When Sydney Sweeney steps onto the red carpet, expect the flashbulbs to go wild! Last night, the 'Anyone But You' starlet outdid herself in a jaw-dropping, backless Balmain number that screamed avant-garde chic at the Los Angeles premiere of her new scream-fest, 'Immaculate.'

Braless brilliance in Balmain

Sweeney, known for her scene-stealing roles, didn't just stop at her acting chops—she brought the drama to fashion! The sculptural top, a white Balmain creation, boasted a floral arrangement with arms wrapping around her waist, and daring peek-a-boo cutouts that revealed a bold, braless choice. "It's all about the art," she quipped, letting the top take center stage while pairing it with understated black trousers and heels.

The blonde bombshell kept her beauty game fresh and dewy, with a glossy nude-pink lip and a wet-hair look that had one tendril seductively falling across her face. "It's that effortless glam," Sydney shared, winking at the cameras.

Afterparty attire: Cardigan chic

Post-premiere, Sweeney switched up her look, slipping into a chic, ribbed white cardigan with flared cuffs and gold buttons, while keeping the same sleek pants and heels. Her beauty look remained flawless, but with a twist—she swapped her earrings for statement gold hoops.

Let's not forget the night before at the 35th annual GLAAD Media Awards, where Sweeney channeled Old Hollywood in a powder-blue Miu Miu gown with a silver crystal-embellished bra peeking out. "I love paying homage to the legends," she gushed, dazzling the crowd.
