Royals wearing fancy dress: All the times Kate Middleton, Queen Maxima and more have worn costumes

Just because they're royal doesn’t mean they can’t have fun dressing up! While people around the world often opt for royal-inspired costumes, these real life royals show us how they play dress up. From Kate Middleton to Princess Grace’s granddaughters, take a look at various royal family members rocking fun costumes…

The Duchess of Cambridge, pictured with Prince George and Princess Charlotte at a polo match, was spotted going grocery shopping in Sainsbury's, Norfolk during the autumn half term in October 2019. A customer said Kate was browsing the Halloween costumes with George and Charlotte and asked another shopper's children what they were going to dress up for the annual holiday. 

Princess Madeleine of Sweden shared this adorable family snap of her three children during Halloween 2018. The royal mum was dressed as a cat, complete with ears and painted on whiskers, while daughter Princess Leonore looked cute in a pastel mermaid outfit and son Prince Nicolas donned a Batman costume. Princess Adrienne made the perfect Halloween pumpkin, as her mum held her in her arms for the Instagram photo. 

Princess Beatrice was spotted at Annabel's Halloween party in October 2018, wearing a monochrome look with a bright lilac wig and a unicorn headpiece - very on trend! The royal finished off her costume with a touch of a sparkle on her accessories. 

Princess Grace's granddaughter Pauline Ducruet looked spooktacular for a Halloween party in 2013. The young Monaco royal showed off her elaborate makeup on Instagram, which she simply captioned: "#halloweenparty #nimportenawak #bonsoooiir !! .." Photo: Instagram/paulinedcrt

Princess Leonore of Sweden looked cute as a bug for Halloween 2015.

Princess Stephanie of Monaco’s youngest child, Camille Gottlieb, drew inspiration from the horror film Saw for her 2016 Halloween costume. Grace Kelly’s granddaughter shared a picture of her creepy Jigsaw-inspired get-up writing, “Let play a game  #Saw #Halloween2016#ThereIsJustOnRule." Photo: Instagram/camillerosegottlieb

It seems Camille may have been inspired by her older sister Pauline who, a few years prior, donned her own version of the Saw killer ensemble. "Happy halloween ! #saw #letsplaythegame #london ," she penned alongside her photo in 2014. Photo: Instagram/paulinedcrt
