Saturday night in Los Angeles, the pop stars came out in full force to commemorate National PrEP Day hosted at The Abbey. Kesha, Demi Lovato and more celebrated MISTR’s continued efforts to promote HIV prevention, educate, reduce the stigma and expand online access to PrEP, which helps those who are HIV-negative from contracting the virus.

While Lovato and Kesha embraced the boudoir and a touch of the wild, other attendees like Charli XCX, Tinashe and Christina Aguilera brought their signature style to the red — in this case blue — carpet. WWD breaks down those looks and more ahead.

Demi Lovato

Demi Lovato brought boudoir-inspired styling to the arrival carpet at The Abbey in a look by Fanci Club. The “Cool for the Summer” singer wore a corseted minidress with the bodice cast in contrasting tones of red and aubergine.

Christina Aguilera

Christina Aguilera harkened back to her “Dirrty” era with her look. The Grammy Award-winning singer wore a sheer Didu black cross mesh top over a black leather bra top and a pair of Dilara Findikoglu leather short-shorts with lace-up detailing. She completed the look with thigh-high Christian Louboutin Circus Max Botta Alta boots.

Tinashe

Tinashe went for sheer styling with a playful ’90s pop star vibe in her Erik Charlotte look. The coordinated blue lace sheer blouse and skirt ensemble hailed from the spring 2027 collection, with Tinashe following the recent trend of celebrities eschewing fall staples for the spring 2027 runways.

Kesha

Kesha embraced her wild side with a leopard print semi-sheer dress. The maxi look included a high neckline with sleeves so long they went over the “Die Young” artist’s fingertips. Transitioning from formfitting to a more A-line design, the skirt of the dress included some movement.

Charli XCX

Charli XCX brought goth glam in full force on Saturday night in her custom Julia O’Callaghan ensemble. The look featured short-shorts with an open, semi-sheer tiered cape with ruffle elements. She punctuated the all-black look with platform pumps.
