Sienna Miller highlights autumn fashion trends in New York

Actress Sienna Miller has highlighted key autumn fashion trends through recent street style appearances. During a press tour in New York, Miller showcased a modern take on the leather jacket, wearing a Balmain piece characterized by a cinched waist, strong shoulder pads, and a wide collar.

In a separate look, Miller demonstrated the seasonal relevance of bold red tones, pairing a red bomber jacket with white jeans and a navy knit. This use of primary color clashing and statement red accents aligns with recent Autumn/Winter 26 runway presentations from designers including Prada, Schiaparelli, Alaïa, and McQueen.
