Sienna Miller’s new collection for M&S offers versatile and stylish looks for all the season’s occasions.
We’ve been longing for Sienna Miller’s wardrobe for years, and now it’s easier than ever to shop her style. Recently named the new face of Marks & Spencer for autumn/winter 2023, this week the actress unveiled a beautiful collection with the retail chain.
In the campaign, you can see Sienna showcasing a selection of elegant and versatile pieces, including her favorite: the tweed jacket. Designed to be mixed and matched in many ways, each piece can be worn separately with other wardrobe staples or together as stunning head-to-toe looks.

The collection focuses on the idea of dressing elegantly yet affordably, which aligns with the way Sienna naturally selects her own outfits, whether for taking the kids to school or for the red carpet. As the epitome of the modern woman, the collection reflects that and features everything from outerwear to chic tailoring, cozy knitwear, and eye-catching accessories.

“Sienna’s impeccable sense of style and her innate ability to make a statement through fashion make her the perfect choice for M&S. Her unique style and personality perfectly complement our brand values,” says Maddy Evans, M&S Women’s Fashion Director.
Worn in layers, these pieces also offer perfect wardrobe options for transitioning into the colder winter months.
