Just moments ago, Marks & Spencer made its London Fashion Week debut. The new collection celebrates 100 years of fashion at the high street powerhouse, and just as the last model exited the runway, the new collection dropped. Already, the site is alight with shoppers scouring the digital shelves for the new releases, but I have the inside scoop. Before it even hit the runway, I had the chance to try on the new collection, and I’ve already selected the pieces that are sure to make autumn dressing instantly more polished.

With a century of legacy, the new collection is a celebration of the very best of Marks & Spencer’s fashion history. From the current best-sellers of today to archival styles from decades ago, the brand is calling out the best styles, reconfigured in palettes and detailing to bring them firmly into 2026. It’s a unique position to be in to lean into the throwback trends of today and reference your own brand’s history, but that’s exactly what Marks & Spencer has done.

For autumn/winter 2026, Marks & Spencer is ticking off all the occasions in your calendar with a curated edit of polished pieces. For day, you’ll see the return of excellent denim, from sculpted barrel-leg silhouettes to classic wide-leg styles with playful twisted seams, as well as the return of the best-selling barrel trousers in a fittingly autumnal khaki hue. To ease us into the cooler months, knitwear is back in sumptuous finishes and an array of shades from minimalist neutrals to standout shades. Alongside, Marks & Spencer brings a selection of capsule wardrobe heroes to the fore, ready to work hard over the coming months, from classic long-sleeved turtleneck tops to a crisp white shirt with a cinched silhouette to bring a modern edge.

In line with autumn’s arrival, a series of sleek outerwear stepped out on the runway. Leather bomber jackets, cosy aviator jackets and sleek coats were the refined finishing touches to both day and evening looks. I had the chance to try them on, and was particularly drawn to the flight jacket that is an M&S heritage piece, brought back decades later as it’s proven to be just that timeless. Alongside, there’s the wool coat with a bold funnel-neck collar and sweet frog-fastening accents, and my eye was immediately drawn to the black faux fur coat. The silhouette is classic, with a refined finish which could easily ensure any onlooker mistakes it for designer—I certainly did.

To round off our wardrobes, Marks & Spencer turns its attention to eveningwear. Think the reinvented tuxedo, which I tried in sleek black but also comes in a tactile tweed, another reference to an archival favourite. I also tried on a sleek jumpsuit with soft pleating, and ever since this fitting I haven’t been able to stop thinking about it. The draped shape is eye-catching, comfortable and offers an instantly refined outfit for your dressier autumn plans; you simply need to add a pair of heels and grab one of the new clutch bags. Yes, you definitely need to take a peek at the sophisticated bags on offer this season.

Now, let’s get straight into the most polished pieces from the Marks & Spencer Autumn/Winter 2026 runway collection.
