Is Lambswool Itchy? The Honest Answer (And How to Wear It Beautifully)

By Ella Blake  |  Tellar Fashion Hub  |  Knitwear & Fabric Guides

No — lambswool is not always itchy, and if you've been avoiding it because of a bad experience with a scratchy supermarket jumper years ago, you've been missing out on one of the most wearable, warm and genuinely lovely fibres you can put on your body. Let me explain exactly what lambswool is, when it might irritate, and how to wear it brilliantly this season.

What Actually Is Lambswool?

Lambswool comes from the very first shearing of a young sheep — typically at around six to seven months old. That first fleece is something rather special. Because the fibres have never been cut before, the natural tips are rounded and smooth rather than coarse and blunt. The result? A softer, finer texture that sits far more kindly against the skin than regular wool.

I remember buying a lambswool roll-neck from Boden about five years ago and genuinely wondering if I'd accidentally picked up cashmere — it had that same sort of softness. I'd been a bit of a wool-sceptic before that, but that jumper completely converted me.

So Why Do Some People Find Wool Itchy?

The itchiness most people associate with wool is usually down to the fibre diameter — measured in microns. Anything above around 30 microns can start to feel prickly against sensitive skin. Standard sheep's wool often sits in that zone. Lambswool, however, typically comes in at around 18–25 microns, which is noticeably finer. It's not as ultra-fine as merino (which can go below 18 microns) but it's genuinely soft enough for the majority of people to wear directly next to their skin.

The cases where lambswool can feel irritating:

• Very sensitive skin or a known wool allergy — a small percentage of people react to lanolin, a natural wax in wool fibres, rather than the fibre itself

• Low-quality blends — if it's labelled "lambswool blend" rather than 100% lambswool, cheaper fibres may be mixed in

• Poor washing or over-washing — repeated machine washing (especially on a warm cycle) can felt and roughen the fibres significantly

• Wearing it directly on very bare, dry skin in winter — a fine cotton or silk base layer underneath eliminates most complaints entirely

How Does It Compare to Other Wools?

Think of it as sitting on a spectrum. At the ultra-soft end you've got cashmere and vicuña. Next comes merino, then lambswool, then regular wool, then the scratchy stuff of childhood nightmares. Lambswool hits a genuinely sweet spot — softer and more refined than standard wool, more durable and affordable than cashmere, and with a beautiful natural warmth that synthetic fibres just can't replicate.

For autumn and winter layering, I'd genuinely reach for lambswool over cashmere half the time — it holds its shape better, pills less, and lasts years with the right care.

Where to Buy Brilliant Lambswool — My Brand Picks

High Street & Mid-Market:

• M&S — their Pure Lambswool range is a consistent bestseller for good reason; the fit is reliable and the colour palette is excellent season on season

• White Stuff — beautiful, characterful lambswool knits with a slightly more relaxed, artisan feel; brilliant for weekend dressing

• Fat Face — great for lambswool crew-necks and half-zips; more outdoorsy in spirit but genuinely warm and well-made

• Boden — consistently strong knitwear offering with fun prints and colours alongside classic styles; quality is notably good for the price

• Barbour — their heritage lambswool jumpers are classics for a reason; the cable-knit styles in particular are worth investing in

• Jigsaw — a step up in quality from the high street; their lambswool pieces are cut beautifully and tend to be more elevated in palette

• Mint Velvet — excellent for softer, more feminine lambswool styles; their oversized half-zip and V-neck options are very wearable

• Whistles — reliably chic knitwear with clean, pared-back shapes; their lambswool pieces feel more premium than the price point suggests

How to Style Lambswool This Season

Lambswool's texture means it works best when it's the hero of the outfit rather than a supporting act. Here's how I'd style it:

• The classic pairing: A fine lambswool crew-neck tucked loosely into tailored wide-leg trousers. Effortless, put-together, eternally wearable.

• Weekend layering: An oversized lambswool half-zip over a fine white shirt collar — very clean, very now. Add straight-leg jeans and Chelsea boots.

• Smart-casual: A fitted lambswool V-neck over a crisp shirt with tailored trousers and loafers. Wear it to the office, dinner, or a gallery opening — it works everywhere.

• The throw-on piece: A slouchy lambswool roll-neck with leather-look trousers and block-heel boots. Add a structured bag and you're done.

One styling note — lambswool tends to look better with a little room in it. Don't size down. The slightly relaxed fit is part of the charm, and going too fitted can create unwanted stretch and pilling.

Caring for Lambswool (So It Lasts Forever)

• Hand wash or use a wool cycle at 30°C maximum — cold is even better

• Use a dedicated wool detergent like Woolite or Delicate

• Never wring — press gently to remove water and reshape flat to dry

• Store folded, not hanging — hanging stretches the shoulders over time

• A fabric comb or de-pilling stone used gently every few wears will keep it looking fresh for years
