Billie Eilish meant business in a tailored Celine look for the London premiere of her film “Hit Me Hard And Soft: The Tour” on Tuesday.

The Grammy Award-winning artist wore a curated look in dark tones and blue accents, augmenting the color theme of the event from the blue carpet to the backdrop behind Eilish as she posed for photos.

Eilish’s look was comprised of the long docks trousers from the French luxury brand and the blue silk poplin shirt. The “What Was I Made For?” songwriter also sported a piece inspired by Celine’s spring 2026 ready-to-wear collection — a double-breasted blazer with six silver buttons lining the front placket.

Eilish capped off her look with a pair of Celine’s flat sneakers and accessorized with a silver chain that could just be glimpsed beneath her jacket as well as a tie with complementing striped colorways reflected in the ensemble. Tailoring for Eilish’s attire was provided by Faye Oakenfull.

As for glam, Eilish’s hair was styled by Benjamin Mohap, founder of the West Hollywood and New York City Benjamin Salon. Makeup by artist Emily Cheng featured soft elements that spotlighted Eilish’s blue eyes. The singer’s look was curated by stylist Spencer Singer.

Known for toying with expression through style, Eilish’s streamlined Celine look merged a recent resurgence of menswear and women’s tailoring styled by famous women on the red carpet.

Prior to Eilish’s red carpet appearance in London, Charlize Theron followed the trend at the “Apex” premiere in New York City on April 22, wearing a style from Christian Dior’s men’s fall 2026 ready-to-wear collection.

The “Hit Me Hard and Soft” documentary and concert film chronicles the Manchester shows performed by Billie Eilish in July 2025 as part of her tour, with behind-the-scenes footage of Eilish putting the show together with her team. A 3D experience of the film, co-directed by Eilish and Oscar-winning “Avatar” filmmaker James Cameron, hits theaters on May 8.
