Buying a Used Cashmere Sweater: What to Check

What a fair price looks like

Condition on WishThrift is described by the seller against five grades, and nobody inspects it on your behalf — so the description and the photographs are what you are buying on.

Sterling guide ranges with an approximate US dollar equivalent at £1 ≈ $1.33 (July 2026). Sellers set their own asking price; these are a starting point for judging an offer. All five grades explained.

The checklist before you pay

Sizing, above everything. A garment that does not fit is the commonest reason a second-hand clothing purchase disappoints, and it is entirely avoidable by asking for flat measurements rather than trusting the label.

Run through these before money changes hands — they are the things that decide whether a cashmere sweater is worth what is being asked:

• Moth holes, which are common and immediately visible
• Felting or shrinkage from a hot wash
• Thin single-ply knits that have gone see-through at the elbows
• Stretched cuffs and hems that no longer recover

And the things worth paying more for, because they hold their value:

• Two-ply or heavier construction with real weight to it
• No pilling, or pilling that has been properly removed
• Full-fashioned shoulders and a soft, dense handle
• Classic colours that sell in any season

Common faults and fakes

Counterfeits concentrate in a handful of premium labels and are usually given away by the internal tags rather than the outside: font weight, stitch density on the label edge, and a care label that does not match the era of the design.

Ask for a photograph of the inner label and the garment laid flat with a tape measure across the chest and the length. Both are quick for an honest seller and awkward for anyone who does not have the item in front of them.

WishThrift does not authenticate, inspect or grade anything, and no marketplace check replaces your own. If a seller will not answer a direct question about condition or origin, that is the answer.

Questions to ask the seller

These are the three that get asked most often about a cashmere sweater, and the answers tell you most of what you need:

Also worth establishing before you commit:

1. Hold the knit up to the light to reveal moth damage and thin patches
2. Check the composition label for the cashmere percentage and ply
3. De-pill it carefully before photographing

Photographs to ask for

If the listing does not already show these, ask — a seller who has the item will send them in minutes:

1. Laid flat, front, on a contrasting plain surface
2. The composition label showing the cashmere percentage and ply if stated
3. A close, well-lit shot of the knit surface after de-pilling, to prove the condition
4. Any hole, thin patch or repair, photographed against a light background so the size is clear

Details to confirm before you commit

• The exact cashmere percentage, and what the rest of the blend is
• Pit-to-pit and body length laid flat
• Whether there are any moth holes, however small, and how many
• The ply if the label states it, since two-ply wears far better than single

Live cashmere sweater listings

Nothing matching is listed at the moment. Browse clothing for what is live now, or everything on the site — stock changes daily and new listings are free to post, so it is worth checking back.

When to buy

Sells from October through February, with a clear peak before Christmas. Outside that window prices soften noticeably, so a summer listing is usually worth holding.

Prices move against that cycle for a buyer: the cheapest time to buy is when sellers are listing most, not when demand peaks.

Paying and collecting safely

WishThrift does not process payments, hold funds or offer buyer protection — you agree the price and the method with the seller directly, which is what keeps the platform free on both sides. Meet somewhere public where you can, inspect before you pay, and keep the conversation on the site so there is a record of what was agreed. Be wary of any seller who wants to move the conversation elsewhere before you have agreed anything.

Selling one instead?

If you already have a cashmere sweater sitting unused, it is free to list and there is no commission — the price you agree is the amount you keep. Read how to sell cashmere sweater for what to photograph and how to price, or what cashmere sweater is worth at each condition grade.

Frequently asked questions

What should I pay for a used cashmere sweater?

Around £13 to £58 in good condition, more for barely-used examples and less for anything with a described fault. Compare against the seller’s photographs rather than the grade alone.

How do I check a cashmere sweater before buying?

Ask for a photograph of the inner label and the garment laid flat with a tape measure across the chest and the length. Both are quick for an honest seller and awkward for anyone who does not have the item in front of them.

Is buying a cashmere sweater second hand safe?

Yes, with the ordinary care any private sale needs. WishThrift does not authenticate, inspect or hold funds, so inspect before you pay where you can, meet somewhere public, and keep the conversation on the site. Sizing, above everything. A garment that does not fit is the commonest reason a second-hand clothing purchase disappoints, and it is entirely avoidable by asking for flat measurements rather than trusting the label.
