When we think of COS, we usually picture muted tones, clean architectural lines, and elevated basics; in short, everything you need for the perfect autumn wardrobe. Of course, one look at the brand's new-in section is proof that the brand is a dab hand at tailored coats and versatile trousers; however, it turns out that the brand is offering an excellent line-up of autumnal dresses this season. Think longer hemlines and luxuriously warm fabrics in a rich palette tailored to perfection that are perfect for a day in the office or a dinner with friends.
Whether you're on the hunt for a sleeveless maxi to layer under your blazer or an elegant slip dress for party season, you'll find it at COS. But with an extensive list on offer, where do you begin your search? I would suggest starting with the frock that's been gaining popularity amongst stylish influencers lately: the double-faced merino wool dress. While it's the now sold-out grey version that's taken over my feed, we've got our eye on the black iteration that's equally stunning. Style on its own with ballet flats, or layer it over a white T-shirt and loafers for a preppy look.

This relaxed-fit, double-faced merino wool dress is a classic COS silhouette. Cut in a modern trapeze shape with a deep V-neckline, it works perfectly on its own or layered over a T-shirt.
Apart from the usual autumn suspects, we've also noticed the rise of blush pink in the September wardrobes of many chic women. So naturally, COS is moving quickly with an array of perfect pink pieces. Case in point, the buttoned cotton mini dress, which will pair well with tights and a jumper thrown around your shoulder for the office, or under a tailored pink coat and knee-high boots for Saturday plans.

Made from lightweight cotton with a V-neckline and back ties, this soft pink dress pairs perfectly with a cosy knit, opaque tights, and ankle boots.
Another brilliant dress worth flagging is the asymmetric tie-waist silk dress. Its rich hue and flowing silk fabric make it just as wearable for autumn as for summer. Layer it under a tailored coat or chunky knit, add ankle boots, and it's perfect for any event you have coming up.

Cut from fluid mulberry silk in a rich cherry-red shade, it’s shaped with a V-neckline, curved hem, and elegant sashes that can be tied loosely to one side or fastened into a bow, a piece that feels as timeless as it is on-trend.
While the main charm of COS's minimalist dress offering is that each frock can effortlessly be dressed up or down, the latest collection is full of rich chocolate tones, muted neutrals, and versatile styles that are perfect for autumn wear.
So, we’ll leave you with one question: have we convinced you that COS dresses are truly unbeatable? We thought so. Scroll on for our top picks; your perfect autumn dress is waiting.
