COS Resale Value Guides

62 guides to what used COS is worth — the price at each condition grade, which lines hold their value, and how to date or identify what you have. COS is the quiet end of the same group that owns H&M, and its resale reflects that: plain, well-cut pieces that date slowly and sell steadily rather than spectacularly.

Which COS pieces hold their value

Oversized wool and wool-blend coats, which are the label’s signature and the thing buyers search it for by name
Archive and limited-edition pieces, which are produced in small runs and are the only part of the range with a collectors’ element
Plain, structured tailoring in neutral colours, which dates far more slowly than anything printed and stays saleable for years
Heavier knitwear in merino and wool blends, which holds its shape where the cheaper high-street equivalents do not

And what pulls the price down

Pilled knitwear, which is the commonest fault and shows immediately against the plain colours the label favours
Faded blacks and washed-out greys, which are most of the range and where fading is most obvious
Anything with a broken or replaced signature button or fastening, since the hardware is deliberately minimal and any substitute shows
Basic jersey pieces, which are cheap enough new that a used one rarely justifies the postage on its own

Identifying and dating yours

These are the checks that decide which end of the range a piece sits in, and they are the facts a serious buyer will ask for:

The neck label reads COS rather than any sub-line, and the care label carries a product code buyers can search to confirm the season
COS sizing runs large and is cut deliberately oversized, so give flat measurements — buyers who have not worn the label before consistently order wrong
Photograph the shoulder seams and the inside of the coat, because the construction is most of why somebody chooses this label secondhand

WishThrift does not authenticate or inspect anything. Condition and origin are described by the seller against five grades — what each one means — so photograph the markings above rather than asserting them.

Frequently asked questions

Is used COS worth buying?

It depends far more on the line than the label. COS is the quiet end of the same group that owns H&M, and its resale reflects that: plain, well-cut pieces that date slowly and sell steadily rather than spectacularly. Each guide below says which COS lines hold their value for that item and which have almost none, so you are comparing like for like rather than paying for the name alone.

How do I check a piece is genuine COS?

The neck label reads COS rather than any sub-line, and the care label carries a product code buyers can search to confirm the season. WishThrift does not authenticate, inspect or grade anything — condition and origin are described by the seller, so ask directly and expect an answer. A seller who has the item will send a photograph of the marking in minutes.
