Luxury
Cashmere is the fiber that defines luxury in textiles. Harvested from the soft undercoat of cashmere goats primarily raised in Mongolia, China, and parts of Iran and Afghanistan, the fiber is prized for its extraordinary softness, lightweight warmth, and unmistakable hand feel. In suiting, cashmere represents the pinnacle of what natural fibers can offer.
Unlike sheep's wool, cashmere fibers are not shorn but combed from the goats during their spring molting season. Each goat produces only about 150 grams of usable fiber per year, compared to several kilograms of wool from a sheep. This scarcity, combined with the fiber's exceptional qualities, explains why cashmere commands premium prices.
For suiting purposes, cashmere is most commonly encountered in blends (often 10-20% cashmere with worsted wool) or as pure cashmere in sport coats and luxury separates. Pure cashmere suits exist but are rare due to the fiber's limited durability in high-friction garments. Tailors who understand cashmere's strengths and limitations can offer clients an experience that no other fiber can match.
Understanding Cashmere Quality Grades
Cashmere quality is determined by fiber diameter, length, and color. The finest cashmere fibers measure 14-15 microns in diameter, finer even than Super 200s wool. Grade A cashmere, the highest quality, features fibers at least 34mm in length with a diameter under 15.5 microns. Grade B fibers are 16-19 microns, and Grade C can be up to 30 microns. For suiting, Grade A or B cashmere is essential. Longer fibers produce stronger yarns with less pilling, a critical consideration for garments that will see regular wear. Mongolian cashmere is generally considered the finest, though quality varies significantly between producers.
Cashmere in Suiting: Pure vs. Blends
Pure cashmere suiting is a rare luxury. The fabric drapes with an almost impossibly soft hand and provides warmth without weight. However, pure cashmere wrinkles easily, pills with friction, and lacks the structural memory of worsted wool. For this reason, many tailors recommend cashmere-wool blends. A 10-15% cashmere addition to Super 120s or 130s wool adds noticeable softness while preserving the wool's resilience. For sport coats and blazers that see less friction than trousers, higher cashmere percentages (30-50%) work beautifully. Pure cashmere is best reserved for overcoats, where its warmth-to-weight ratio truly shines.
The Cashmere Touch Test
Experienced tailors can identify quality cashmere by touch alone. Genuine fine cashmere feels cool to the initial touch, then warms quickly in the hand. The surface should feel smooth and uniform, without scratchiness or unevenness. Lower-quality cashmere often feels soft initially but has a slight oiliness or irregularity. One professional technique: press the fabric against your cheek. Quality cashmere will feel like a whisper; lesser grades will feel like a conversation. The fiber should spring back when compressed rather than lying flat, indicating good crimp and resilience.
Working with Cashmere: Tailor's Notes
Cashmere demands respectful handling in the workroom. The fabric should be cut with sharp shears or a rotary cutter to avoid pulling fibers. Pin sparingly and use fine pins to prevent permanent holes. Machine stitching should use a small needle (size 9) with reduced presser foot pressure. Hand finishing is strongly preferred for all visible seams. The fabric does not respond well to aggressive pressing; use a cool iron with a press cloth and minimal steam. Many master tailors prefer to shape cashmere through careful steaming rather than pressing, allowing the fiber's natural loft to be preserved.
Pilling: Prevention and Management
Pilling is the most common concern with cashmere garments. Those small balls of fiber that appear on the surface are caused by friction loosening short fibers from the yarn. Higher-quality cashmere with longer fibers pills less, but all cashmere will pill to some degree during the break-in period. The good news is that pilling typically decreases after the first few wearings as the shortest fibers are shed. Advise clients to use a cashmere comb or fabric shaver gently to remove pills, and to avoid carrying bags with straps that cross the body, as this concentrated friction accelerates pilling.

Care Instructions
- Dry clean only, with a specialist cleaner experienced with cashmere
- Allow 48-72 hours between wearings minimum
- Store folded (not hung) for knits; hung for structured jackets

Pro Tip
When offering cashmere blends, explain the blend ratio honestly. Even 5-10% cashmere in a Super 120s base creates a noticeable difference in hand feel. Clients appreciate transparency about what they are getting, and the blend offers far better value than pure cashmere for suiting applications.

Cashmere FAQ
For occasional wear, yes. For daily use, no. Pure cashmere suits wrinkle easily and show friction wear faster than wool. A cashmere-wool blend (10-20% cashmere) gives you the softness upgrade with much better durability. Reserve pure cashmere for sport coats, overcoats, or suits worn for special occasions only.
Genuine cashmere feels cool to the touch initially, then warms. It should be lightweight yet insulating. The fibers are very fine and uniform. A burn test can help: cashmere smells like burned hair and produces a fine ash, unlike synthetic fibers which melt. For fabric purchases, buy from reputable mills with verifiable sourcing. Loro Piana, Colombo, and Todd & Duncan are trusted names.
Pilling is caused by short fibers working loose from the yarn due to friction. It cannot be entirely prevented but can be minimized. Higher-quality cashmere with longer fibers pills less. Pilling typically decreases after the initial break-in period. Use a cashmere comb to gently remove pills, and avoid friction from bags, belts, and rough surfaces.
