Our take on the COS Lightweight Cotton Short-Sleeve Turtleneck

A black short-sleeve turtleneck knit top from COS, cut slim and cropped to the hip. The fine-gauge cotton knit holds a clean shape without bulk, so it layers under a blazer or jacket without bunching at the sleeves. It suits anyone building a minimalist wardrobe or wanting a polished top for work. Against a long-sleeve turtleneck it is lighter and easier to layer in warm weather; against a plain crew-neck tee it reads dressier. The narrow chest and short body mean it fits close, so check the flat measurements against a top you already own.

Questions and answers

How does this compare with a long-sleeve COS turtleneck?
It is the same fine-knit turtleneck idea with short sleeves, so it is lighter and layers under a blazer without sleeve bunching. It gives less warmth on the arms.
What is the fit like?
It is cut slim: about 14.2 inches from armpit to armpit laid flat and 23.3 inches long. Compare those to a top you own that fits well before buying.
Is it warm enough for winter?
The cotton knit is light and the sleeves are short, so it works best as a base layer under a jacket or sweater in cold weather. On its own it suits mild days.
Can it be worn to the office?
Yes. The turtleneck and clean black knit read polished under a blazer or with tailored trousers. It is casual enough for weekends too.
How should I care for the cotton knit?
Wash it gently and dry flat to keep the shape and avoid stretching. Fine cotton knits pill faster with heat and tumble drying.
Where is the COS Lightweight Cotton Short-Sleeve Turtleneck cheapest?
At Poshmark, for $125.00, as of our latest check.
