COS Denim Shirts Resale Value

COS denim shirts: 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 denim shirt, whatever the label

Denim shirts follow the same logic as denim jackets: genuine age and selvedge construction add value rather than removing it.

• Selvedge denim visible at the placket or side seam
• Genuine vintage with period snaps or buttons
• Natural fading following real wear
• Recognised denim labels

And what pulls one down

• Fraying at the collar points and cuffs
• Replaced buttons or snaps
• Artificial distressing
• Thin, lightweight modern chambray sold as denim

Working out what yours is worth

1. Check the side seam or placket for a selvedge line
2. Inspect the collar points and cuffs
3. Photograph the buttons or snaps close up

What to state in the listing

• Chest and length measured flat, plus label size
• Wash depth — light, mid, dark or black
• Whether the fastenings are buttons or press studs
• Fabric weight and whether it has any stretch

Brand, wash and size: “Levi’s Denim Shirt, Light Wash, Size M, Western Snaps”. Wash depth is a real search and photographs misrepresent denim colour badly, so state it. Western press studs versus plain buttons is a genuine style distinction.

Preparing and photographing it

1. Wash only if it genuinely needs it, since washing flattens the fade that makes a denim shirt desirable.
2. Check the collar points, cuffs and elbows, which is where denim shirts wear through.
3. Check every button and snap, and note whether the fastenings are buttons or press studs.

1. The shirt flat, front, whole, in daylight
2. The back and the yoke, where fading shows most
3. The collar points and cuffs
4. The label with brand and size, plus any fray, hole or repair

When it sells best, and handing it over

Steady year round with a lift in spring and autumn. Recognised denim brands sell within a fortnight.

Light and cheap to post. Fold along the seams and it arrives ready to wear with minimal creasing.

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 denim shirt worth?

Roughly £8 to £32 depending on condition, against £8 to £32 for denim shirts 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 £20 for a COS denim shirt, 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.
