Cashmere Buying Guides
Whether you are buying your first cashmere sweater or adding to an existing collection, these guides will help you make informed decisions.
How to Evaluate Cashmere Quality
Not all cashmere is equal. The quality of a cashmere sweater depends on several factors, and understanding them helps you tell the difference between a genuine value and an overpriced disappointment.
Fiber Diameter
The finest cashmere fibers measure between 14 and 15.5 microns in diameter. For context, a human hair is about 75 microns. The finer the fiber, the softer and more luxurious the finished fabric feels. Budget cashmere often uses fibers in the 19-micron range — still technically cashmere, but noticeably less soft.
Fiber Length
Longer fibers (34mm or more) produce a smoother yarn that pills less over time. Short fibers create a fuzzier yarn that pills quickly, even in new garments. This is one of the biggest differences between premium and budget cashmere, and it is not something you can easily see in a product listing.
Ply Count
Ply refers to the number of yarn strands twisted together to create the knitting yarn. Single-ply cashmere is lightweight but less durable. 2-ply is the standard for most quality sweaters — warm enough for most climates and durable enough for regular wear. 3-ply and 4-ply cashmere creates a denser, warmer garment suited to colder environments.
Knit Gauge
A tighter knit gauge means more stitches per inch, creating a denser fabric that retains its shape better, pills less, and lasts longer. Hold a cashmere sweater up to light — if you can see through it easily, the gauge is loose and the sweater is unlikely to hold up well over time.
How to Care for Cashmere
Proper care dramatically extends the life of a cashmere sweater. Most cashmere damage comes from improper washing and storage, not from wearing.
Washing
Hand washing is ideal. Use cool water (never hot) and a gentle detergent formulated for wool or cashmere. Submerge the sweater, gently press it through the water — do not wring, twist, or rub. Rinse thoroughly in clean cool water.
Machine washing is possible on a gentle or wool cycle in a mesh laundry bag. Use cold water and a wool-safe detergent. Never use the regular cycle or warm water.
Drying
Never hang cashmere to dry — the weight of the water will stretch it permanently. Lay it flat on a clean towel, reshape it gently, and allow it to air dry away from direct heat or sunlight.
Storage
Store cashmere folded, never on hangers. Use cedar blocks or lavender sachets to deter moths. Give sweaters a day of rest between wears to allow the fibers to recover their shape.
Pilling
Some pilling is normal, especially in the first few wears. Use a cashmere comb or fabric shaver to gently remove pills. Higher-quality cashmere with longer fibers will pill less over time, while budget cashmere may pill continuously.
What to Spend
Cashmere sweaters range from under $50 to over $1,000. Here is a rough guide to what different price ranges typically offer:
Under $80
At this price, expect shorter fibers, looser knit gauges, and thinner construction. These sweaters may feel soft initially but tend to pill quickly and lose their shape within a season or two. They can work as occasional pieces but are unlikely to become long-term wardrobe staples.
$80 to $200
This range offers the best value for most buyers. Many reputable brands produce well-constructed 2-ply sweaters with good fiber quality at this price point. Expect solid construction, reasonable durability, and a soft hand feel that improves with care.
$200 to $500
Premium cashmere from established luxury brands and specialty knitwear houses. Expect Grade A fibers, tight gauge construction, fully fashioned shaping, and the kind of quality that ages gracefully over many years.
$500 and Above
Ultra-premium and designer cashmere. At this level, you are paying for the absolute finest fibers, exceptional construction, and often a brand name. The quality difference between a $300 sweater and a $700 sweater is smaller than the difference between $100 and $300.
