Elle Fanning has received her very first Academy Award nomination for Best Supporting Actress in the movie Sentimental Value. While preparing for the historic ceremony, the actress is also promoting her new Apple TV series, Margo's Got Money Troubles, and she's channeling '90s icon Carolyn Bessette-Kennedy while conducting press.

On March 13, makeup artist Erin Ayanian Monroe shared some behind-the-scenes snaps of Fanning's outfit on Instagram with the caption, "Elle in a LBD #ellefanning #lbd #vintagebalenciaga #margosgotmoneytroubles #thenightingale."

The sleek outfit consists of a vintage Balenciaga Sleeveless Sheath Dress from 1957, constructed from boucle wool and featuring an oversize bow at the waist.

She accessorized the look with a black Jennifer Behr Cruz Headband—reminiscent of a '90s trend made popular by CBK.

For footwear, Fanning chose a pair of black patent Alexandre Birman Tita Pumps. Her beloved steel Cartier Panthère de Cartier Watch completed the smart outfit.

Following the release of Love Story, interest in Carolyn Bessette-Kennedy's style has skyrocketed. A regular accessory CBK often reached for was a wide headband, which paired perfectly with her long blonde hair and became a '90s staple for many people. As demonstrated by Fanning, the headband is most definitely back for 2026.
