham coat with a feather fascinator and leather boots. Love!

Mixing things up a bit with a pastel-look, Diana wore a buttery yellow and black grid check print coat for Christmas 1987. Note how she matches her belt, boots and clutch all to the coat like a seasoned fashion pro.

Remember when Kate stepped out wearing this plaid Miu Miu coat dress? The whole thing was made even more amazing by the furry black hat, giving the look an extra wintery feel.

It is outfits like this that earnt Diana her '80s style icon status. The power-suit tailoring, bold colours and OTT accents make this skirt suit one for the ages.

Pregnant with Princess Charlotte at the time, Kate stepped out wearing a brown tweed coat by Moloh and a Lock & Co chocolate pillbox hat for Christmas 2014.

Throwback to 1981, when Diana wore this puff-sleeve emerald green look - with intricate detailing around the collar and pockets, and a hat in the exact same hue.

In 2016, Kate ditched the fascinator and hat altogether, opting for a more relaxed blow-out to complement her burgundy coloured Hobbs coat and matching scarf.

A famous Alexander McQueen fan, Kate sported a pleated tartan coat dress by the designer, paired with a matching Gina Foster fascinator and calf-high boots for the 2013 service.

In 1993, Diana wore this (now iconic) holly red overcoat, contrasted perfectly against her statement black hat. The look is so timeless, Kate famously recreated it years later.

Alternating between red and green festive looks, Kate sported this forest green Sportmax number in 2015, finished with knee-high Aquatalia boots.
