COS Skirts Resale Value

COS skirts: 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 skirt, whatever the label

Skirts cover an enormous range, so fabric and construction quality do far more for the price than the style does.

• Natural fabrics with good weight and drape
• Lined skirts with intact linings
• Designer and contemporary labels
• Working zips and fastenings

And what pulls one down

• Torn or twisted linings
• Broken zips and missing hooks
• Pilling on woollen fabrics
• Thin unlined polyester

Working out what yours is worth

1. Check the lining is intact and hangs straight
2. Work the zip fully
3. Measure the waist and length flat

What to state in the listing

• Flat waist doubled, hip, and length from waistband to hem
• Fabric composition and whether it is lined
• Style: A-line, pencil, pleated, wrap
• Zip or elastic fastening, and whether it has pockets

Style, fabric and size: “A-Line Midi Skirt, Wool Blend, Size 12, 70cm Long”. Length in centimetres belongs in the title because skirt length is entirely relative to the wearer. Say whether it is lined and whether it has pockets.

Preparing and photographing it

1. Measure the flat waist, the hip and the full length from waistband to hem.
2. Check the zip runs cleanly and whether there is a lining.
3. Look at the seat and hem for wear, pulls or marks.

1. Laid flat, front, whole skirt in frame
2. A tape running waistband to hem
3. The composition and size label
4. The zip, the lining and any snag or mark

When it sells best, and handing it over

Steady with lifts in spring and before the party season. Midi and A-line styles sell fastest.

Light and cheap to post, folds small. Fold along the existing seams and add tissue for pleats or satin, since a creased skirt photographs badly on arrival and prompts avoidable questions.

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 skirt worth?

Roughly £8 to £35 depending on condition, against £8 to £35 for skirts 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 £21 for a COS skirt, 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.
