Halloween 2026 saw a wave of imaginative celebrity costumes both onstage and across social media. Harry Styles launched his annual Harryween celebrations at Madison Square Garden on October 30, the first night of his Together, Together residency, dressed as Elvis Presley in a black leather jacket with a signature pompadour hairstyle.
BLACKPINK's LISA took a very different direction, turning heads with a mermaid-inspired look full of fantasy elements and striking aquatic details. K-pop group KATSEYE went for a coordinated DC Comics theme during the Halloween soundcheck of their WildWorld Tour stop in Montreal: Daniela portrayed Wonder Woman, Megan became Poison Ivy, Lara stepped into Catwoman's role and Yoonchae channelled Harley Quinn.
Olivia Rodrigo embraced historical drama on her Unraveled Tour, channelling Marie Antoinette at her Columbus show with an ornate, period-inspired ensemble. Tyla kept things playful on her A*POP World Tour, dressing as a bunny while her dancers dressed as cats.
Chloe Bailey drew on internet culture, recreating the widely shared comparison between herself and a glamorised version of Meg Griffin from Family Guy. Her Hot Meg costume included a pink beanie, round glasses, a pink bra top, a denim mini skirt and silver boots. Other artists spotted in costume included Faouzia as the Corpse Bride, NINGNING as a Clase Azul tequila bottle, Lily Allen as a Ticketmaster seat map, GloRilla as Ciara and Coco Jones as Mary J. Blige.
