A long trench is the coat I'd keep if I could only own one for wet weather. It sheds a shower, covers whatever you're wearing underneath, and makes jeans and a tee look like a decision. The trouble is that most people settle into one combination and wear it on repeat. If you want to refresh your wet-weather rotation, these 30 outfits show what I put under a long trench and, just as important, what I put on my feet when the pavement is slick. Some are casual, some are for the office, a few are for a night out, and every one is built to get through a rainy day intact.
How Long a Long Trench Should Be on Your Height
A long trench usually ends somewhere between just below the knee and mid-calf, and where it lands on you changes the whole outfit. I check it standing in the shoes I'll wear most, then walking, because a coat that looks right in a mirror can catch on the knee with every step.
- Petite: a mid-calf trench can swallow you. I'd look for petite sizing, or a length that ends an inch or two below the knee, and keep the belt tied rather than hanging so the waist stays visible.
- Tall: standard long trenches often land at the knee on taller frames. Tall ranges or a maxi length keep the proportion the designer intended, and check the sleeve covers the wrist bone with your arms forward.
- Curvy: a trench with a back vent and a belt that ties rather than buckles adjusts to your waist. If the coat pulls across the hips when buttoned, size up and take the waist in with the belt.
- Shoulders: the seam should sit at the edge of your shoulder, or slightly beyond on an oversized cut. Anything narrower will pull when you lift a bag.
Sleeves are the easiest alteration on a trench, and hems are fine on most cuts, although a tailor will need to work around any back vent or deep storm flap. I'd rather buy a coat that's a little long and have it shortened than one that's short in the arms.
1. Long trench coat with straight-leg jeans and white sneakers
Beige trench, black crewneck tee, mid-wash straight-leg jeans and white sneakers: it's the combination I'd hand anyone who says they don't know how to wear a trench. The coat's shoulders give the soft denim some structure, and white leather sneakers wipe clean after a puddle in a way canvas never does. Add a compact crossbody and a small umbrella and you're set for coffee, errands or the commute. I keep this one free of logos and big hardware on purpose; the coat is doing enough.
2. Long trench coat with wide-leg trousers and platform loafers
A khaki trench with high-waisted camel wide-leg trousers is my go-to for an office day with rain in the forecast. The fitted white long-sleeve tee keeps the middle narrow so the coat and trousers can both carry volume. Wide-leg hems are the problem in rain, which is why the platform loafer matters: the extra sole height lifts the hem off wet pavement. I'd have these trousers hemmed to the platform, not to a flat shoe. A dark brown leather tote and gold hoops finish it.
3. Long trench coat with leather leggings and knee-high boots
For a sleeker evening version, I put a black leather-look trench over a light cashmere crewneck and glossy black leggings. Matte coat against shiny legging gives an all-black outfit some depth. Flat knee-high boots with rubber soles extend the line and grip wet steps far better than a leather sole. An oxblood or plum top-handle bag adds the only color. Faux leather doesn't breathe much, so this is a cool-evening outfit, not one for a warm, muggy rain.
4. Long trench coat with a knit midi dress and heeled ankle boots
An oatmeal trench worn open over a ribbed black knit midi dress feels like an occasion outfit you can still walk in. Rib knit moves with you through the hips, and a slim belt at the dress waist stops the coat and dress from blurring into one long shape. I'd pick block-heel ankle boots with a water-resistant finish here; a block heel won't sink into soft grass the way a stiletto does. A pendant necklace gives the neckline a focal point. It's comfortable enough that you'll wear it on dry days too.
5. Long trench coat with a turtleneck sweater and barrel-leg jeans
A cropped cream chunky-knit turtleneck, a long camel trench and washed black barrel-leg jeans balance a snug top half against a relaxed bottom. The curve of the jeans picks up the swing of the coat hem. Burgundy flat square-toe ankle boots give it an edge, and a gray-and-white striped wool scarf pulls the palette together. I keep the sweater cropped because a long chunky knit bunches under a trench and you lose the coat's line. It's a good rainy errand-day uniform when damp cold sets in.
6. Long trench coat with a striped poplin shirt and cropped chinos
When the rain is light and the day is packed, I reach for a navy water-repellent trench coat over a striped poplin shirt and khaki cropped chinos. Cropped trousers are a quiet trick for rain: the hem stays above the splash zone, so you don't arrive with wet cuffs. Waterproof slip-on mules with a small platform and a roomy navy backpack handle a full day out. The stripes keep a dark coat from looking heavy, which suits places where the forecast flips every hour.
7. Long trench coat with a midi slip dress and kitten-heel boots
An olive satin slip dress under a long stone trench is one of my favorite contrasts, because the stiff cotton coat and the fluid dress move so differently. It stays daytime-appropriate as long as the coat is on. Pointed kitten-heel ankle boots and a patent belt bag worn high at the waist sharpen the proportions. Keep jewelry to one chain bracelet and small earrings. A practical note: satin water-spots, so button the coat fully if the rain picks up, and choose this for a short walk to brunch rather than a long one.
8. Long black trench coat with all-black layers and combat boots
An all-black rain outfit, built on a matte-black long trench and lace-up combat boots, is the one I recommend to people who hate thinking about splashes. Black hides curb spray, and lug soles grip wet pavement. Underneath, a black merino sweater and slim coated trousers make a narrow column, and the bulk of the boots keeps it from looking severe. Silver hardware on the belt and bag breaks up the dark. Merino is the right knit here because it stays warm even when the cuffs get damp.
9. Long trench coat with a sweater vest and relaxed boyfriend jeans
A beige trench turns more playful over a cream cable-knit sweater vest and a white button-down, with relaxed boyfriend jeans below. I'd keep the raw hem of the jeans just above the shoe so it doesn't wick water up the leg. Platform sneakers keep it street-ready, and a tan felt bucket hat keeps mist off your face without the fuss of an umbrella in a crowd. A leather sling bag worn high across the chest finishes it. It's a Saturday outfit for school runs and market trips.
10. Long trench coat with a pleated midi skirt and sheer socks
A cream double-breasted trench over a charcoal pleated midi skirt is one of the more romantic looks here. A soft pink cashmere sweater tucked in loosely adds warmth, and patent oxfords with sheer black ankle socks bring a preppy note. Patent leather is a smart rain shoe since water beads off it. The long coat matters for the skirt as well: it keeps mist off the pleats, which flatten once they get damp. A taupe mini bag keeps everything neat.
11. Long trench coat with joggers and chunky dad sneakers
A technical khaki trench over a heather-gray hoodie and jogger set is how I'd dress for a travel day in steady drizzle. The long, clean coat makes the soft sporty pieces look deliberate rather than like gym clothes. Chunky white sneakers with reflective details grip wet floors, and the reflective trim is a real help on dark rainy evenings. A sage canvas tote and a baseball cap complete it for airport dashes and long city walks. I'd skip this for anything more formal than travel.
12. Long trench coat with a graphic hoodie and faux-leather pants
A camel trench worn open over a vintage-style graphic hoodie and high-waisted faux-leather pants mixes soft fleece with a slight sheen. Lug-sole Chelsea boots keep you steady. I let the graphic carry the outfit, whether it's a faded band print or a big pop-culture design, and keep everything else plain: a glossy black phone bag and silver hoops. The hood sitting outside the trench collar is fine; it also gives you a backup if the umbrella fails. It's a casual meet-up or weekend outfit.
13. Long olive trench coat with a white tee and ecru denim
An olive long trench over a white crewneck and high-rise ecru jeans feels earthy and light at the same time. Ecru brightens a muted palette and hides grime better than bright white. Tan suede Chelsea boots are the weak point: suede darkens and stains in rain, so I only wear them if they've been treated with a water-repellent spray, and I'd swap in leather on a heavy day. A cognac woven shoulder bag and a silk scarf at the neck add texture. It suits on-and-off spring showers.
14. Long trench coat with a color-blocked sweater and burgundy boots
When gray skies flatten everything, a jewel-toned color-block sweater under a beige trench gives you color right at the collar and cuffs. Cobalt, or a mustard-and-rust pattern, works because the neutral coat frames it. Dark rinse skinny jeans keep the line slim, and burgundy block-heel ankle boots pick up the saturated color. A gold pendant and a soft wool beret in charcoal add a Parisian note. I wear the beret pushed back and to one side so it reads as part of the outfit, not as a costume.
15. Long trench coat with a chambray shirt and white denim
A tan trench over a chambray button-down and white straight-leg jeans feels bright on a dark day. Pale jeans do pick up splashes, so I'd wear them on a drizzly day, not a downpour. Taupe waterproof ballet flats with cushioned insoles keep the look light. Roll the shirt cuffs over the coat sleeves for a relaxed finish. A tan leather tote and tortoiseshell sunglasses round it off, and a clear bubble umbrella keeps the whole outfit visible.
16. Long trench coat with a hooded knit dress and knee-high rain boots
On a blustery day when warmth matters as much as staying dry, I layer a long gray trench over a chunky hooded knit dress in oatmeal or heather gray. The short flared hem of the dress against the long coat gives it shape, and black knee-high rain boots cover the gap between hem and ankle. A thick wool headband and touch-screen gloves handle the cold, and a gray backpack keeps your hands free. Rubber rain boots don't insulate, so on a properly cold day I'd add wool socks.
17. Long trench coat with a satin blouse and tailored cropped pants
If you're presenting to a room and walking there in rain, wear a long navy trench over a champagne satin blouse and tailored black cropped pants. The blouse's sheen does the dressing-up, and the trench's storm flap at the shoulder keeps the satin dry on the commute. I'd always pack a cloth to dab off any drops before you walk in. Black patent block-heel pumps and a structured briefcase bag complete it. Dry, sharp and fully work-appropriate.
18. Long trench coat with a denim-on-denim base and loafers
A light-wash denim shirt tucked into slightly darker straight-leg jeans gives a long beige trench a soft, single-color base to frame. Brown leather loafers with a chain detail and a matching belt tie it together, and a cream blanket scarf at the neck adds warmth and a pattern break. The two washes need to be clearly different or it looks accidental. If you can find a trench with a detachable hood, it's worth having for days when drizzle turns to downpour.
19. Long trench coat with a sweater dress and slouchy knee boots
A charcoal funnel-neck sweater dress looks instantly more put together under a long camel trench. Belting the coat gently at the waist gives the soft dress a shape it doesn't have on its own. Slouchy suede-look knee boots add a relaxed note, and a long pendant draws the eye down the front. I always tuck a pair of folding flats into the tote, a dark brown pebbled leather one here, for when the boots get uncomfortable or soaked. It's a warm, forgiving outfit that never looks sloppy.
20. Long trench coat with a polo neck and linen-blend trousers
A stone trench over a slim black polo neck and soft beige linen-blend trousers mixes a crisp coat with relaxed trousers, and that contrast is what makes it look considered. Dark chocolate woven leather mules keep it airy for early autumn or late spring showers when boots feel too heavy. Honest warning: woven mules let water in, so this is for a light shower and short walks. A leather-strap watch and a small bar stud finish it for a long lunch or a client meeting.
21. Long trench coat with a tie-waist jumpsuit and heeled sandals
On a warm rainy afternoon, I wear a beige trench open over a cotton-blend utility jumpsuit in olive or black. The tie waist gives the jumpsuit structure under the loose coat, and strappy block-heel sandals keep it seasonal; wet feet dry quickly in warm weather, whereas wet socks don't. A waterproof woven clutch, a fine anklet and a wide-brimmed hat to keep drizzle off your face suit a city weekend or travel day when showers come and go.
22. Long trench coat with a cable-knit sweater and coated jeans
When the rain turns cold and biting, a thick ivory cable-knit becomes the center of the outfit under a long camel trench. Check the coat fits over the sweater before you commit: a trench sized for a shirt will strain across the back over chunky cables. High-waisted coated black jeans shrug off light moisture, and waterproof lug-sole Chelsea boots handle slushy corners. A woven infinity scarf and a quilted crossbody keep it cozy without losing the coat's clean shape.
23. Long trench coat with a puff-sleeve blouse and wide-leg culottes
A dark olive trench over a cream puff-sleeve blouse and cropped wide-leg culottes plays with volume in two places. The blouse sleeves need a coat with roomy armholes, or they crush flat the moment you put it on, so I try them together before wearing. Culottes ending just above the ankle avoid splashes. Sculptural heeled mules in black or bone and a round rattan-effect bag give it an artistic finish for a gallery, a creative office or a market stroll.
24. Long trench coat with a henley and cargo pants
A long beige trench gets a practical edge over a slim long-sleeve henley and olive green cargo pants. Cargo pockets echo the trench's military origins, so the two look like they belong together without tipping into costume. I'd choose cargos with flat pockets so they don't bulge under the coat. Black waterproof lug-sole combat boots, a leather watch and one chain necklace finish it. It's the outfit for a day that involves a lot of walking.
25. Long trench coat with a fair isle sweater and cords
For a rainy winter weekend, tuck a festive Fair Isle sweater into high-waisted rust corduroy pants and put a long navy trench on top. The plain coat lets the patterned knit be the focus, and rust cord warms up navy. Corduroy soaks up water quickly, so this is better for sleet and drizzle than for heavy rain. Shearling-lined lace-up duck boots keep feet warm and dry, and a wool beret with leather gloves completes the cold-weather layers.
26. Long trench coat with a collared blouse and a-line mini skirt
A light-gray trench over a pale-blue collared blouse and a charcoal A-line mini is a preppy, youthful look. Sheer black tights connect the mini hem to patent Mary Janes with a chunky heel, which also handle wet ground better than suede. A slim black headband and pearl drops add polish, and a cherry red top-handle bag keeps it from looking too serious. I make sure the trench is longer than the skirt by a good margin so the mini peeks out only when the coat opens. Good for campus, an internship or brunch.
27. Long trench coat with a square-neck bodysuit and high-waist flares
A camel trench open over a black square-neck bodysuit and high-waist flared jeans leans into a 1970s mood. The denim flare echoes the coat's swing and runs one long line from shoulder to floor, which lengthens the frame. Flares do drag in puddles, so I hem them to a platform clog or heeled ankle boot with a water-resistant finish. A black slouchy hobo and oversized tortoiseshell sunglasses carry the vintage note.
28. Long clear PVC trench coat with a brightly colored outfit underneath
A clear PVC trench is the one coat here meant to show off what's under it. Wear it over a bright pink or electric blue set of wide-leg trousers and a fitted top, so the color stays visible and dry. White platform sneakers, a clear tote and silver jewelry keep the futuristic feel. PVC doesn't breathe at all, so you'll warm up fast on a muggy day, and it can crack in real cold. I'd save it for festivals, creative workplaces and short outings.
29. Long trench coat with a quilted vest layered underneath
When a trench alone isn't warm enough but a puffer feels like too much, I add a thin quilted vest in olive or charcoal underneath. It insulates the core without restricting your arms, and the trench keeps the outside sleek. A chunky cream rollneck, straight-leg jeans and waterproof lace-up hiking boots complete it. Size check: the trench needs a little room for this to work, so it's best with a relaxed or one-size-up coat. It's a useful trick for seasons that turn cold in the afternoon.
30. Long trench coat with a matching co-ord and sleek chelsea boots
A knitted co-ord, a slim ribbed top and midi skirt in camel or cream, under a slightly darker long trench creates one unbroken column of color. Black leather Chelsea boots ground it, and a leather belt bag at the natural waist marks your shape without bulk. Glossy gold drops and a structured mini bag finish it. Knit skirts can cling and ride up when damp, so I'd choose a dense, lined rib over a thin jersey knit for this one.
Gabardine Sheds Rain, It Doesn't Stop It
Most classic trenches are made from cotton gabardine, a tightly woven twill that sheds light rain well. It isn't waterproof. In a long downpour, water eventually soaks through the shoulders and the seams, which is why I treat a trench as a coat for showers and drizzle, not for standing at a bus stop in a storm.
What the details are for
The extra flap on the right shoulder and the yoke across the back add a second layer of cloth where rain hits hardest. The wrist straps close the cuffs so water doesn't run up your arms, and the collar can be buttoned up against wind. On a wet day I use all of them; they're the reason the design has lasted.
Caring for it between seasons
- Hang it to dry at room temperature on a wide hanger, never on a radiator, which can shrink cotton and leave a ring.
- Brush mud off once it's dry rather than scrubbing it wet.
- Check the care label before washing; many trenches are dry clean only, and machine washing can strip the water-repellent finish.
- When water stops beading on the surface, a spray-on or wash-in repellent treatment for cotton brings it back. Test it on an inside seam first.
If you need real waterproofing for a wet commute, look for a coat labeled waterproof with taped seams, and accept it'll breathe less than gabardine.
Buy the Shoulders, Then Worry About the Color
If I'm fitting a long trench, I look at the shoulders before anything else, because a sleeve or a hem can be altered and a shoulder can't. Once the coat fits, nearly every outfit here comes down to the same three choices: a base that suits the temperature, a hem that stays out of puddles, and shoes with real grip. Jeans and sneakers or a midi dress and heeled boots both work under it. Get those three right and a rainy day is just another day to get dressed.
