Although Sydney Sweeney is set to portray a boxer in an upcoming biopic, her outfit at the Hamptons International Film Festival this week dramatically diverted from that image, opting instead for the look of a figure skater.
On October 4, during a promotional appearance for her film Christy—which has already sparked awards season excitement after its initial screenings—Sweeney wore a stunning vintage Thierry Mugler mini-dress paired with Jimmy Choo heels. The eye-catching dress featured a bow-adorned bustier with a fitted waist and a tulle tutu skirt, complemented by a matching cropped white blazer.
Accessorizing her look, she donned a delicate gold necklace and styled her long blonde hair in loose waves—more suited for a gala than a boxing ring or an ice rink, but undeniably charming.

Styled by Molly Dickson, Sweeney has made a statement this week with her bold fashion choices. Celebrating her birthday recently, she donned a custom creation by The Blonds, inspired by a galactic outfit worn by Britney Spears. The collaboration between Dickson and Sweeney has delivered a feminine aesthetic, richly detailed, drawing influence from vintage Mugler, Versace, and JPG, alongside modern designs like custom Erdem, nautical Coperni, and sharp tailored looks from Monse. Sweeney’s playful, princess-like red carpet personas have been on full display during her Echo Valley promotional tour, where she shimmered in a fitted archival Elie Saab gown, a corseted McQueen top, and a crystal-encrusted bodice by McQueen. Earlier this year, Sweeney turned heads in an ultra cinched Wiederhoeft dress from the designer’s spring 2025 collection while promoting her film The Housemaid at CinemaCon.
In Christy, Sweeney embodies the legendary boxer Christy Salters Martin, chronicling her ascent in the boxing world of the 1980s, while also confronting personal challenges and hardships. According to Sweeney, this role demanded an intense commitment, involving countless hours of training with a boxing coach and strength trainers. This recent shift towards softer, more romantic wardrobe choices appears to encapsulate Sydney Sweeney’s multifaceted style evolution.
