The Most Popular Halloween Outfits for 2026

With Halloween falling on a Saturday this year, there is even more reason to go all-out with your costume.

Wednesday Addams and the Gothic Look

The gothic aesthetic continues to be one of the biggest Halloween trends in the UK, making Wednesday Addams an obvious choice for 2026. Think black dresses, white collars, plaited hair and suitably spooky makeup.

Morticia Addams is another great option for adults, while the wider Addams Family theme works brilliantly as a group costume. Dark, glamorous and instantly recognisable, it's a Halloween look that doesn't require an elaborate costume to work.

Stranger Things

Stranger Things remains a fantastic source of Halloween inspiration, particularly for groups. Eleven, Steve Harrington, the Scoops Ahoy crew, Eddie Munson and the Hellfire Club all offer distinctive looks.

The Netflix Shop's official UK costume range includes Hellfire Club T-shirts, Scoops Ahoy uniforms and Steve Harrington-inspired clothing, making it relatively easy to recreate the show's 1980s style.

For a group of friends, a Stranger Things theme is particularly effective because everyone can choose a different character while still fitting into the same overall look.

Wicked's Elphaba and Glinda

The Wicked-inspired Halloween trend is showing no signs of disappearing. Elphaba's dramatic green makeup and witch-inspired styling makes a striking costume, while Glinda offers a glamorous alternative with pink dresses, sparkling accessories and a magical princess aesthetic.

The pair also make a great best-friend or couples' costume.

K-Pop Demon Hunters

K-Pop Demon Hunters has become another major source of costume inspiration, particularly among younger Halloween fans. The combination of K-pop fashion, colourful styling and supernatural characters offers plenty of opportunities for creative outfits.

It is also a good choice for groups, allowing friends to coordinate their costumes while adding their own individual style.

Classic Witches, Vampires and Skeletons

Of course, traditional Halloween costumes aren't going anywhere. Witches, vampires, skeletons, ghosts and black cats remain reliable favourites.

For 2026, however, classic costumes can be given a modern twist. Think glamorous vampire makeup, gothic witch outfits, skeleton face paint and spooky accessories rather than simply buying a traditional one-piece costume.

Toy Story, Superheroes and Children's Favourites

For younger trick-or-treaters, familiar characters remain popular. Toy Story characters, Spider-Man, Hulk, Disney princesses and Pokémon are all easy choices that children can enjoy beyond Halloween too.

Labubu-inspired costumes and cute-creepy character looks are also tapping into the popularity of collectible toys and unusual Halloween styling.

Make Your 2026 Halloween Outfit Stand Out

One of the biggest trends this year is combining a recognisable costume with your own personal touches. Social media, particularly TikTok, is playing an increasingly important role in influencing Halloween makeup and outfit choices in Britain.

Whether you choose Wednesday Addams, Elphaba, a Stranger Things character, a classic vampire or something completely original, the best Halloween outfit is one that lets you have fun. Add dramatic makeup, face gems, wigs or DIY accessories and you could have one of the most memorable looks at the party.
