Sienna Miller’s press tour for War has been an interesting one, as a result of the actress, who has been the poster woman for boho stylish for many years, has shelved that aesthetic completely.
We’ve seen her flirt with totally different types earlier than. The 2 Schiaparelli moments for Vogue World and the Cannes Film Festival photocall spring to thoughts, however then she is going to simply as rapidly return to boho glamour in Chloé for the Met Gala and the Horizon: An American Saga Cannes premiere.
However we’re few seems to be in and proceed to be in uncharted territory, with two extra seems to be arriving as Sienna made her solution to the NBC Studios for a visitor look on The Tonight Present Starring Jimmy Fallon.

Out in New York
First up was a glance from Balmain’s Fall 2026 assortment.
I really like how the look speaks to the marginally edgier course we’ve got seen from Sienna on this tour, however some is perhaps thrown by the leather-based jacket, particularly the shoulders. You’ll both discover them overwhelming on somebody so petite and really feel that somebody like Jodie Turner-Smith would have the commanding presence to hold that exaggerated form, or recognize seeing Sienna push herself this far outdoors what we’ve got come to affiliate along with her. I fall into the latter camp.
There may be additionally an attention-grabbing piece of historical past behind the jacket. That includes an asymmetrical entrance fastening and structured shoulders, the design attracts inspiration from the 1975 Air France uniform created by Pierre Balmain for the airline’s first feminine aviator.
Did she promote this look to you?
Balenciaga Nova sunglasses and Jude the Brand Mixer sandals accomplished her look.


The Tonight Present Starring Jimmy Fallon
The arrival look would have labored completely for the sit-down with the host, however Sienna turned into a classic Lou Reed 1989 tour T-shirt and classic Levi’s denims.
I really like that she went this informal, sidestepping the anticipated late-night LBD in favour of one thing with extra character. The look additionally continues the sudden course that has made this press tour so attention-grabbing.
She stored the identical Jude the Model Mixer sandals, whereas an updo and assertion necklace dressed up the classic mixture simply sufficient for tv.
Stylists: Alexandra Cronan and Kate Foley.
