COS Cardigans Resale Value

COS cardigans: 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 cardigan, whatever the label

Cardigans are judged on the buttons and the button band, because those carry the strain and are what fails first.

• Natural fibres with good weight and drape
• All original buttons present and matching
• Button bands that lie flat with no gaping
• Recognised knitwear labels

And what pulls one down

• Missing or mismatched replacement buttons
• Stretched, gaping button bands
• Pilling on the front where it rubs
• Thin acrylic knits, which sell for very little

Working out what yours is worth

1. Count the buttons and check they all match
2. Button it fully and check the band lies flat
3. Check the composition label

What to state in the listing

• Fibre composition and knit weight
• Pit-to-pit and body length laid flat
• Whether all buttons are present and any spare included
• Any pilling, holes or stretched cuffs

Fibre, style and size: “Lambswool Button Through Cardigan, Navy, Size 12”. Fibre is the price driver and belongs first. Say whether it is chunky, fine knit or a longline, since those suit different buyers.

Preparing and photographing it

1. Check every button is present and firmly attached, and look for a spare sewn inside the placket.
2. De-pill the fabric, especially under the arms and at the cuffs.
3. Read the composition: wool, cashmere, cotton and acrylic sit at very different prices.

1. Laid flat, front, buttoned
2. The composition label
3. The buttons and buttonholes close up
4. Cuffs, elbows and any hole, pill or stretch

When it sells best, and handing it over

Autumn through late winter, with a peak before Christmas. Natural fibre cardigans hold value; acrylic ones sell cheaply.

Light and cheap to post. Fold rather than hang so the shoulders do not stretch, and use a waterproof bag for natural fibres — wool and cashmere absorb any damp in transit and arrive smelling musty, which buyers notice immediately.

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 cardigan worth?

Roughly £8 to £40 depending on condition, against £8 to £40 for cardigans 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 £24 for a COS cardigan, 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.
