Three years ago I stood under a shop awning in October rain, watching my brand-new wool coat soak through at the shoulders, and I finally understood why every second woman in Copenhagen owns a trench. I bought mine the following spring — second-hand, ankle-length, a size too big on purpose — and it has carried me through three springs and two autumns since. It is the single most-worn thing I own.
What I have learned is that the trench is not really an outfit. It is a frame. Almost anything calm and well-fitting can go underneath it, as long as the shoes have some weight and the coat itself is allowed to move. The ten combinations below are the ones I actually rotate, with the mistakes left in, because my first trench — mid-thigh, snug across the shoulders — taught me more than any style guide ever did.
1. Oversized Trench Coat Over Chunky Ribbed Fisherman Knit
The fisherman knit I reach for first — three winters old and still the warmest thing I own.
This is my cold-morning default: an undyed cream cable-knit over a thin white cotton tee, straight-leg indigo jeans, and the trench left open so the ribbing shows. The knit needs real bulk — a fine sweater disappears under a big coat and the whole thing looks deflated. I tie the coat belt in a flat knot behind my back, which pulls the side panels out of the way and stops the fabric flapping against my legs. My test before buying any chunky knit: it should fill the coat’s shoulders without me tugging it into place. Brown leather Chelsea boots ground it. Honest note: a genuine wool fisherman knit is not cheap, and mine cost more than the coat did. Per wear, though, it is the best money in my wardrobe.
2. Monochrome Athleisure Hoodie and Wide-Leg Denim
Sunday-market layers: the hood over the collar is the whole trick here.
I resisted the hoodie-under-a-trench idea for a year because it sounded like a teenager’s outfit. Then I tried it on a grey Saturday and wore it three weekends running. The rules that make it work: the hoodie must be heavy cotton so the hood holds its shape when you pull it out over the coat collar, and everything stays in one family of greys and washed blues so the sporty pieces do not fight the tailoring. I wear wide-leg light-wash jeans that nearly skim the floor and chunky retro runners. My mistake the first time was a thin, floppy hoodie — the hood collapsed into a sad little roll at my neck. If the hood cannot stand up on its own, skip it and wear a crewneck instead.
3. Crisp Blue Button-Down Shirt and Tailored Trousers
The blue shirt I iron on Sunday night so weekday mornings take four minutes.
This is the combination I wear when the day includes a meeting and I cannot be bothered with a blazer. An oversized sky-blue poplin shirt, top two buttons open, tucked into double-pleated charcoal wool trousers with a slim black belt. The trench goes over the top with only the middle button fastened, so the lapels fall open and the blue shows through. Practical tip I learned the hard way: poplin wrinkles if you look at it, so I steam the shirt and trousers together on Sunday and hang them as a set. Four minutes on a weekday morning, done. Black penny loafers keep the ankle clean. Who should skip it: anyone whose trousers are not truly high-rise — a low waistband under a tucked shirt rides down all day.
4. Fine-Gauge Black Turtleneck and Straight Ecru Jeans
Black, ecru, honey — three colours, nothing else, and it never looks unfinished.
When I want to look deliberate with almost no effort, this is it: a fitted black merino turtleneck tucked into rigid ecru jeans, black belt, black square-toe ankle boots, and the honey-beige trench over everything. The dark top makes a slim column in the middle, so the big pale coat reads as a frame rather than a tent. I push the coat sleeves up to mid-forearm — a small hair elastic hidden under the cuff fold keeps them there all day, a trick a tailor showed me years ago. One caution from experience: ecru denim shows every mark, and mine picked up a coffee splash and a bicycle-chain smear within the first month. I keep a stain pen in the bag now and treat marks the same evening.
5. Striped Breton Knit and Relaxed Vintage-Wash Denim
My ferry-to-the-islands outfit — the stripes do all the talking.
The Breton stripe is the one pattern I never get tired of, probably because it behaves like a neutral. Mine is heavy cotton, navy stripes on off-white, worn with a loose front half-tuck into relaxed vintage-wash jeans and a tan leather belt. The trench — mine is a muted stone colour — stays open so the stripes sit framed between the lapels. White leather sneakers with gum soles, canvas tote, done. The practical detail: buy the knit in the heaviest cotton you can find. The cheap thin versions stretch out at the hem by midday and the stripes go wavy, which ruins the whole crisp effect. I paid a bit more for mine five years ago and it still lies flat. Ferry rides, market mornings, long lunches — this one handles all of them.
6. Tone-on-Tone Beige Knitwear and Fluid Cream Trousers
All beige, all different textures — the outfit that taught me tone is a texture game.
Head-to-toe beige sounds like a risk, and the first time I tried it I looked like a parcel. What fixed it was texture, not colour: a brushed oat cashmere crewneck, fluid cream wool-blend trousers that actually move when I walk, and the crisper cotton of the trench over both. Three beiges, three surfaces, and suddenly it reads as intentional. I roll the coat cuffs up once so the knit cuffs show, and knot the belt loosely off-centre rather than buckling it. Cost honesty: the cashmere was a sale find and the trousers were not cheap, but the sneakers are plain beige suede and the bag is an old cream leather one I already owned. Skip this if your day involves toddlers, dogs, or red wine — it is a clean-hands outfit.
7. Chunky Half-Zip Cardigan and Tailored Cargo Pants
Cycling-day layers: pockets that lie flat, boots that grip, a zip I can work with gloves on.
This is my cycling-and-errands outfit. A heavy charcoal half-zip knit over a white tee — I unzip the collar about four inches and spread the points flat — with tailored wide-leg cargo trousers in slate, and black lug-sole Chelsea boots. The trench is the deep khaki one, worn open, with the sleeve straps fastened snugly so no cold air runs up my arms on the bike. The cargo rule I follow strictly: the pockets must lie completely flat against the leg. The first pair I bought had bellows pockets that ballooned out, and under a long coat I looked like I was smuggling lunch. Tailored cargos exist; they just take one extra shop to find. A small crossbody pouch keeps the practical theme and leaves my hands free.
8. Oversized Denim-on-Denim Canadian Tuxedo Under Trench
Double denim, one wash, broken by the belt — my studio uniform in spring.
Double denim works when the two pieces match properly: same medium wash, shirt tucked into straight-leg jeans, and a wide dark-brown leather belt cutting the blue in half at the waist. Without that belt it genuinely does look like a uniform for a job I do not have. The sand trench goes over the top with the collar turned up at the back, and somehow the coat makes the whole thing look considered rather than lazy. I wear oxblood loafers with white socks, which sounds odd and works every time. Practical note: rigid denim softens, so I buy the jeans snug at the waist — mine stretched a full size in the first month and needed the belt on the last hole. Washed and worn together, the set fades evenly, which keeps it matching for years.
9. Graphic Statement Tee and Slip Skirt Contrasting Lengths
The gig tee from 2009, still earning its place — the boots stop the skirt looking precious.
A slip skirt on its own feels too dressed for my actual life, so I rough it up: a washed-out charcoal band tee, front-tucked into a black bias-cut satin skirt, and the trench over both with the hem falling a few inches above the skirt’s hem. That staggered hemline is the whole point — coat, then satin, then chunky black combat boots. The boots are not optional styling here; delicate shoes make this outfit look like two halves of different evenings. My tee is genuinely old, soft at the collar, and I would not swap it for a new printed one — the fading is what makes it work. Time note: the skirt needs a quick steam before wearing, two minutes, because satin shows every crease from the hanger. Who should skip it: anyone who hates mixing registers on purpose.
10. Longline Quilted Vest Layered Beneath Lightweight Trench
Two thin layers instead of one fat coat — the January trick I wish I had known at thirty.
This is the trick that got me through last January: a slim, collarless quilted vest worn under the trench, over a fine merino sweater and slate wool trousers. Neither layer is warm enough alone in proper cold; together they work like a real winter coat, and I can peel the vest off in a heated shop instead of sweating in a parka. The trench stays unbuttoned so the quilting shows down the centre — it looks deliberate, not like underwear. I fasten the wrist straps tight and add a ribbed beanie and a fringed scarf over the lapels. Cost note: the vest was an inexpensive liner from an outdoor shop, far cheaper than buying a second heavy coat. Skip this if your trench is a slim cut — the vest needs a genuinely oversized coat over it or you will feel stuffed.
What I’d buy first — and what can wait
If you are starting from a mixed wardrobe, spend first on the trench itself: oversized, mid-calf or longer, dropped shoulders, real cotton gabardine. Buy it second-hand if you can — trenches turn up in vintage shops barely worn, because people buy them for a look and never learn to wear them. After that, one pair of rigid straight-leg jeans, one good wool crewneck, and leather boots with some sole. Those four pieces carry most of this page. Everything else — the Breton knit, the graphic tee, the ecru jeans — can come slowly and cheaply as base layers rotate. What can wait: a second trench in another colour. I wanted one for two years. I still own one, and it is enough.
Questions I get asked
How long should a trench coat actually be?
Mid-calf at the shortest, ankle if you are tall enough to carry it. My first trench ended at mid-thigh and it never layered properly — it looked like a jacket that had given up. The long hem is what gives you the movement and the room for chunky knits underneath.
How do I stop an oversized trench looking like I borrowed it?
Leave it open, or fasten only the middle button. Tie the belt in a loose knot behind your back instead of cinching it tight at the waist, and ground the volume with footwear that has weight — lug-sole boots, chunky loafers, retro runners. Thin delicate shoes under a big coat are the one combination that never works for me.
How do I keep the coat looking crisp?
Hang it on a wide wooden hanger, never a wire one, so the shoulders keep their shape. Steam the lapels and hems regularly — creased gabardine makes the whole outfit look tired. If it gets rained on, let it air-dry in a ventilated spot away from direct heat before it goes back in the wardrobe, and refresh the water-repellent spray once a season, especially on the shoulders and cuffs.
Can I really wear a trench in deep winter?
Yes, with the quilted-vest layering from outfit ten, or over your thickest knit with a scarf sealing the neck. What a trench will not do is replace a down coat at minus fifteen. I wear mine from about minus five upward, which in a coastal winter is most days.
How do I store all the knitwear these outfits need?
Folded flat, never hung — hangers stretch wool shoulders and ruin collars within a season. I keep mine in open shelves sorted by colour family, neutrals together, so I can see the whole trench rotation at a glance in the morning.
One honest coat, worn open, over clothes you already like — that is the entire secret, and it took me an expensive soaked wool coat to learn it. If one of these combinations joins your rotation, save it to your trench board on Pinterest for the next grey morning. — Elias
