Sienna Miller is new face of M&S

Over the past two decades, Sienna Miller has been synonymous as an iconic style trendsetter, so it comes as no surprise that the actress has become the latest face of M&S.

Miller's collaboration with M&S reflects easy-to-wear essentials, seasonal separates like oversized blazers, tailored waistcoats, and wide-leg trousers, along with statement pieces that will breathe new life into your wardrobe.

Our personal favourite from the collection is the red gingham coat, which is paired with a belt to give a waist-cinching silhouette.

Speaking about the collaboration, Sienna said: “I have always had a genuine love for Marks & Spencer, a brand that holds special associations for so many people.

“I am thrilled to be joining this iconic company, fronting their autumn campaign and being a part of their journey in shaping the future of fashion.”
