11 Royal Costume Ideas to Wear This Halloween (2024)

Her Majesty isn't only the Queen of the U.K.—she's also queen of iconic royal style. Her matching coat and hat combos in bold, eye-catching colors have become the monarch's signature look, which also makes them perfect for an instantly recognizable Halloween ensemble.

Elizabeth isn't one to shy away from a daring hat, and neither should you—all you need is a dress or coat to match, and you can consider your look complete.

Long before she was the duch*ess of Cambridge, Meghan Markle made a name for herself opening those famous silver briefcases on the hit game show Deal or No Deal. Consider this costume a litmus test for your royal-loving friends—true Meghan fans will understand.

Throw on your favorite co*cktail dress, get your hair in bombshell shape, and don't forget your most essential accessory. Bonus: this baby will hold way more Halloween treats than your standard clutch.

Not everyone's grandmother can lend them a 93.7 carat emerald tiara, but with a long white dress and the right piece of costume jewelry, you can certainly still pull off this majestic wedding look.

Whether you're looking to costume the whole family as Cambridges or just want to pay homage to this dapper young royal, this example of George's go-to outfit of collared shirt, shorts, and high socks will look positively precious on would-be royals of all ages.

Kate may be a duch*ess, but when it comes to sporting stylish coatdresses, she reigns supreme. Lately, she's also taken to styling her all-in-one frocks with a twist on the traditional chapeau, opting instead for an elegant, modern hatband.

For maximum duch*ess style, choose a luxe hair accessory with some heft and wear it angled forward on the head to make everyone at the party look twice to decide whether you're wearing a headband or a hat.

There are dozens upon dozens of iconic Diana fashion moments to choose from, but if you're looking for pure bang for your buck this Halloween, it doesn't get much better (or comfier) than her famous Harvard sweater and biker shorts workout look.

Odds are you have most everything you need to pull off this costume already in your gym bog, but to really boost the recognizability, a white Harvard sweatshirt is a must.

It's no secret that Queen Elizabeth is a dedicated dog lover and her numerous corgis clearly hold a special place in the monarch's heart. So what better way to pull off an under-the-radar royal costume (or, dare we suggest, an out-of-the-box couples costume paired with the Queen?) than by dressing as one of her favorite pooches?

This cozy corgi onesie earns points for ease, comfort, and pure adorability.

Members of the royal family all have exceptional wedding hat style, but when it comes to over-the-top toppers, nobody does it quite like Princess Beatrice.

From herfamous/infamous hat at Will and Kate's wedding, to the butterfly-covered number she sported to Autumn Philips's nuptials, this is one costume that definitely won't get lost in the crowd.

Kate Middleton has been making style waves ever since she came into the public eye after she and William started dating, but the fashion frenzy really took off after the couple announced their engagement in 2010 with Kate wearing a gorgeous blue dress that perfectly complemented her 12 carat sapphire engagement ring.

It may not have come from Princess Diana's jewelry collection like Kate's did, but paired with a navy wrap dress this ring will definitely bring some royal flash to the occasion.

Princess Anne's always been a snappy dresser, but it's her accessories game that's truly statement-making. The Princess Royal fearlessly pairs edgy, athletic sunnies with many of her elegant royal looks for a modern mix that we could all take tips from.

Anne likes her sunglasses sporty, which makes them not only perfect for pairing with your chicest suit for an instantly recognizable look, but also makes them handy for the other 364 days of the year when you're not dressing up like a royal.
