How to buy cashmere: labels, knit and care

Choose the shape you want first. A fine crew neck under a jacket and a broad, textured sweater ask different things of the same fibre.

Quick facts

• Labels: read 2 kinds of information, fibre content and care instructions
• Inspection: start at 3 places, the cuffs, hem and seams
• Yarn: 2 ply means 2 strands twisted together
• Photograph: 1 Chrome Hearts sweater below, photographed by Utopia
• Source check: 3 October 2026 for the references and product photograph

Read what the label actually promises

A fibre label describes composition. A claim of 100% cashmere does not tell you the sweater's fit, construction or future condition. Ask for a clear label photograph when shopping online.

The FTC's cashmere definition concerns the fine, dehaired undercoat of a cashmere goat. For US labelling, average fibre diameter must be no greater than 19 microns. It also limits the coarser fibres and the variation in diameter.

No more than 3% by weight may consist of cashmere fibres with average diameters above 30 microns. The coefficient of variation around the mean must not exceed 24%. These are identification limits, not a promise of softness or years of wear.

If a seller gives a fibre diameter or staple length, ask what measurement supports it. A hand on the sleeve cannot establish either number. A photograph cannot do it either.

Inspect the garment without pulling it out of shape

Look at the cuffs, hem and seams for damage, uneven joins or areas you want the seller to explain. Ask for close photographs of those places on a used sweater. Check the neck opening and sleeve length against a knit you already enjoy wearing.

Our earlier advice to stretch a cuff by 2 inches and time its return was unsupported. A quick stretch is not a validated forecast of pilling or lifespan. Handle the sweater gently.

The Johnstons of Elgin glossary explains ply as the number of strands twisted together. Two ply tells you there are 2 strands. It does not tell you how the whole garment will fit or wear.

Gauge describes the knit: a higher gauge gives a finer fabric, while a lower gauge gives a thicker one. Treat those descriptions as help choosing the weight and texture you want. There is no single correct weight for every cashmere sweater.

Look at the photograph, then ask for what is missing

Chrome Hearts Cashmere Cross Patch Knit Sweater. Photograph: Utopia.

Utopia's photograph of this Chrome Hearts sweater shows a textured grey body, ribbed edges and black crosses along the sleeves. The shoulder joins sit beyond the neck opening, giving the upper body a broad shape. The contrast between the grey knit and black patches is the reason to choose this piece.

I would pair it with plain black trousers and let the sleeves remain visible. Before choosing a coat, compare its sleeve space with the sweater's measurements. The winter coat guide covers the outer layer.

The boutique's listing names cashmere, but this photograph does not establish fibre percentage, patch material or washing instructions. Ask for the sewn labels before deciding how to clean it. This is an examination of the photograph, not a wear test.

Spend for a piece you want to wear

N.Peal's buying guide cautions that price alone does not establish quality. Our former price bands attached precise lifespans to sweaters without supporting wear tests. Those promises have been removed.

Compare specific garments: composition, dimensions, condition, care instructions and the seller's return terms. Decide which difference matters to you before paying more. The winter knitwear selection lets you compare shapes and textures across individual listings.

Buy the sweater you want to wear, with care instructions you can follow.

Follow the care label on the piece

Johnstons of Elgin's care advice directs readers to the instructions sewn into each garment. For its washable cashmere knitwear, it describes gentle washing without rubbing, wringing or stretching. It recommends reshaping the knit and drying it flat, away from direct heat.

The same guide recommends dry cleaning for its woven cashmere scarves and throws. That distinction matters: one fibre name does not make every item suitable for the same cleaning method. Ask the maker about missing or unclear instructions, especially on pieces with trims or patches.

Loose fibres can tangle into pills where the garment rubs during wear. Johnstons recommends careful removal with a cashmere comb or by hand. Removing the current pills does not guarantee they will never return.

Common questions

How can you tell if cashmere is good quality?

Inspect the labels, construction and condition together; touch alone cannot establish cashmere quality or lifespan. Ask for clear photographs and support for any fibre measurements the seller advertises. Check the fit and care instructions before buying.

How much should a good cashmere sweater cost?

There is no price that guarantees a cashmere sweater's quality or lifespan. Compare the exact garments, their condition and the information each seller supplies. Treat a promised number of winters as a claim that needs evidence.

Why does my cashmere pill?

Loose fibres tangle into pills as the garment rubs during wear. Some early pilling can occur on new cashmere, so its presence alone does not prove poor quality. Follow the maker's removal advice and ask about excessive pilling.
