COS Polo Shirts Resale Value

A used COS polo shirt is typically worth £6 to £30 (approximately $8 to $40), against £6 to £30 for polo shirts generally. COS is the quiet end of the same group that owns H&M, and its resale reflects that: plain, well-cut pieces that date slowly and sell steadily rather than spectacularly.

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 polo shirt, whatever the label

Polos are heavily supplied second hand, so brand and collar condition are what separate a sale from a listing that sits.

  • Recognised heritage and sportswear labels
  • Collars that still stand rather than curl
  • Pique cotton with no thinning
  • All buttons present and matching

And what pulls one down

  • Curled or misshapen collars
  • Bobbling on the placket and under the arms
  • Missing or replaced buttons
  • Faded logos and embroidery

Working out what yours is worth

  1. Stand the collar up and see whether it holds
  2. Check the placket buttons all match
  3. Inspect the underarms for thinning

What to state in the listing

  • Chest measured flat and length from shoulder, plus label size
  • Fabric composition and whether it is piqué or jersey
  • Fit description if the brand uses one
  • Collar condition, and any bobbling, mark or thinning

Brand, colour and size: “Ralph Lauren Polo Shirt, Navy, Size L”. Brand is most of the value in this category and buyers search it directly. Say the fit — classic, custom or slim — where the maker uses those terms, because they differ significantly.

Preparing and photographing it

  1. Check the collar sits flat. A collar that has curled from washing cannot be reliably restored and must be shown honestly.
  2. Look at the placket buttons and the underarm area for thinning and staining.
  3. Iron the collar and placket before photographing — ten seconds of work that changes the photograph entirely.
  1. The shirt laid flat, front, collar arranged naturally
  2. The collar close up, showing whether it lies flat
  3. The placket buttons and cuffs
  4. The label with brand and size, plus any mark, bobbling or thinning

When it sells best, and handing it over

Lifts from April to August. Branded polos sell year round; unbranded ones are seasonal and best bundled.

Very cheap to post. Fold with the collar supported so it arrives flat rather than creased across the collar stand.

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 polo shirt worth?

Roughly £6 to £30 depending on condition, against £6 to £30 for polo 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 £18 for a COS polo 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.
