COS Jeans Resale Value

COS jeans: 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 jeans, whatever the label

Everyday jeans sell for small sums, but vintage and selvedge denim is collected seriously and prices reflect that.

• Selvedge denim, visible at the outseam
• Genuine vintage production with period hardware
• Natural fading that follows real wear
• Uncommon cuts and sizes in demand

And what pulls one down

• Crotch blowouts and thigh wear
• Faded from storage rather than wear
• Altered hems that shorten the leg permanently
• Fast-fashion jeans, which sell for very little

Working out what yours is worth

1. Turn the outseam out and look for a selvedge line
2. Check the inner tag for production details and origin
3. Measure the actual waist and inseam rather than trusting the label

What to state in the listing

• Flat waist measured across and doubled, in inches
• Inside leg from crotch seam to hem, and whether they have been shortened
• The rise — high, mid or low — which decides the whole look and is rarely stated
• Fabric composition, particularly the elastane percentage, since stretch changes the fit entirely

Brand, cut, then size, in that order, because that is exactly how buyers search: “Levi’s 501 Straight Jeans, W32 L34, Mid Blue”. Never rely on the label size alone — put the measured waist in the description, and say if they have been hemmed, because an altered inseam is the most common cause of a disappointed buyer.

Preparing and photographing it

1. Wash and dry them as you normally would, so the measurements you take reflect how they will arrive.
2. Check the crotch seam and inner thigh, which is where jeans wear through and where buyers will look first.
3. Read the tab and the internal tag for the exact cut name — 501, Slim Straight, Bootcut — and the fabric composition.

1. Front, laid flat and smoothed, with the whole leg in frame
2. Back, showing the pocket stitching and any fading or wear on the seat
3. The waistband tag showing brand, size and cut
4. A measuring tape across the flat waist, plus any wear at the hem or crotch

When it sells best, and handing it over

Steady all year with no real season. Common sizes in recognised brands sell within a week or two; unusual leg lengths take longer but attract buyers who are specifically hunting and haggle less.

Cheap and easy to post, which makes jeans one of the best items to sell to buyers outside your area. Roll rather than fold to keep the parcel small.

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 are COS jeans worth?

Roughly £10 to £45 depending on condition, against £10 to £45 for jeans 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 £27 for COS jeans, 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.
