How to Care for a Wool Suit and Overcoat So It Lasts 10 Years
The short answer on how to care for a wool suit: brush it after each wear, air it for 24 hours before it goes back in the wardrobe, never wear it two days running, hang it on a wide wooden hanger, and dry clean it at most twice a year. That routine takes about two minutes a day and is the difference between a suit that dies in three years and one that still looks sharp in ten. This guide covers the full care system for wool suits and overcoats, including what to do when they get wet, how to store them through summer, and the one habit that quietly destroys more good tailoring than anything else.
The Golden Rule: Rest and Rotation
Wool needs 24 to 48 hours of rest between wears, because the fibre is naturally elastic and will recover its shape, shed moisture and release odour on its own if you let it hang. Wool is remarkable stuff. It absorbs up to a third of its weight in moisture vapour, resists wrinkles, and springs back from a day of sitting, but only if it gets downtime.
Never wear the same suit two days in a row. That's the rule. Worn daily without rest, the elbows and knees bag out, the trouser crease collapses and the cloth develops a shine from continuous friction. Two suits worn alternately will outlast three suits worn into the ground one at a time, which is the honest maths behind owning a small rotation from the suits collection rather than one workhorse.
After each wear, empty every pocket (keys and phones stretch pockets and pull the jacket's line off), hang the suit outside the wardrobe, ideally somewhere with airflow, and leave it for a day before putting it away.
Brush After Every Wear, Steam When It Creases
Brushing a wool suit after each wear with a natural-bristle garment brush removes the dust and skin particles that abrade fibres and attract moths, and it's the single highest-value habit in garment care. Thirty seconds, downward strokes, shoulders first, then body, then trousers. Dust is an abrasive; left in the weave, it grinds the fibre every time you move.
For wrinkles, steam, don't iron. A hand steamer (or the suit hung in the bathroom during a hot shower) relaxes wool fibres without crushing them. If you must iron a trouser crease, use a press cloth between iron and fabric and keep the iron on the wool setting, around 150°C, never directly on the cloth or you'll glaze it shiny. The nap of the cloth matters too: brushing and steaming keep the surface alive in a way no dry cleaner ever restores.
How Often Should You Dry Clean a Suit?
Here's the part most men get exactly backwards. Frequent dry cleaning doesn't preserve a suit. It kills it.
A wool suit should be dry cleaned at most twice a year, because the solvents strip the natural lanolin from the fibre and the industrial pressing flattens the canvas and lapel roll. Every trip to the cleaner ages the cloth. The men whose suits look best after a decade are the ones who brush, air and spot-clean, and dry clean only when a suit is properly soiled or at the end of a season before storage.
For small marks, act early: blot (never rub) with a barely damp cloth, or use a drop of gentle detergent on cotton for greasy spots, testing inside a seam first. Sweat and smells come out with airing, not solvents. If you take one thing from this whole guide, take this section.
Hangers, Wardrobes and Moths
A suit jacket belongs on a wooden hanger with shoulder ends 4 to 5cm wide, shaped to mimic your shoulders, because thin wire hangers dent the shoulder padding permanently. Trousers hang best by the cuffs on a clamp hanger, which lets gravity pull the creases straight overnight.
Give each suit breathing room in the wardrobe. Cloth pressed hard against its neighbours can't air, and friction wears the fibres. As for moths: they eat wool, they prefer it unwashed and undisturbed, and they hate cedar and lavender. Cedar blocks or rings near your tailoring (refreshed with a light sanding every few months, since the scent fades) plus regular brushing is real prevention. For long storage, a breathable cotton garment bag beats plastic every time; plastic traps humidity, and humidity is how you get mildew and that thrift-shop smell.
What to Do When Wool Gets Wet
When a wool suit or overcoat gets rained on, shake it out, hang it on a shaped hanger at room temperature away from direct heat, and let it dry slowly for at least 24 hours. Picture the classic case: you're walking to a client dinner, no umbrella, and the sky opens. The coat gets soaked. What you do in the next ten minutes decides whether it matters.
Shake off the surface water. Hang it somewhere with air circulation. And keep it away from the radiator. Direct heat is the enemy: it dries wool too fast, shrinks fibres unevenly and can pucker the front where the canvas and cloth dry at different rates. Wool handles water surprisingly well (sheep stand in rain all their lives), it's heat plus water that does the damage. Once fully dry, brush it and it'll usually look better than before, because rain lifts out dust.
Overcoat-Specific Care
A wool overcoat follows the same rules as a suit, with two additions: comb off pilling where the coat rubs (collar, cuffs, and wherever a bag strap sits), and give it one proper clean before summer storage. Overcoats take more abuse than suits: rain, bag straps, car seats, pub cloakrooms. A cashmere comb or fabric shaver, used gently a couple of times a season, keeps the surface clean of pills.
The end-of-season clean matters more for coats than suits, because moth larvae are drawn to the skin oils and food traces an overcoat collects all winter. Clean it once in spring, store it in a cotton bag with cedar, and it comes out in November ready to go. Between winters, that's the entire cost of ownership. Our overcoats and topcoats and heavier winter coats are built for exactly this kind of long service.
The Care Schedule at a Glance
| When | What to do |
|---|---|
| After every wear | Empty pockets, brush 30 seconds, air on a hanger for 24 hours |
| Between wears | Rest the suit at least a full day; rotate with another suit |
| When creased | Steam, or press with a cloth on the wool setting; never iron bare |
| Monthly | Check collar, cuffs and elbows for wear; comb pilling on coats |
| Twice a year at most | Dry clean, ideally end of season |
| End of season | Clean, then store in a breathable cotton bag with cedar |
Buy Cloth That's Worth Caring For
Care extends life, but the starting material sets the ceiling. A mid-weight wool between roughly 240 and 280 g/m² wears more seasons of the year and recovers better from daily use than a featherweight Super 150s, which trades durability for silkiness. Super 100s to 120s cloth is the sweet spot for a working wardrobe: fine enough to drape well, robust enough to survive a commute. Fit matters to longevity too, since cloth under constant strain wears out at the stress points first; if your jackets always pull in the same places, read our guide to how a suit should fit before blaming the fabric.

Frequently Asked Questions
How often should you dry clean a wool suit?
At most twice a year, and once is fine for a suit in normal rotation. Solvents and hard pressing age cloth faster than wearing it does. Brush and air the suit routinely, spot-clean marks, and save the cleaner for genuine soiling.
Can you put a wool suit in the washing machine?
No. Machine washing shrinks the wool and wrecks the canvas, padding and structure inside the jacket, and no amount of pressing brings that back. Wool trousers marked machine-washable are the rare exception; check the label.
How do you get wrinkles out of a wool suit without ironing?
Steam it. Use a hand steamer, or hang the suit in the bathroom during a hot shower for ten minutes, then let it dry before wearing. Wool's natural elasticity releases most creases within a day of hanging anyway.
How do you store a wool suit long term?
Clean it first, hang it on a wide wooden hanger inside a breathable cotton garment bag, add cedar, and keep it somewhere cool and dry. Never store wool in plastic, and never store it dirty; that's an invitation to moths.
How do you stop moths eating suits?
Brush suits regularly, clean them before storage, use cedar blocks or lavender sachets, and disturb the wardrobe often; moths favour garments left untouched in the dark. Refresh cedar by sanding it lightly every few months.
Should you hang a wet wool coat near a radiator?
No. Direct heat dries wool unevenly, shrinking fibres and puckering the front of the coat. Shake the water off and dry it slowly at room temperature on a shaped hanger; give it a full 24 hours.
How long should a good wool suit last?
Ten years or more in a rotation with proper care, assuming a mid-weight cloth and a fit that isn't straining at the seams. Daily solo use with frequent dry cleaning can finish the same suit in two or three.
Two minutes of brushing, a day of rest and a firm hand with the dry cleaner. That's the whole secret. Buy well from the suits collection, care for it like this, and the cost-per-wear maths gets very kind by year ten.
