The short answer
A pure cashmere suit is worth it only as an occasional winter suit: it is softer and warmer than wool but pills, shines and wears at the seat and elbows much sooner. A wool-cashmere blend, commonly 5 or 10 percent cashmere, keeps most of wool's durability and adds softness. Cashmere is at its best in sport coats and overcoats, which see little friction.
- Cashmere is the fine undercoat of the cashmere goat; US law caps its average fiber diameter at 19 microns.
- Pure cashmere is soft and warm but wears fast, so it suits jackets and coats better than everyday suits.
- Wool-cashmere blends, commonly 95/5 or 90/10, add softness while keeping most of wool's strength.
- In 2026, 95/5 wool-cashmere suiting sold at retail for about $40 to $290 per meter, so fabric for a suit ran about $130 to $1,000.
- Rest, brush and store cashmere with care: it pills at friction points and moths love it.

Cashmere is the fiber most people think of first when they think of luxury, and a cashmere suit feels exactly as good as you would expect: soft, warm and fluid. It is also the least durable fabric a tailor will usually suggest for a suit. Whether it is worth it depends on how you will wear it. As an occasional winter suit, a sport coat or an overcoat, cashmere is a pleasure. As a suit you wear three days a week, it will disappoint. A wool-cashmere blend sits in between, and for most people it is the smarter buy.

What is cashmere?
Cashmere is the fine, soft undercoat of the cashmere goat. Each spring, as the goats molt, the down is combed or shorn from the animal and then dehaired, a process that removes the coarse outer guard hairs. A goat gives only about 150 g of fine down a year, which is one reason cashmere is expensive. China is the largest producer and Mongolia the second. The name comes from Kashmir, whose fine shawls made the fiber famous in Europe.
In the US, the word cashmere on a label has a legal meaning. The fiber must be the dehaired undercoat of a cashmere goat with an average diameter of no more than 19 microns, and no more than 3 percent of the fibers by weight may average over 30 microns. The best cashmere is finer still, about 14 to 16.5 microns, from long combed fibers.
Cashmere
The fine, dehaired undercoat of the cashmere goat. It is softer and warmer than sheep's wool of the same weight but less resilient, so it pills and wears faster.
Why is cashmere so soft, and why does it wear faster?
Cashmere fibers are very fine and relatively short, with a smooth, soft surface. That is why a cashmere fabric feels so fluid, and a brushed cashmere traps still air, so it is warm for its weight. The same qualities work against it in a suit. Short, very fine fibers have less spring and strength than suiting wool, so the fabric recovers less well from creasing and sags at the elbows and knees. Loose fiber ends also work free where the fabric rubs. That shows as pilling under the arms and along the sleeves, and as thin, shiny patches at the seat, inner thighs and elbows.

Is a cashmere suit worth it?
A pure cashmere suit is worth it if you treat it as an occasional luxury: a winter suit for dinners, holidays and events, rotated with harder-wearing suits. It is not worth it as an everyday work suit, because the trousers will wear out long before the jacket and the whole suit will lose its crispness quickly. The case is much stronger for jackets and coats, which take far less friction than trousers.

What is a wool-cashmere blend?
A wool-cashmere blend mixes fine wool with a share of cashmere. The most common suitings are 95 percent wool with 5 percent cashmere and 90 percent wool with 10 percent cashmere, and some jacket and coat fabrics use more. The wool supplies strength, spring and a cleaner line; the cashmere adds a softer feel, a little extra warmth and often a gentle luster. Many winter flannels use the same idea. One well-known English flannel range, for example, is 90 percent merino lambswool and 10 percent cashmere.
| Cashmere share | How it feels | Durability | Best for |
|---|---|---|---|
| About 5 percent | Slightly softer than pure wool | Close to pure wool | Winter suits worn regularly |
| About 10 to 15 percent | Clearly softer and warmer | Good, with a little extra care | Winter suits worn weekly or less; sport coats |
| About 20 percent or more | Very soft and fluid | Lower; pills and wears sooner | Sport coats and overcoats |
| 100 percent | The softest and warmest | The lowest | Occasional suits, jackets and coats |
These are tendencies. The quality of the wool and cashmere, the weave and the finish matter as much as the percentage.
Where does cashmere work best?
Sport coats
A cashmere or wool-cashmere sport coat is one of the most rewarding uses of the fiber. A jacket takes much less friction than trousers, and a soft, brushed cashmere in herringbone, a check or a solid camel, navy or gray looks rich with flannel trousers. Because the jacket is worn alone, you can enjoy pure cashmere without the problem of fragile matching trousers. See our guide to suit vs blazer vs sport coat.
Overcoats
Overcoats are cashmere's best tailored use. A coat sees little abrasion, and cashmere is warm for its weight, so a cashmere or wool-cashmere coat can be lighter than an all-wool coat and just as warm. Our guide to overcoat styles covers the cuts and lengths.
Winter suits
For suits, a blend is the safer choice. A wool-cashmere flannel or worsted with 5 to 10 percent cashmere, in navy, charcoal or mid-gray, makes a soft, warm winter suit that still copes with regular wear. If you want pure cashmere, keep it for occasions and order a second pair of trousers. Our guide to flannel suits covers the classic cold-weather alternative.
Is cashmere warmer than wool?
Yes, for the same weight. Cashmere's fine, soft fibers trap more still air, especially when the fabric is brushed, so a cashmere jacket feels warmer than a wool jacket of similar weight. That makes cashmere and cashmere blends autumn and winter fabrics. Even a light wool-cashmere is a poor choice for hot weather, where an open worsted, linen or mohair blend will be far more comfortable.
How much does a cashmere suit cost?
Cashmere raises the price mainly through the fabric. In bespoke and made-to-measure, fabric is priced per meter, and a two-piece suit takes about 3.2 to 3.5 meters of standard 150 cm wide fabric. As an example of the spread in 2026, a basic suiting of 95 percent wool and 5 percent cashmere sold at a UK fabric shop for about $40 per meter (about 30 pounds), while a premium Italian wool-cashmere flannel with the same 95/5 mix sold for about $290 per meter (about 220 pounds). That puts the fabric alone for a two-piece at about $130 at the low end and about $1,000 at the high end. Pure cashmere suiting from top mills costs more again.
The fabric is only part of the bill. Labor costs about the same for most fabrics, so the cashmere premium makes the biggest difference at made-to-measure prices and less at the top of bespoke, where labor dominates. For full price ranges by city and tier, see suit prices by city.
How do you care for a cashmere suit?
Caring for cashmere tailoring
- 1
Rest it between wears
Give a cashmere suit or jacket at least a day, ideally two, on a broad wooden hanger. Soft, fine fibers need time to recover their shape.
- 2
Brush gently
Use a soft brush, gentler than you would use on worsted, and brush downward to lift dust without roughing up the surface.
- 3
Remove pills carefully
Pilling is normal at friction points. Lift pills gently with a cashmere comb or a fabric shaver rather than pulling them off by hand.
- 4
Empty the pockets
Phones, keys and wallets stretch soft fabric and speed up wear. Carry them in a bag instead.
- 5
Steam, do not press hard
Steam out creases with a handheld steamer. Hard pressing flattens the soft surface and adds shine.
Tip: If a tailor or cleaner presses it, ask for a light press through a pressing sheet.
- 6
Dry clean rarely
Clean only when the suit is marked or at the end of the season, at a cleaner who handles fine tailoring. Spot clean small marks with a damp sponge.
- 7
Store it against moths
Moth larvae feed on cashmere. Store it clean, in a breathable cotton bag with cedar, and check it during the off-season; see how to store suits long term.
Pure cashmere or a blend: how to choose
Ask yourself and your tailor
- How many days a month will I wear it?
- Is it a suit, a jacket or a coat? Trousers wear out first
- What is the exact cashmere percentage?
- What is the weight, and does it suit the season I want?
- Crush the swatch: does it recover, or keep the crease?
- Rub the swatch: does the surface start to fluff or pill?
- Should I order an extra pair of trousers now?
Cashmere is worth it when you match it to the right garment. Put pure cashmere into a sport coat or an overcoat, choose a wool-cashmere blend for a winter suit, and keep worsted wool for the suits that work hardest. For how cashmere compares with every other suit fiber, see suit fabrics explained, and for everyday habits, how to care for a suit.
Questions people ask
Is a cashmere suit good for everyday wear?
A pure cashmere suit is not a good everyday suit. Cashmere is soft and warm but less resilient than wool, so it pills, shines and wears through at the seat and elbows much sooner. For a suit worn several days a week, choose worsted wool or a wool-cashmere blend with about 5 to 10 percent cashmere.
What is the best wool-cashmere ratio for a suit?
For a suit you will wear regularly, about 5 to 10 percent cashmere is the best balance. It adds a softer feel and a little warmth while keeping most of wool's strength. Higher shares feel softer still but suit sport coats and occasional suits better than hard-working ones.
Does cashmere pill?
Yes, cashmere pills, especially under the arms, on the sleeves and anywhere the fabric rubs. Pilling is normal for such a soft, fine fiber and is not a sign of a fault. Lift pills gently with a cashmere comb or fabric shaver, and rest the garment between wears.
Can you wear a cashmere suit in summer?
A cashmere or wool-cashmere suit is too warm for most summer weather, because cashmere traps warm air and is warm for its weight. It is an autumn and winter fabric. For heat, choose an open worsted, a high-twist wool, linen or a wool and mohair blend.
Why is cashmere so expensive?
Cashmere is expensive because each goat gives only about 150 g of fine down a year, and the coarse guard hairs must be removed before the fiber can be spun. Only a few countries produce most of the supply, led by China and Mongolia. The finest grades, about 14 to 16.5 microns, cost the most.
Is a wool-cashmere blend real cashmere?
A wool-cashmere blend contains real cashmere, but usually as a small share of the fabric, often 5 or 10 percent. It behaves mostly like fine wool, with a softer feel. Under US rules, the label must state the percentage of each fiber, so check it before you pay a cashmere price.
Is a cashmere sport coat worth it?
A cashmere sport coat is one of the best uses of cashmere in tailoring. A jacket takes far less friction than trousers, so it keeps its looks much longer than a cashmere suit. A brushed cashmere jacket in camel, navy, gray or a soft check works well with flannel trousers in autumn and winter.
