When it comes to the classics, you can always rely on Marks & Spencer. Long my go-to for new season essentials, I couldn't wait to try on their new autumn collection, which includes a highly covetable capsule assembled by none other than Sienna Miller. Reader, they did not disappoint.
This season, the collection feels especially well curated, with effortless styles that you can mix-and-match into a full wardrobe of autumn looks for day and night, work and weekends. In fact, the latest drop from the stalwart of British style is brimming with so many good pieces, it's hard to pick out just a few favourites. Of course, at the top of my list are those that Sienna modelled in the Anything but Ordinary campaign, including cosy cable-knit jumpers, sleek tailoring and relaxed slip skirts. Any opportunity to emulate her style, I'm sold.
As someone who leans towards a more minimalist aesthetic, M&S is one of my favourite high street spots for understated essentials, and I still think they have some of the best cashmere on the high street. From slouchy crewneck jumpers to supremely on trend loafers, there are plenty of timeless pieces that I know I'd turn to again and again. From the many treasures I tried on, these 24 are at the top of my M&S wish list.
