Sydney Sweeney Dazzles at 'Christy' After-Party in Elegant Black Dress

Sydney Sweeney slipped into a sleek black dress, soft curls & matching heels for the Christy premiere after-party—TIFF chic.

After delivering a knockout performance at the Toronto International Film Festival premiere of Christy, Sydney Sweeney swapped her controversial pink corset gown for a timelessly elegant look at the after-party. The 27-year-old actress, who stars as pioneering boxer Christy Martin, opted for understated sophistication to celebrate the film’s debut, proving her style versatility yet again.

Sweeney wore a glamorous black dress that epitomized classic Hollywood charm. The sleek, simple silhouette allowed her natural beauty to take center stage, a sharp contrast to the intentionally creased, corseted Erdem gown she wore on the red carpet just hours earlier. She paired the dress with soft, flowing curls and a pair of matching black heels, embodying an aura of refined grace.

This style choice feels particularly significant given the context of the evening. Earlier, at the premiere, Sweeney received a thunderous standing ovation for her transformative performance, moving her to tears as she took the stage to express gratitude to the real Christy Martin, who was in attendance. The after-party look, then, was less about making a bold fashion statement and more about embodying the quiet confidence of a woman celebrating a major professional achievement.

The dress also served as a visual breather amid a recent string of high-fashion corseted looks. While she has masterfully worn designs from Wiederhoeft to Danielle Frankel, this simple black number was a reminder that Sweeney’s style doesn’t always need architectural drama to make an impact.

Sweeney’s focus remains squarely on the film, for which she underwent a grueling physical transformation, gaining over 30 pounds of muscle and performing all her own boxing stunts. When asked about recent controversies, like the American Eagle campaign, she has consistently redirected the conversation back to Christy and Christy Martin’s incredible story of survival and triumph.

Ultimately, Sydney Sweeney’s after-party ensemble was a perfect metaphor for her current career moment: powerful, polished, and entirely focused on the work.
