Sienna Miller x Marks & Spencer has launched, with the much-loved actress fronting the new autumn/winter fashion campaign for the high-street British brand. The collection named, 'Anything but ordinary', is packed full of chic new season buys, and we've rounded up our favourites to help you navigate top picks.

A new ambassador for the brand, Sienna Miller has teamed up with British clothing brand, Marks & Spencer to launch their autumn/winter fashion collection for 2023. The edit, which is now available to buy, has everything you need to up your autumn outfit ideas. Giving a nod to Miller's enviable, nonchalant, cool girl style, expect softly tailored separates, sumptuous knits, and statement knits, underpinned by directional staples such as wide leg trousers.

A master at high-low dressing, Sienna Miller is the perfect partner for this collection as it plays to her own enviable style strengths, for elevated daywear, giving even the most laidback of looks a slightly more polished feel. Giving a gentle nod to this season's trends, without feeling overly trend-led, the new Marks & Spencer's collection taps into dopamine dressing and other key fashion colour trends for a directional finish. These are the nine items we want to add to our autumn capsule wardrobe stat.
