COS Belts Resale Value

COS belts: 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 belt, whatever the label

Belts are simple and durable, so the buckle and the leather quality carry the value.

• Full-grain leather over bonded
• Designer buckles with clear branding
• Undamaged holes with no tearing
• Recognised makers and heritage labels

And what pulls one down

• Bonded leather, which cracks and flakes
• Torn or stretched holes
• Scratched or plated buckles showing base metal
• Cracking across the fold

Working out what yours is worth

1. Measure from the buckle to the middle hole and state it
2. Flex the leather and check for cracking
3. Photograph the buckle front and back

What to state in the listing

• Size measured buckle to middle hole, and total length
• Width in millimetres, and whether it fits belt loops of a given size
• Material and buckle type, including whether the buckle is removable
• Condition of the fold, the holes and the keeper loop

Material, size and buckle: “Leather Belt, 36in, Silver Buckle, Full Grain”. The buckle-to-middle-hole size is the number buyers need. Say full grain, genuine leather or synthetic — those terms mean quite different things and buyers who know that pay accordingly.

Preparing and photographing it

1. Measure from the inside of the buckle to the middle hole, in inches and centimetres. That is the size.
2. Check the leather at the fold behind the buckle, which is where belts crack and eventually break.
3. Check the buckle for plating loss and the keeper loop, which is frequently missing.

1. The belt laid out straight, full length, whole
2. The buckle close up, front and back
3. A tape from the buckle to the middle hole
4. The fold behind the buckle, plus any crack, worn hole or plating loss

When it sells best, and handing it over

Steady year round with a lift before Christmas and Father’s Day. Designer belts sell quickly; unbranded belts compete on price.

Very cheap to post. Coil it loosely rather than folding, since a hard fold in leather leaves a permanent crease.

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 belt worth?

Roughly £6 to £35 depending on condition, against £6 to £35 for belts 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 belt, 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.
