COS Wool Jumpers Resale Value

COS wool jumpers: price by condition

Seller-declared grades, sterling with an approximate US dollar equivalent at £1 ≈ $1.33 (July 2026). What each grade means.

What holds its value across COS

• 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

What pulls COS resale value 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

1. 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
2. COS sizing runs large and is cut deliberately oversized, so give flat measurements — buyers who have not worn the label before consistently order wrong
3. Photograph the shoulder seams and the inside of the coat, because the construction is most of why somebody chooses this label secondhand

What lifts any wool jumper, whatever the label

Wool knitwear is judged on how it has been washed, since one hot wash permanently ends a jumper’s life.

• Merino, lambswool and heavier gauge knits
• No felting or shrinkage
• De-pilled surface with even texture
• Recognised knitwear brands

And what pulls one down

• Felting from a hot wash, which cannot be undone
• Moth holes, common in stored wool
• Stretched cuffs and hems
• Heavy pilling under the arms

Working out what yours is worth

1. Hold it to the light to reveal moth damage
2. Check the cuffs recover after stretching
3. De-pill it before photographing

What to state in the listing

• Exact fibre and percentage, and the knit weight
• Pit-to-pit and body length laid flat
• Number and size of any moth holes
• Neckline style and whether the ribbing has stretched

Fibre, style and size: “100% Lambswool Crew Neck Jumper, Forest Green, Size M”. Name the specific wool — merino, lambswool and shetland are searched separately and priced differently. Say if it is a recognised knitwear brand.

Preparing and photographing it

1. Hold it to the light and check for moth holes, which are small, round and easy to miss indoors.
2. De-pill the surface, particularly under the arms and at the cuffs.
3. Read the composition and note whether it is lambswool, merino, shetland or a blend.

1. Laid flat, front, on a contrasting surface
2. The composition label
3. The knit surface after de-pilling
4. Any hole or thin patch, against a light background so the size is clear

When it sells best, and handing it over

October through February with a Christmas peak. Natural fibre jumpers hold value all winter; synthetics do not.

Light and compact. Fold with tissue and use a waterproof bag, since wool absorbs any damp in transit.

What buyers ask

Does COS clothing hold its value?

Reasonably, and better than most of the high street, because the designs are plain enough not to date. Coats and tailoring do best; plain jersey basics are barely worth listing on their own.

What size should I list a COS coat as?

Give the label size and the flat measurements together. COS is cut oversized and the label size alone misleads more buyers on this brand than on almost any other.

How much is a COS wool jumper worth?

Roughly £12 to £55 depending on condition, against £12 to £55 for wool jumpers generally. The identification points above are what move a listing to the top of that range.

What the fees would take elsewhere

At the mid-range £33 for a COS wool jumper, against what the commission marketplaces would deduct:

Seller-side rates verified 26 Jul 2026, percentages only — the per-order and processing charges those platforms add are excluded, so the real gap is wider.
