M&S has some famous fans, too, including none other than style icon and actor Sienna Miller – who was recently announced as the face of the brand's autumn/winter campaign. The new collection features plenty of Sienna-approved staples, including blazers, knits, waistcoats and cosy coats.

Alongside its core collection, Marks & Sparks carries over 30 brands - most of which are dedicated womenswear labels. Some of our favourites include Nobody's Child, Dune, Hobbs and Jaeger.

And while M&S clothing is certainly top tier – its wide-leg trousers and layering options are amongst some of the best on the high street, IMO – don't ever overlook the shoes and accessories, where you'll find everything from chunky loafers to of-the-moment wedge boots or the perfect crossbody bag for autumn/winter.

Psst! Don't forget to save when you shop for Marks & Spencer clothing with these Marks & Spencer discount codes.
