First stepA free cotton test trouser, so slim sits close without pulling

Black slim fit pants are the most useful dark trouser a man can own: sharp enough for a dinner, clean enough for the office and easy to dress down with a knit. These are cut to your measurements in a 9 oz Super 130s worsted wool, slim from the thigh to a clean hem, with a flat front, an extended square tab with a button and slanted pockets.

Slim only works when it fits. A slim trouser that is tight across the seat ripples when you stand and strains when you sit, which is the most common complaint about ready-made slim fit trousers. Because ours are cut from your seat, thigh and knee measurements, they sit close without pulling, and your first pair is a free test trouser so you can check that before we cut the wool.

The front is lined to the knee in the satin you choose in the selector, the waistband has a grip inside to keep a shirt tucked and a split at the center back, and the hem is finished by hand. Other cuts and details are available on request: a slim straight leg, a sharper taper, cuffs or an unhemmed leg.

Free Test Trouser

A Free Test Trouser for a Slim Fit

Before we cut your wool, we send you a test trouser in cotton, made to your measurements, free and yours to keep. It is unlined; your satin goes into the final pair.

A slim cut is unforgiving, which is exactly why the test pair matters. Sit in a chair, crouch, and walk up a flight of stairs. If the cloth pulls into horizontal lines across the seat or the thigh, tell us; if the hem bunches over the shoe, tell us how short you want it. We adjust the pattern and cut your black wool to the corrected fit.

How Slim Should Fit

How Slim Fit Pants Should Fit

Men's black slim fit pants with an extended button tab, worn with a white shirt and brown shoes, front view

How should slim fit pants fit? Close, but never tight. The seat should lie smooth with no horizontal lines, the thigh should have enough room to pinch a little cloth on each side, and the leg should narrow from the knee to a hem that just touches the top of your shoe with little or no break. If you can see pockets flaring open or lines radiating from the crotch, the trouser is too tight.

SkinnyTight from hip to ankle; casual only, not a dress cut
Slim, this pairClose through the thigh, narrowing below the knee; sharp and wearable all day
Slim straightClose at the thigh, then straight to the hem; a little more classic
TaperedFuller at the hip, narrowing hard to the ankle
Straight or classicEven width from knee to hem; roomiest

Slim fit pants for men became the default in the last decade, but many are cut on a young, narrow block that does not suit an athletic seat or thigh. Cut from your own measurements, the same slim line works on any build: men slim fit pants should follow the body, not squeeze it. Men’s slim fit slacks cut this way are comfortable enough to wear all day, and slim fit dress pants men wear to work never ride up when they sit.

Black dress pants go by many names: black slim fit dress pants, black slim fit dress trousers, black slim fit slacks. The garment is the same, black dress pants for men with a slim, tailored leg, and it covers more ground than any other trouser. Black slim fit dress pants men wear to the office, black slim fit formal trousers men wear to weddings and black slim fit dress trousers men keep for evenings can all be this one pair.

If black slim trousers men usually buy feel too sharp, ask for a slim straight leg: the slim straight pants men choose for a little more room below the knee. For a classic look, the black straight fit dress trousers men prefer are also available on request. And slim pants for men should never feel like tight pants. Complaints about men tight pants usually trace back to a badly cut seat; men skinny fit pants are a different, casual cut. Slim fit tailored pants and slim fit tailored trousers are what we make, and among men’s wool trousers, slim fit is the shape most clients choose.


What to Wear

What to Wear With Black Slim Fit Trousers

Black is formal by nature, so the way you style black slim fit trousers sets the mood.

White shirtThe sharpest pairing; black shoes for evening, brown shoes for a softer day look, as in our photos
Black shirtA modern evening look; keep the shoes black and the belt slim
Gray or camel knitSmart casual; a crew-neck or rollneck over the black wool
BlazerCharcoal, gray or camel jackets work; avoid a navy so dark it looks like a mismatched black

For smart casual, black slim fit trousers men wear with a knit and loafers look more deliberate than chinos. Black tailored trousers men wear for smart casual dinners need only a crisp shirt and clean leather shoes. Casual slim fit pants in black work well with a knit, and smart casual slim fit pants men wear this way look better in wool than in stretch cotton. Black trousers for men’s smart casual evenings need only a crisp shirt and clean leather shoes; if you prefer a black shirt, charcoal trousers for smart casual are the softer reverse, covered on our charcoal page. For formal days, these are tailored dress pants men can wear as slim fit formal pants for men who need something sharp at events or as slim fit suit pants under a black jacket. Black tailored dress pants men own often get the most wear of any trouser, and black tailored trousers, men’s smart casual staple, sit with every color. For a softer, less stark dark trouser, our charcoal gray dress pants are the alternative: charcoal reads formal without the contrast of black.

The Details

Tab, Split and Grip

The details are what separate a tailored trouser from a ready-made one, and on a slim cut they show.

Extended square tabCloses with a button beyond the fly, so the waistband lies flat under a shirt
After-dinner splitA small split at the center back of the waistband that lets it give when you sit, a traditional tailoring detail
Waistband gripKeeps your shirt tucked through the day
Lined to the kneeSatin in the front of the leg so the wool glides over the knee and hangs cleanly
Hand-stitched hemInvisible from outside, and easy to adjust later

Every seam is cut with generous allowances, so the trousers can be let out or taken in years from now. Tailored pants men buy ready-made rarely have these details. Customization is available on request: write it in the comment box on the measurement form.


The Cloths

Super 130s Worsted, and Tropical Wool Colors

The black in our photos is a 9 oz Super 130s worsted wool: smooth, firm and dense enough to hold a sharp crease and a slim line through a long day. The selector also offers the same cut in Super 140s tropical wool, a lighter, more open cloth for warm weather, in black and the colors below.

Questions & Answers

Questions About Black Slim Fit Pants

Q. How should slim fit pants fit?
A. Close to the body without pulling. Stand in front of a mirror: the seat should be smooth, with no horizontal lines, and the front pockets should lie flat rather than flare open. Sit down: you should not feel the cloth straining across the thigh. The leg should narrow from the knee to a hem that just meets your shoe. If any of those fail, the trouser is too tight, not slim. Black slim dress pants show strain lines more clearly than lighter colors, so it is worth getting right.
Q. What is the difference between slim fit, skinny fit and slim straight?
A. Skinny is tight all the way from hip to ankle and belongs with casual clothes. Slim is close through the thigh and narrows below the knee, which is the cut in our photos and works for dress and smart casual. Slim straight stays close at the thigh but runs straight from the knee down, a slightly more classic line. Tapered starts fuller at the hip and narrows sharply. Write any of these in the comment box and we cut that shape.
Q. Are slim fit pants comfortable for sitting all day?
A. They are when they are cut for you. Most complaints about black slim fit pants men buy ready-made come from a trouser cut on a narrow block that does not match your seat and thigh. Ours are cut from your measurements, have a grip waistband, and a split at the back of the waistband that gives a little when you sit. The free test trouser lets you check comfort before we cut the wool.
Q. What shoes go with black slim fit trousers?
A. Black leather shoes are the formal choice, especially in the evening. Dark brown shoes, as in our photos, soften black for daytime and smart casual; burgundy works too. Loafers and clean leather sneakers suit a smart casual look. With a slim leg, keep the shoe sleek; chunky soles look heavy under a narrow hem.
Q. Can you wear black trousers for smart casual?
A. Yes. Black trousers men wear for smart casual just need softer pieces around them. Pair black slim fit trousers with a gray, camel or navy knit, a crisp white shirt or an open-collar shirt and loafers. The wool and the crease keep them smarter than chinos, while the knit takes the formality down. Avoid a full black outfit in daylight, which can look severe; add one lighter piece.
Q. What is an after-dinner split?
A. It is a small split at the center back of the waistband, a traditional tailoring detail. It lets the waistband give slightly when you sit or after a large meal, which is where the name comes from, and makes the waistband easier to alter later.
Q. Is black or charcoal better for work trousers?
A. Charcoal is easier in daylight and matches more jackets; black is sharper and the natural choice for evening and formal events. If your office is formal or you wear them mostly at night, black is right. If they will be your everyday trouser with mixed jackets, charcoal is more versatile.
Q. How do I care for them?
A. They are machine washable on a cool, gentle cycle; hang them by the hem to dry. Dry cleaning is recommended for a longer life and to keep the black deep. Black wool shows lint, so a quick brush before wearing keeps them sharp.
Q. Is the test trouser free, and how long does it take?
A. Yes, the test trouser is free and yours to keep. It takes 3 to 4 weeks to make and arrives 5 to 10 days after dispatch; once you confirm the fit, your final pair takes 3 to 4 weeks to make and arrives 5 to 10 days after dispatch. Order as early as you can.
