Sydney Sweeney Wins Hamptons Acting Award for Boxing Biopic

At the 2025 Hamptons International Film Festival, Sydney Sweeney received an Achievement in Acting award for her lead performance in Christy, a biopic in which she underwent intense physical transformation to portray boxer Christy Martin and that is generating awards-season buzz. For the occasion she wore a vintage Thierry Mugler archival ensemble — a white deconstructed tuxedo minidress with a sheer tutu skirt, cropped blazer and bow details — styled by Molly Dickson. She began the night in Jimmy Choo heels before swapping into sneakers, accessorized with a reportedly 3-carat pink sapphire Jennifer Meyer necklace, and wore signature blonde waves with soft peachy/rosy glam. The look has archival provenance and had been seen previously on another celebrity. Her appearance reinforced Sweeney’s current high-profile run — including buzzy roles, brand deals, a recent space-themed birthday celebration and reported new romance — and kept her prominent on social media. Channeling a feminine, vintage Mugler aesthetic at a promo for a physically demanding boxing film highlighted the contrast between her off-duty style and the role’s rigorous demands.
