Meanwhile, BLACKPINK’s LISA took a completely different approach, embracing a mermaid-inspired look that gave her Halloween celebration an aquatic twist. The elaborate costume stood out for its fantasy elements and striking visual details.

KATSEYE also turned Halloween into a group celebration, coordinating DC Comics-inspired costumes during the Halloween soundcheck of their WildWorld Tour in Montreal. Daniela stepped into Wonder Woman’s iconic outfit, Megan became Poison Ivy, Lara transformed into Catwoman and Yoonchae embraced Harley Quinn. The group’s coordinated choices brought four recognizable comic-book characters together, giving fans another memorable moment from the tour.

Olivia Rodrigo celebrated the holiday while continuing her Unraveled Tour, channeling Marie Antoinette during her Columbus show. Her ornate, period-inspired ensemble offered a theatrical take on the historical figure. Tyla went for a more playful concept during a stop on her A*POP World Tour, dressing as a bunny while her dancers joined the theme as cats.

Chloe Bailey, meanwhile, drew inspiration from Family Guy, recreating the internet’s familiar comparison between her and a grown-up, glamorous version of Meg Griffin. Her Hot Meg costume featured a pink beanie, round glasses, a pink bra top, denim mini skirt and silver boots.

With Halloween celebrations continuing across concerts, parties and social media, these costumes offered another reminder of how artists use the holiday to experiment with their public personas.
