Halloween has become pop music’s favourite fancy-dress contest, and the Halloween 2026 costumes unveiled this year did not disappoint. From stadium stages to social media feeds, some of the biggest names in music used the spooky season to transform themselves into icons, superheroes and storybook characters, giving fans a fresh round of viral moments to argue about.
Harry Styles Brings Elvis Back to Madison Square Garden
The headline act of the weekend was Harry Styles, who opened his now-traditional “Harryween” shows at Madison Square Garden on October 30 dressed as Elvis Presley. Performing as part of his Together, Together residency, Styles wore a black leather jacket and the King’s signature pompadour, leaning into the rock and roll tribute with obvious affection. The Elvis look is classic Harryween territory for the singer, who has built the Halloween concerts into a fixture of his live calendar, and fans flooded social media with clips within minutes of the first song.
Halloween 2026 Costumes: Mermaids, Superheroes and Marie Antoinette
Elsewhere, BLACKPINK’s LISA took the opposite route with a shimmering mermaid-inspired look that turned her Halloween into an underwater fantasy. Girl group KATSEYE coordinated as a team, arriving in DC Comics-inspired costumes during the Halloween soundcheck of their WildWorld tour stop in Montreal, while Olivia Rodrigo, midway through her Unraveled tour, channelled Marie Antoinette for her Columbus show, complete with a powdered, courtly silhouette. Tyla opted for playful over regal, performing as a bunny while her dancers joined in as cats during her A*POP world tour.
Why Halloween Became a Music Marketing Moment
There is strategy behind the sequins. Halloween costumes give artists a ready-made viral moment in the middle of touring cycles, generating photography and short clips that travel far beyond the arena. As the full Halloween 2026 costume round-up shows, the holiday now functions almost like a second awards season for pop stars, where the prize is attention rather than trophies. Fans, meanwhile, treat the reveals as an annual ritual, rating looks and recreating favourites at their own parties. Readers who follow more celebrity and entertainment coverage will know the costume reveals now anchor the entertainment calendar every October.
With the celebrations still rolling through concerts and parties this weekend, more transformations are sure to surface. But Styles’ Elvis, LISA’s mermaid and KATSEYE’s superhero squad have already set the bar for Halloween 2026 — and given next year’s hopefuls something to top.
