The development solidified Ronan's reputation as a style icon, and it happened after the Irish actor was frequently spotted donning the fashion house's creations in the past few years.

Among them was a stunning appearance in December 2023 as a guest of Nicolas Ghesquière, the brand's artistic director of women's collections, at the Academy Museum Gala in Los Angeles. Ronana most recently wore a beautiful pale blue jumpsuit design from the brand to the Sundance Film Festival.

Regarding Ronan's appointment as a brand ambassador, Ghesquière stated: "I've been a longtime admirer of Saoirse's work and find her to be utterly captivating in her roles. Furthermore, she is a really endearing and intelligent person beneath her skill."

She becomes a brand ambassador with A-lister Zendaya, who was hired in April 2023.

Ronan has long been a fan favourite when it comes to award season style. She is well-known for her red carpet designs that mix ethereal elegance with edgy and contemporary accents. She wore minimalist outfits that were remarkable for their flashes of colour or avant-garde embellishments thanks to her collaboration with stylist Elizabeth Saltzman.

Looks like we're in for a very luxurious couple of months, with Ronan producing and starring in his latest picture, The Outrun, set for release.
