How to Wear a Cardigan — Men's Outfit Guide

Key Takeaway: Buy one fine-gauge merino cardigan in navy, $80–$150. Specifics: Uniqlo Extra Fine Merino V-Neck Cardigan ($60), Howlin' by Morrison Loose Tongue ($310), or Drake's Lambswool Cardigan ($395). Skip chunky cable-knit cardigans (look like a grandfather costume), skip zip-up athletic versions (read sporty), and skip anything fully unbuttoned (looks like a bathrobe). Button all but the top button.

The Verdict

Buy one fine-gauge merino button-front cardigan in navy, $60–$310. It replaces a blazer in most smart-casual settings, layers under outerwear in winter, and wears equally well over a crewneck tee (casual) or a white Oxford (business casual).

Three specific buys:
  • Uniqlo Extra Fine Merino V-Neck Cardigan — $60. Best fit-to-price under $100. 100% extra-fine merino, surprisingly clean cut.
  • Drake's Lambswool Cardigan — $395. Heavier gauge, English-made, the one to upgrade to.
  • Howlin' by Morrison Loose Tongue — $310. Shetland wool, traditional Scottish make, distinctive texture.
Buttoning rule: Button all but the top button. Fully open looks like you just got out of bed; fully closed looks rigid. The "all-but-one" middle is the answer.

What Not to Do

Eliminate on sight:

  • Wearing it fully unbuttoned, hanging open. Looks like a robe. Button it.
  • Buttoning every button. Reads stiff and slightly costume. Skip the top one.
  • Chunky shawl-collar "Big Lebowski" cardigans. Highly specific, reads costume on most men under 50.
  • Cable-knit cardigans for office wear. Casual fabric in a smart context = mismatch.
  • Athletic zip-up cardigans with the brand logo on the chest. Reads gym, not wardrobe.
  • Cardigans that hit mid-thigh. Hem belongs at or just below the waistband — anything longer is a robe.
  • "Grandpa" cardigans with elbow patches (when you don't actually need elbow patches). Costume.
  • Acrylic cardigans under $30. Pill within three washes, look flat from purchase.
  • Cardigans with hoods attached. Pick a hoodie or pick a cardigan.
  • Wearing them over a [t-shirt + jeans] in summer. Wrong season — cardigans are fall through early spring.

FAQ

Cardigan or blazer — which is more versatile?

Blazer for business; cardigan for smart casual. A merino cardigan is softer, more relaxed, and easier to pack. A blazer is sharper. Most men own both.

How tight should it fit?

Slim through the body without pulling at the buttons. Shoulder seam at the bone. Sleeves to the wrist bone. Hem at the waistband.

Can I tuck a shirt under a cardigan?

Yes — and it's the cleanest look. Tucked-in OCBD or dress shirt under a buttoned cardigan creates a sharp, defined waistline.

Cashmere worth the upgrade?

Yes, after you've worn a merino daily for a season. Cashmere is softer, warmer per gram, and ages with character. But fragile — pills faster, costs 3–5× more.

How do I store it?

Folded, never hung. Hangers stretch shoulders permanently. Stack with cedar blocks against moths.

Can I wear a cardigan with a suit?

Yes — a fine-gauge merino under a navy suit jacket replaces the dress shirt + tie + waistcoat in a modern, softer way. Italian businessmen do this constantly.

How Do You Care for a Merino Cardigan?

Cardigans live or die by how you wash and store them. A $150 merino cardigan looked-after correctly outlasts three poorly-cared-for ones. The four rules below take 10 minutes to learn and save you the cost of a replacement every winter.

Wash cold, hand-wash or wool cycle. Merino, lambswool, and cashmere all felt and shrink at temperatures above 30°C / 86°F. Use The Laundress Wool & Cashmere Shampoo ($20) or, in a pinch, baby shampoo — both are pH-balanced for protein fibres. Skip regular detergent (Tide, Persil): the enzymes literally digest wool. Lay flat to dry — never hang. Wet wool stretches under its own weight. Roll the cardigan in a clean towel to press water out, then reshape on a dry towel. Drying takes 24–36 hours; never use a dryer (felts the fibres) or a heat source (sets pilling permanently). De-pill every 2–3 wears. All natural-fibre cardigans pill at friction points (under the arms, along the side seams, at the cuffs). A cashmere comb ($12, Laura's Loom or Gleener) pulls the pills off cleanly; a battery-powered fabric shaver (Conair, ~$15) is faster but more aggressive — keep it on the lowest setting and never press down. Fold flat, never hang. Hangers stretch the shoulders into permanent points within weeks. Fold the cardigan in thirds, button the top button so the placket sits flat, and stack on a closet shelf. Add a cedar block ($8) to repel moths — they devour wool and cashmere in storage. For long off-season storage (April–September), seal in a cotton storage bag with two cedar blocks; never plastic, which traps humidity and grows mildew.

Pilling: prevent vs fix

Prevention beats fixing. Pilling is friction-driven, so the worst spots are exactly where you'd expect: under a backpack strap, where a coat lining rubs the sleeves, where your watch hits the cuff. Two habits cut pilling in half: rotate between two cardigans (don't wear the same one daily), and turn the cardigan inside-out before any wash so the friction during the cycle hits the inside, not the front. Already pilled? Brush in one direction with a cashmere comb, then mist lightly with distilled water and let it air-dry — the fibres relax and re-knit slightly. This works once or twice per garment, then you're trimming with a fabric shaver.
