Cashmere is often described in superlatives. The more useful question is: what, exactly, makes one piece better than another?
Two pieces can both be labelled “100% cashmere” and still wear very differently. One stays soft, light and composed; the other quickly looks fuzzy or loses its shape. The difference is not a secret reserved for experts. It comes down to a few material facts—and knowing which ones to ask about.
There is no universal cashmere grade
Terms such as Grade A, premium cashmere, superfine and baby cashmere are not part of one global retail grading system. They may refer to a brand’s own specification, but they do not make two garments directly comparable.
What matters more is the evidence behind the description: fibre content, fineness, fibre length, yarn quality, construction and traceability.
In the United States, the word “cashmere” has a legal definition: it must be the fine, de-haired undercoat of a cashmere goat, with an average fibre diameter of no more than 19 microns. When a product highlights cashmere, its percentage should be disclosed. That gives shoppers a dependable place to begin.
1. Start with fibre content
Look at the permanent sewn-in label, not only the swing tag or product title.
For a pure-cashmere piece, the label should say 100% cashmere. A blend is not automatically a compromise: cashmere and silk can create a lighter, more luminous knit; cashmere and wool can offer useful structure in a coat. The important thing is transparency. Every fibre and its percentage should be clear.
Be cautious with phrases such as “cashmere feel”, “cashmere touch” or “cashmere-like”. They describe a sensation, not a fibre composition.
2. Understand microns—without buying by number alone
A micron is one thousandth of a millimetre. In general, a finer cashmere fibre feels softer against the skin. Exceptional cashmere is often around 14–16 microns, while the legal definition of cashmere permits an average diameter up to 19 microns.
But micron is not a complete score. A very fine fibre can still disappoint if it has been poorly spun or made into a fragile garment. A well-made, transparent everyday cashmere with a slightly higher micron figure may be the more satisfying piece to wear.
Consider a disclosed micron figure a helpful detail—not a shortcut to quality.
3. Fibre length shapes how cashmere wears
Longer fibres generally make smoother, more stable yarns. With fewer short ends working their way to the surface, a piece may look cleaner and feel less fuzzy over time.
Fibre length is rarely printed on a retail label. This is where transparency matters: a thoughtful brand should be able to talk clearly about its material and yarn, rather than rely only on luxury language.
4. Construction is where quality becomes visible
Cashmere quality does not end with the raw fibre. Yarn twist, knit density and finishing determine how a piece drapes, recovers and lives with you.
Check whether cuffs, hems and necklines spring back gently after being stretched.
Look for even seams and a balanced surface, rather than loose loops or uneven tension.
For scarves, choose a fabric that feels supple but intentional—not thin simply for the sake of being light.
Weight is not a verdict, either. Cashmere naturally insulates by holding still air, which is why a well-made piece can feel surprisingly warm without feeling heavy.
5. Treat origin as context, not a shortcut
Cashmere can travel through several countries between fibre, spinning, dyeing and final making. A country name alone cannot prove quality. What it can do is offer context—particularly when a brand is open about where the fibre comes from and where the finished piece is made.
At Woolara, we state the material plainly: 100% cashmere of Inner Mongolia origin, created for everyday European life. We believe material facts should be as easy to find as the colour or price.
A note on pilling
Pilling is not proof that cashmere is fake, and it is not a flaw unique to cashmere. Soft natural fibres can pill in high-friction areas—under the arms, against a bag strap or beneath a seatbelt—especially during the first wears as loose surface fibres release.
Heavy, persistent pilling can point to shorter fibres, a loose construction or frequent friction. Small early pills are normal, and can be removed gently with a cashmere comb. With thoughtful care, the surface usually settles beautifully. Read our Cashmere Care guide for simple steps that help a piece last.
The question worth asking
When a product claims to be premium, ask: What can you tell me about the fibre content, yarn, construction and origin?
A good answer does not need to be theatrical. It simply needs to be specific.
Cashmere is at its best when it feels uncomplicated: warmth without bulk, softness without spectacle, and a piece you reach for often. Understanding the material facts lets you choose it with confidence.
