Sienna Miller’s M&S collection is capsule wardrobe perfection

Recently named Marks & Spencer’s new face of fashion for AW23, this week the actor unveiled a beautiful Anything but Ordinary collection with the high street retailer. 

Across the campaign, Sienna can be seen wearing a selection of stylish and versatile pieces, including Sienna’s favourite piece – the tweed blazer. Designed to be styled in myriad ways, each piece can be worn individually with other wardrobe staples or together as head-to-toe statement looks. 

High/low dressing is at the heart of the collection, which is right on brand for how Sienna naturally picks her own looks – be that for the school run or the red carpet. The epitome of the modern woman, the collection is very much a reflection of that and features everything from outerwear to smart tailoring pieces, chunky knitwear and statement accessories.

“Sienna’s impeccable sense of style and innate ability to make a statement through fashion makes her the perfect fit for M&S. Her unique style and personality perfectly complements our brand values,” notes Maddy Evans, M&S Womenswear Director.

Layered up, these pieces also provide the perfect transitional outfitting options as we move into the cooler winter months.

Available online and in stores now, we’ve rounded up some of our favourite pieces below.
