British knitwear has a heritage that predates most global fashion brands by centuries. John Smedley, founded in Matlock, Derbyshire in 1784, is the oldest manufacturing company in the UK still operating from its original site and producing fine merino wool knitwear using skills passed down through 240 years of continuous production. That longevity reflects something real: British wool knit traditions developed partly in response to genuine need — the UK's damp, cold climate, its coastal exposure, and its long winters created demand for garments built to last across decades rather than seasons. The Fair Isle patterns from Shetland, the Aran stitches from the Irish west coast (adopted into British knitwear tradition), and the ribbed roll-necks of fishing communities are all functional designs that still define British knitwear aesthetics today. For modern British buyers, the knitwear decision comes down to a combination of fibre choice, construction method, and care requirements. Merino wool — fine, soft, and naturally odour-resistant — is the most versatile choice for everyday UK wear, appropriate for work, walking, and weekend use. Lambswool is coarser but warmer and more durable, better suited to outdoor and country use. Cashmere is the softest but also the most fragile and expensive, and the least practical for the muddy walks and damp days that define British outdoor life for most of the year. Shetland wool, with its natural lanolin content, offers natural water resistance that makes it a practical choice for exposed outdoor conditions. Moth damage is a significant concern for British knitwear owners. The clothes moth (Tineola bisselliella) is endemic across the UK and causes substantial annual damage to wool garments in storage. Cedar blocks in drawers, lavender sachets, and sealed storage bags are the standard UK prevention measures — none is completely effective, but together they significantly reduce risk. Any natural-fibre knitwear stored in a wardrobe or chest of drawers in a UK home is at risk without some form of moth deterrent.
What to Look For
- 1Choose your fibre based on how and where you plan to wear the knit. Merino is the best everyday choice — fine enough for office wear, warm enough for a British autumn day, and machine washable in most quality versions. Lambswool is warmer and more durable for outdoor use. Cashmere is luxurious but fragile — reserve it for occasions where you won't be walking through muddy fields or catching public transport.
- 2Check whether the knitwear is hand-wash or machine-washable. Merino wool knits from quality brands like John Smedley and Barbour are often machine-washable on a wool cycle at 30°C with a specialist wool detergent. This is a significant practical advantage in the UK, where rain and mud make frequent washing necessary.
- 3To protect knitwear from UK clothes moths, store off-season knitwear in sealed zip-lock bags or vacuum storage bags rather than open drawers or wardrobes. Cedar balls and lavender sachets are deterrents but are not reliable on their own. Wash knitwear before storing — moth larvae are attracted to the perspiration and food residues in unwashed fibres.
- 4For hand-wash-only knitwear, use a wool-specific detergent (Woolite or Perwoll Wool) and lukewarm water — never hot. Rinse thoroughly, then press excess water out gently without wringing. Dry flat on a towel, reshaping while wet — never hang knits as this stretches the shoulders and distorts the shape permanently.
- 5UK women's knitwear sizing typically uses UK dress sizes (6–22) rather than S/M/L, but fit varies significantly between brands. John Smedley's merino knits are cut slim — consider sizing up if you prefer a relaxed fit or plan to wear underneath a coat. Barbour and FatFace tend to run more generously.
