COS Blouses Resale Value

COS blouses: 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 blouse, whatever the label

Blouses cover everything from silk designer pieces to polyester basics, and the fabric label tells you which market you are in.

• Silk and quality natural fibres
• Designer and contemporary labels
• Intact seams and working closures
• No underarm marks or deodorant damage

And what pulls one down

• Underarm staining, which is often permanent on silk
• Snags and pulls in delicate fabric
• Missing buttons and broken closures
• Polyester basics, which sell for very little

Working out what yours is worth

1. Check the underarms in daylight
2. Hold the fabric to the light for snags and thinning
3. Read the composition label

What to state in the listing

• Bust, waist, shoulder and length measured flat
• Fabric composition and whether it is lined
• Whether the fabric is sheer
• Sleeve length and neckline, and any mark or snag

Fabric, style and size: “Silk Button Through Blouse, Cream, Size 10”. Fibre is the price driver — silk, viscose and polyester sit at very different levels. Say whether it is sheer, because that decides whether the buyer needs something underneath.

Preparing and photographing it

1. Measure bust, waist, shoulder and length laid flat.
2. Check for underarm marks and deodorant staining, which is the most common reason a blouse is unsellable.
3. Hold it to the light and check whether it is sheer, and whether it is lined.

1. Laid flat or on a hanger, front, whole garment
2. The fabric close up, showing texture and pattern accurately
3. The composition label
4. The underarms, buttons and any mark, snag or pull

When it sells best, and handing it over

Steady with a lift in spring and before the party season. Silk and quality viscose sell fastest.

Very light and cheap to post. Fold with tissue in the creases for silk and delicate fabrics.

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 blouse worth?

Roughly £8 to £38 depending on condition, against £8 to £38 for blouses 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 £23 for a COS blouse, 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.
