For the after-party, Charli wore a sheer black lace gown by Saint Laurent. The dress featured delicate floral lacework throughout, revealing a fitted underlayer beneath while maintaining a fluid, body-skimming silhouette. A dramatically high slit ran up one side of the skirt, exposing her leg and adding sharp contrast to the otherwise romantic texture of the lace.

The combination of transparency and structure reflected Saint Laurent’s signature balance of sensuality and edge. The lace fabric featured subtle shimmering accents woven throughout, catching the light and adding dimension to the sheer construction. The gown featured a plunging neckline and full sleeves. This kept the focus on clean lines and minimal interruption to the lace detailing.

She accessorized with Saint Laurent’s “Kate” glossy burgundy patent leather clutch, finished with the house’s signature Cassandre logo. The look was completed with “Nico” black leather platform knee-high boots. The boots marked a return to a familiar favorite for Charli, as she previously wore the same style at the We Love Green festival last year.

Her beauty look followed a similarly pared-back approach. Charli wore her hair down in loose, natural waves, while her makeup leaned toward soft glam, with defined eyes and a neutral lip that complemented the monochrome palette of the outfit. The styling choice reinforced the intentional simplicity of the ensemble.

Fashion accounts shared images from the Grammys after-party on Instagram, confirming the look as Saint Laurent and highlighting the extreme slit and sheer lace construction. The appearance underscored Charli XCX’s ongoing relationship with fashion that embraces provocation, as she continues to merge her musical identity with bold, editorial dressing at major events.
