Sienna Miller attended the premiere of her newest movie, Amazon MGM’s Tom Clancy’s Jack Ryan: Ghost Struggle, held at Regal Occasions Sq. in New York Metropolis alongside her beau, Oli Inexperienced, simply three weeks after giving beginning to her third daughter.
This will likely shock you, however I’m not really against the British actress sporting this Calvin Klein Assortment Fall 2026 gray wool pleated strapless column costume, though I do assume it’s too lengthy for her.
What me extra, nonetheless, was the general shift in course. Sienna’s fashion has lengthy been tied to the boho aesthetic she helped outline within the 2000s – all floaty clothes, fringed textures, classic references, and easy competition dressing. Even when traits moved on, she largely stayed linked to that undone method.

This Calvin Klein look suggests one thing totally different. The clear traces, architectural quantity, muted gray tone, and close to absence of embellishment level in direction of a extra minimalist method that feels worlds away from the Sienna we’re used to seeing. That will effectively clarify the appointment of Gabriella Karefa-Johnson as her stylist. Gabriella’s styling work tends to favour sharper vogue narratives over nostalgic bohemianism, and this seems like the primary actual indication that Sienna is able to evolve her picture.
I don’t assume she is going to abandon her pure ease fully, as a result of that is still central to her attraction, however there’s something refreshing about seeing her embrace a cleaner, extra directional silhouette.
The look was accomplished with sculptural silver earrings and slicked-back hair, which solely bolstered the trendy minimalism of the general styling.
Stylist: Gabriella Karefa-Johnson.
