What To Avoid When Buying Knitwear This Autumn | And What To Opt For Instead

Knitwear is one of those Autumn purchases it’s dangerously easy to get wrong. The shops fill up overnight, the temperature drops, and it’s tempting to grab the first cosy-looking jumper you see. But a good knit is something you’ll wear on repeat for years, so it pays to be a little more considered. After more than twenty years of buying — and mis-buying — knitwear, here’s exactly what I’d avoid this Autumn, and what I’d opt for instead, with a few of my favourite knits styled into outfits along the way.

Don’t Buy the Chunkiest Knit You Can Find

Avoid instinctively reaching for the biggest, chunkiest knit on the rail. Instead, think about what will actually slide under the coats and jackets you already own. I’m all for wrapping up warm, but a giant, cocoon-like jumper you can only wear on its own will do far less for you than a finer one you can layer beneath a trench, a blazer or your favourite coat. Before you buy, picture it under your existing outerwear — if it won’t fit, it’ll spend most of the season stuck in the wardrobe.

Mind the Gauge, Not Just the Warmth

Avoid overlooking the gauge — how fine or heavy the knit is. Opt for a fine-gauge merino or lambswool for the transitional weeks. A finely knitted jumper layers beautifully under shirts and jackets, regulates your temperature far better than a heavy chunky knit, and won’t have you overheating the moment the sun comes out. Save the big, textural knits for the depths of Winter, when you’ll actually want them.

Swerve Acrylic — Hold Out for Natural Fibres

Avoid acrylic jumpers like the plague. Hold out instead for 100% wool, or a good cotton blend when it’s within budget. That on-trend acrylic knit feels like a win in the moment, but a few hours in the stuff — clammy, static, quick to bobble — and you’ll wish you’d waited and invested in better quality. Natural fibres breathe, hold their shape and age far more gracefully, so they almost always work out as the better cost-per-wear, even at a higher price.

Outfit One

Rethink the Roll Neck

If you want something a little more current this season, avoid defaulting to a roll neck. It’s all about the funnel neck instead. It’s more sculptural and modern to look at, and because there’s a bit more room around the throat, it tends to be far comfier to wear too — none of that strangled feeling by mid-afternoon.

Don’t Just Buy Jumpers

Avoid filling your basket with crew-neck jumpers alone. Opt for a mix — a fine cardigan, a knitted vest or tank, a funnel neck — so your knitwear actually works together. A good cardigan especially earns its keep in the transitional weeks, layering over a shirt or dress far more easily than a jumper, and a lightweight knitted vest is a brilliant way to add warmth without bulk.

Get the Proportion Right for Your Shape

Avoid a length or volume that simply swamps you. Opt for a shape you can tuck, half-tuck or layer to keep some definition — a slightly cropped knit over a higher-waisted trouser, or a longer one left out over slim jeans. The fibre and colour matter, but it’s proportion that decides whether a jumper looks considered or shapeless.

Outfit Two

Choose Colours That Flatter Near Your Face

Avoid picking a jumper purely because the colour is having a moment. Opt for a shade that genuinely lifts your complexion, because a knit sits right up by your face where colour matters most. It’s one of those small things that makes a real difference to how polished you look — and, in my experience, becomes even more worth paying attention to as we style ourselves over 40. A trend colour is lovely, but not at the expense of one that leaves you looking washed out.

Shop Your Own Wardrobe First

Avoid buying anything new before you’ve looked at what you’ve already got. Do a quick audit instead: pull out everything you actually wore last Autumn, put it to one side, and take an honest look at the colours you truly reached for. By all means dip a toe into a trending shade — ruby red, I’m looking at you — but if you want a safe bet, let the palette you genuinely wear guide you. It’s the fastest way to avoid another “seemed like a good idea at the time” jumper languishing unworn.

Build a Small Knit Capsule, Not a Pile

Avoid the panic-buy of five jumpers the moment it turns cold. Opt for a considered few in colours and shapes that mix and match with each other and the rest of your wardrobe. A tightly edited handful of knits you genuinely love will always beat a drawer crammed with near-misses — and you’ll get dressed far more easily for it.

Outfit Three

Know Which Fibres Your Skin Can Handle

Avoid assuming all wool is created equal where your skin is concerned. Get to know which fibres you can actually tolerate instead. I have eczema and very sensitive skin, so certain knits are a firm no — I usually can’t wear mohair, yet, curiously, I can from Sézane; 100% lambswool is fine, but yak wool sends my eczema potty. The lesson: always check the label, not just to make sure no acrylic has crept in, but to see exactly which wool you’re buying and whether your skin will thank you for it.

Always Do the Itch Test

Avoid buying a jumper — especially online — without ever feeling it against your skin. Opt for holding it to the inside of your wrist or your neck before you commit; those areas will tell you in seconds whether you’ll be reaching for it or quietly retiring it after one scratchy afternoon. If you’re shopping online, check the returns policy and be ready to send back anything that doesn’t pass.

Check the Quality With Your Hands

Avoid buying purely on how it looks on the hanger. Give it a quick quality check instead. Gently stretch the knit to see if it springs back, feel the weight of it, and look closely at the finish around the cuffs, hem and seams. A well-made jumper feels substantial and evenly knitted; a cheap one feels thin and is far more likely to bobble and lose its shape within weeks. A minute of checking now saves a whole season of disappointment.

Outfit Four

Be Wary of ‘Dry Clean Only’

Avoid “dry clean only” labels on the jumpers you plan to actually live in. Apply a bit of common sense instead. Brands often add “dry clean only” to cover themselves, when in reality most wool jumpers can be gently hand-washed at home. For a special piece, by all means follow the label — but for the everyday knits you’ll reach for constantly, a dry-clean-only tag quickly becomes an expensive faff. Check whether it genuinely needs it before you commit.

Skip the Novelty Knit You’ll Wear Once

Avoid the novelty knit destined for a single outing. Opt for shapes and colours you’ll genuinely reach for again and again. There’s nothing wrong with a bit of fun — a fair-isle, a bold colour — but be honest about whether it really suits your everyday style. The jumpers that earn their keep are usually the quietly versatile ones: a good V-neck, a crew that sits well under a blazer, a colour that works with half your wardrobe.

And Once You’ve Bought Well — Look After It

Finally, protect your investment. Avoid hanging your knits, which stretches them out of shape; fold them instead, give them a rest between wears, and keep a comb or fabric shaver handy to de-pill them. A little care is what turns a good jumper into one you’re still happily reaching for in five years’ time.

Get those basics right and knitwear becomes the easiest, most reliable part of your Autumn wardrobe — and the outfits throughout show you exactly how I’d style mine.
