Given that it's rainy, breezy and the kids are back in school, we can confirm autumn is upon us. While we're still trying to give our summer shorts a couple more weeks of life, we're also aware that we've firmly landed in transitional dressing weather, which means easy pull on-and-off jackets and jumpers to get us through the next few weeks in style and comfort. M&S is always our first port of call when it comes to long-lasting, stylish and affordable separates, and we've spotted a boxy wool-blend cardigan that looks like a Chanel jacket but costs less than £30. With over 100 reviews and a 4.6 star rating, here's why the retailer's crew neck cardigan will quickly become a wardrobe staple. © M&S Crew Neck Cardigan With Wool, £28 at M&S What is M&S's cardigan for autumn? M&S has ticked every box with this crew neck cardigan featuring 8% wool. It comes in two go-with-everything-but-not-basic-black-or-white colours: oatmeal and burgundy. The cardi is available in sizes Extra Small through Extra Large, and it has a crew neck, button front and ribbed trims at the neck, cuffs and hem. A touch of elastane gives the cardi movement and stretch. Customers say it fits a little big. The cardi's boxy shape and slightly cropped hem add to its appeal: the silhouette is universally timeless and flattering because it's a lot like a classic Chanel jacket. Except it retails for £28. © M&S Crew Neck Cardigan With Wool, £28 at M&S What do customers say about M&S's cardigan?
