Yes, I’m Certain—This COS Jumper Is All You Need to Look Polished and Put-Together This Winter

Made from 100% wool, available in sizes XS (UK 4) to XL (UK 18), and with five versatile colours to choose from, COS’s rounded wool crew-neck jumper might only be my first purchase of the season, but it’s already set to be the smartest investment I make this winter.

With a slouchy, relaxed fit that feels effortlessly chic and laid-back, as well as a versatile rounded neckline, this is the type of knit that can easily be dressed up or down for a wide range of occasions. I invested in the black hue, and the styling possibilities are truly endless. I’ve already worn it with a pair of black barrel-leg trousers and animal-print accessories to the office as well as with a polka-dot slip skirt and kitten heels for a dinner date. Not to mention that its natural fibre composition means that it’s not only biodegradable but durable, ensuring it will last in my autumn/winter capsule for a significantly longer time than synthetic knitwear.

And the price? At £95, I appreciate you can find more affordable jumpers on the high street; however, for a versatile item that you’ll wear from now and well into early spring for many years to come, as well as the 100% wool composition, I personally think this jumper is well worth the money and genuinely rivals a number of luxury finds in this aspect. Keep scrolling to see and shop COS’s Rounded Wool Crew-Neck Jumper for yourself, and then take a browse at some more designer-passing COS jumpers I currently have my eye on.

I invested in this classic black hue for winter 2026, and it will go with everything I own.

This will pair well with neutral and bolder hues alike.

Never underestimate the elegance of a cream knit.

The cashmere crew-neck is an investment for sure, but it will last in your wardrobe forever.

Argyle knits re an easy way to add interest to an otherwise pared-back outfit.

Wear with tailored trousers and loafers to the office, then a slip skirt and kitten heels for an evening out.

It doesn’t get much more elegant than a funnel-neck jumper.

This baby blue hue will feel so fresh in winter.

Yet another COS cashmere knit I have my eye on.

A red jumper that doesn’t feel too out-there for a minimalist like me.
