Autumn is finally here, and the only thing on my mind right now is finding some new knitwear to cosy up in from now until next spring. My first port of call? COS, of course. This high street hero is known amongst editors and fashion people as a go-to destination for designer looking knitwear that will stand the test of time on your wardrobe. And although this brand is well-known for its timeless staples that will never date, for autumn 2026 specifically, I’m on the hunt for some fresher jumper and cardigan trends that will dress up my black trousers, wide-leg jeans and simple slip skirts.
And trust me when I say that COS’ collection didn’t disappoint. From bright purple hues that will take an autumn look from basic to elevated in an instant to elegant funnel-neck silhouettes that will add an instant sense of polish to every outfit, there’s something suited to both minimalists and maximalists alike this season. And the best part? I’ve rounded up the best of the best for you below.
Keep scrolling to discover the five chic knitwear trends that COS is backing for autumn 2026 (and beyond).
5 Expensive-Looking Knitwear Trends That COS is Backing for Autumn 2026
1. Veronica Purple
Style Notes: I’ve always considered myself a classic dresser who tends to stick to neutral hues such as black or brown, but this bright purple hue that COS is backing for autumn 2026 is very much calling to me. It’s eye-catching and an easy way to add interest to an otherwise neutral outfit, but something about this colour still manages to feel extremely expensive and wearable. I’m sold.

2. Funnel-Neck
Style Notes: We’ve seen funnel neck jackets dominate the fashion scene for the past two years, and now, this elegant silhouette has made its way into knitwear as well. There’s just something about a jumper or cardigan with this neckline that feels inherently polished not to mention that it’s the perfect way to keep you warm on the chillier autumn days.

4. Layered
Style Notes: I was obsessed with the raglan tee trend that COS backed this spring, and the layered knitwear is the perfect follow on from this. The perfect everyday throw-on style, this elevated staple is the perfect addition to any trousers, skirts or jeans this season. Not to mention that COS has a wide selection of these knits on offer, from pared-back neutrals that minimal dressers will appreciate to bolder hues that the bolder fashion people will love.

5. Forest Green
Style Notes: Similar to navy, forest green hues feel different enough from black or brown to add one interest to an outfit, but still manage to be just a versatile and timeless as these neutral colours. Working well with both pared-back and bold colours alike, this is a knitwear colour trend that will still remain wearable in the autumns to come.
