The Knitwear Buying Guide
There's a moment in every knitwear shop where you pick up a jumper, feel the label between two fingers like you're checking a passport, and think "yep, that'll do." Nobody actually reads it. We read the swing tag with the price on it and the little embroidered logo, and we call it a day.
Which is exactly how you end up with a "luxury" jumper that's 5% cashmere and 95% regret.
Here at Linity Collective we've got a simple house rule: the fabric first, the brand second. A label can't lie to you (there are laws about that), but it can absolutely let you assume things it never actually said. This post is the long version of that idea, the one we keep coming back to across this whole knitwear series, so bookmark it, because every pin in the Linen, Silk & Natural Fabrics board links back here.
1. Read the Label Before the Brand
Luxury wording sells jumpers. Words like "premium," "heritage," and "cashmere-feel" are doing a lot of emotional heavy lifting on a swing tag that costs the brand nothing to print. None of it is regulated the way the actual composition panel is.
So here's the three-step version, the one from the pin that started this whole series:
- Check the percentage. Not the word. The number.
- Read the whole blend. Every fibre listed, not just the one in bold on the product page.
- Match the fibre to the job. Softest isn't always best. Warmest isn't always best either. Best depends on what you're actually going to do while wearing it.
That's it. That's the whole framework, and it works whether you're in a flagship store, scrolling a resale app at midnight, or digging through a charity shop rail with more hope than plan.
2. How to Read a Knitwear Composition Label
The composition label is the one part of the garment that's legally required to tell the truth. Everything else on that swing tag is marketing. This is the fine print, and the fine print is where the actual product lives.
A few things worth knowing:
- Order matters. Fibres are listed by weight, highest first. If polyester is listed before wool, you're not buying a wool jumper with a bit of polyester in it, you're buying the other way round.
- Every fibre earns its spot for a reason. Viscose adds drape and a bit of shine. Polyamide (nylon) adds strength and stretch recovery, so the cuffs don't go baggy by November. Elastane, even at 2%, is doing a specific job.
- A blend isn't automatically a downgrade. A well-considered blend can outperform a "purer" fibre for everyday wear. More on that in a second.
- Care instructions on the same label aren't decoration. They're a direct consequence of what's in the blend and ignoring them is how a good jumper becomes a small, sad jumper.
Read it the way you'd read an ingredients list. It tells you what you're actually getting, not what you're meant to feel about it.
3. What Does "Cashmere Blend" Actually Mean?
"Cashmere blend" is one of the most quietly slippery phrases in knitwear. It's technically accurate at 5% and at 95%, and those are two completely different jumpers wearing the same three words.
Cashmere is expensive to produce, so brands have every incentive to use just enough to earn the word on the label. A little goes a long way for softening a rougher wool, which isn't dishonest, but it is a decision you deserve to know you're making.
Roughly speaking:
- Under 10% cashmere is usually there to soften and add a bit of loft to another fibre, often lambswool or acrylic. Nice touch, not the main event.
- 30 to 50% cashmere starts to genuinely change the hand-feel and warmth of the garment, especially blended with merino or silk.
- 70% and above is where you're paying, correctly, for cashmere as the headline fibre.
None of this means a low-percentage blend is a bad buy. A 10% cashmere jumper at a sensible price for what it is can be a perfectly good coat-layer piece. The problem is only ever paying full cashmere prices for a jumper that's mostly something else.
4. 100% Wool vs Wool Blend
There's a very persuasive assumption floating around that 100% of anything must be the best version of it. Knitwear doesn't really work that way.
100% wool gives you natural temperature regulation, genuine durability, and a jumper that can go years if you look after it. It can also feel if it's not cared for, and depending on the breed of sheep behind it, it can run anywhere from soft to genuinely scratchy.
A wool blend, done well, is a set of trade-offs made on purpose. A touch of nylon adds shape retention, so elbows and cuffs don't bag out. A little viscose or silk adds drape and shine that pure wool doesn't have on its own. A bit of elastane means the jumper moves with you instead of just sitting there being wool at you.
Neither one wins outright. A 100% wool fisherman's jumper is a brilliant, honest garment for the right job. So is a wool-viscose blend that drapes better under a coat and doesn't need hand washing every time. The question was never "which fibre is superior," it's "which one is doing what you actually need it to do."
5. Merino vs Lambswool vs Cashmere
These three get grouped together constantly and treated like interchangeable words for "nice wool," which is doing all three of them a disservice.
| Merino | Lambswool | Cashmere | |
|---|---|---|---|
| Softness | Fine and smooth, low itch factor | Softer than standard wool, not as fine as merino | The benchmark most people are chasing |
| Warmth | Excellent, actively regulates temperature | Good, cosy rather than technical | Very warm for its weight |
| Breathability | Excellent, moisture-wicking | Good | Good, but less technical than merino |
| Durability | Strong, handles regular wear well | Reasonably strong | More delicate, needs gentler handling |
| Best for | Travel, layering, commuting, active days | Everyday jumpers, good value warmth | Occasion pieces, cold still days, indulgence |
If you're the kind of person who's on a train at 7am, in a stuffy office by 9, and outside again by 6, merino is going to outperform cashmere every single time, regardless of what feels more luxurious on the shop floor. Cashmere is a wonderful thing to own. It's just not always the correct answer to "what should I wear to actually live in."
6. Match the Fibre to the Job
This is the bit that turns fibre facts into an actual decision, and it's the part of the framework we probably lean on hardest at Linity Collective.
Ask yourself what the jumper is actually for before you ask what it's made of:
- Daily commuting and office wear → merino or a merino blend. It handles temperature swings between the cold platform and the overheated office better than almost anything else.
- Travel → merino again, for the same reasons, plus it resists odour and creasing far better than most natural fibres.
- Cold, static days (dog walks, spectating, standing around a fire pit pretending you're having fun) → cashmere or a heavier wool blend, warmth over breathability.
- Sensitive skin → finer merino or a cashmere blend, avoid coarser standard wool.
- Low maintenance tolerance → look for a blend with a bit of synthetic fibre for shape retention and machine washability, and don't feel guilty about it.
- Frequent, hard wear → wool blends with added nylon or polyamide, they'll simply outlast a delicate pure fibre.
There's no universally "best" fibre here, only the best fibre for what the day actually looks like for you.
7. How to Judge Whether Premium Knitwear Is Worth
A brand name can absolutely buy trust, marketing, and a nice shop fit-out. It cannot, on its own, buy a better garment. That part still has to be earned by the actual jumper.
Before you let a price tag talk you into anything, check:
- Composition, obviously, using everything above.
- Construction. Are the seams flat and even? Does the ribbing sit properly at the cuffs and hem without already looking stretched?
- Finish. Any loose threads, uneven dye, or wonky pattern matching straight off the shelf is not a good sign.
- Fit and versatility. A beautifully made jumper you'll wear four times a year is still a beautifully made jumper you'll wear four times a year.
- Expected wear and cost-per-wear. A £180 jumper worn weekly for five years is a better investment than a £40 jumper that pills after one wash and gets binned by February.
Brand can absolutely be part of the reason you trust a garment. It should never be the entire reason you're paying more for it. Let the jumper make its own case.
8. Care Requirements Before You Buy
Quick word on this one, because it deserves a mention here even though it deserves its own full article later (coming soon, we promise).
Different fibres come with genuinely different ownership costs. Cashmere generally wants a gentle hand wash or a proper dry clean and a lot of patience. Merino can often go in the machine on a wool cycle without drama. A synthetic-heavy blend might be the most forgiving of the lot.
Before you buy, have an honest conversation with yourself about how much laundry effort you're actually willing to give a jumper. The most beautiful fibre in the world is a bad buy if it ends up permanently at the bottom of the "I'll hand wash this on the weekend" pile, which, statistically, is where good intentions go to die.
9. The Linity Knitwear Buying Checklist
Save this one. Screenshot it, pin it, tattoo it on the inside of your wrist, whatever works.
- ☐ Percentage checked, not just the word on the swing tag
- ☐ Whole blend read, every fibre, not just the headline one
- ☐ Fibre matched to the job it actually needs to do
- ☐ Construction and finish inspected, not assumed
- ☐ Price weighed against expected wear, not against the logo
- ☐ Care requirements considered honestly, before purchase, not after the first wash
The fabric first. The brand second. Every time.
THE FABRIC FIRST. THE BRAND SECOND.
That's the whole Linity philosophy in six words, and it's the thread running through this entire series. Next time you're standing in front of a rail of jumpers, or scrolling one more Pinterest board at 11pm, you'll know exactly what to check and, more importantly, what the brand was hoping you wouldn't.
