Sydney Sweeney brought pure fairy-tale glamour to the 2025 London Film Festival, stepping onto the red carpet in a breathtaking custom pink silk and lace gown by Alexander McQueen.

Styled by Molly Dickson, Sweeney’s gown featured a structured corset bodice with a strapless ruched bust line, creating an elegant empire-style silhouette. From the short, tailored base, a floor-length lace skirt cascaded into soft gathers, giving the gown movement and ethereal flow. What made the look even more striking was the matching V-neck lace top, seamlessly layered beneath the bustier, creating a “dress-within-a-dress” illusion that merged classic couture with modern detailing.

The pastel pink tone, accentuated by the gown’s delicate lace texture, perfectly complemented Sweeney’s luminous skin and signature blonde waves. For accessories, she kept things refined — diamond drop earrings and silver heels that peeked through the gown’s lace folds. Her makeup channeled soft glam with blush tones, rosy lips, and a touch of shimmer across the eyes, enhancing the gown’s romantic palette.

The star, who plays 1990s boxer Christy Martin in her new biopic Christy, shared with fans that she would be heading straight from the London premiere to begin filming the long-awaited third season of Euphoria. The announcement sent fans into a frenzy, but for the night, Sweeney’s regal appearance stole the spotlight — a testament to her ability to balance Hollywood power and timeless femininity.

Sweeney’s McQueen moment marked the perfect finale to her Christy press tour, cementing her position as one of red carpet fashion’s reigning stars.
