Sienna Miller was seen leaving the filming of “Jimmy Kimmel Live” on June 24, dressed head-to-toe in the Chloé Resort 2025 collection as she made her way to the premiere of “Horizon: An American Saga – Chapter 1” at Regency Village Theatre in Los Angeles.

Following her appearance on the show, Miller opted for a pair of slouchy, black leather knee-high boots from the Paris-based design house. These boots feature slouchy glossy leather uppers that transition into sharp rectangular toes and 2 to 3-inch block heels crafted from half-painted wood, transitioning from black to tan. The block heels provided a practical but noticeable lift.

Miller, who plays Frances Kittredge in the post-Civil War drama directed by Kevin Costner, star donned a breezy white maxi dress in a subtly sheer fabric, also from Chloé’s resort collection. The design featured a strappy bodice and a structured silhouette.

Her outfit encapsulates the opulent, bohemian mood of the house’s resort 2025 collection, inspired by Karl Lagerfeld’s Saint-Sulpice apartment and Andy Warhol’s Factory. This collection, known for its blend of colors and textures, reflects the bohemian elegance of the era, exemplified by models such as Pat Cleveland, Jane Forth, and Donna Jordan. This fusion of eclectic style was further highlighted by the star’s choice of chunky gold jewelry, echoing the textures and colors that defined the period.

Miller’s effortless bohemian style is renowned in the fashion industry. The actress and model regularly wears boots in varying textures and heights from numerous brands, including Charles & Keith and Ganni, as well as slides by Tory Burch and Rag & Bone.
