Elle Fanning Serves ’60s Bombshell in Backless Gucci Gown at ‘A Complete Unknown’ Los Angeles Premiere

Elle Fanning put a sultry spin on 1960s fashion at the premiere of “A Complete Unknown” in Los Angeles on Tuesday. The actress, who portrays Bob Dylan’s girlfriend in James Mangold’s new biopic, walked the red carpet in a sleek Gucci gown with crystal embellishments.

Fanning’s backless frock featured a square neckline and a bow appliqué, emblematic of trends throughout the decade. Bedazzled hair ties and Cartier jewels — including a tennis bracelet and cocktail rings — completed her glamorous ensemble.

Stylist Samantha McMillen, who also counts John David Washington and Daisy Ridley as clients, curated Fanning’s look for the occasion.

The actress’ retro bouffant with pigtails, styled by hairdresser Jenda, evoked Brigitte Bardot, while makeup artist Erin Ayanian Monroe gave the “Maleficent” star thick winged liner and a pop of pink blush.

Fanning also went backless at the closing ceremony of the Cannes Film Festival in May, where she wore a diaphanous Gucci dress printed with daisies. It came from the Italian label’s 2025 cruise line, which made its debut in London.

On Monday, Mindy Kaling and Morris Chestnut announced the nominees for the 2025 Golden Globes. “A Complete Unknown,” starring Timothée Chalamet as Dylan, picked up three nods, including Best Performance by an Actor in a Motion Picture — Drama for Chalamet, Best Performance by a Male Actor in a Supporting Role in a Motion Picture for Edward Norton and Best Motion Picture — Drama.

Sabato De Sarno succeeded Gucci’s longtime creative director, Alessandro Michele, in 2023, giving the acclaimed fashion house a more minimalist appeal.

“He leaned into the clean, elegant daywear trend seen at Prada, among others, with 1960s-meets-1990s tailored coats, super-short-shorts and cute logo rompers and jumpers, body-skimming tanks and knit sets, baggy jeans and crystal bra tops,” wrote WWD’s Booth Moore.
