What’s This About
Straight-leg, slim and wide-leg trousers can each work for any of the seven body shapes once they fit through the waist, seat and thigh; the shape changes how you might style them.
This guide compares the three cuts and how to wear them, such as:
what each cut does through the leg
how to wear it with a Triangle, Inverted Triangle, Rectangle or Trapezoid outline
how to wear it with an Hourglass, Oval or Diamond outline
rise, break and cloth checks that matter more than the label
and many more!
No cut suits every man automatically, so try each one on with the shoes you will wear.
Key Points
01Fit first: the waistband should fasten and stay put standing and seated, and the seat and thigh should have room to move.
02Rise, leg width and taper labels vary between makers, so check where the trouser actually sits and falls on you.
03A straight leg is the most adaptable starting point; a slim or wide leg is a style choice, not a correction.
04Choose the break by leg width, cloth and shoe, and compare it in a mirror.
Finding trousers that fit well and look right with the rest of your wardrobe takes some trying on, whatever your build.
Three classic cuts cover most needs: the straight leg, the tailored slim fit and the wide leg.
None suits every man automatically, but each can work for any body shape once it fits through the waist, seat and thigh.
The VOU uses seven body shape names.
Triangle, Inverted Triangle, Rectangle, Trapezoid and Hourglass follow familiar styling usage; Oval and Diamond are described in The VOU’s own words.
In this guide, Oval describes a rounded, fuller middle with general fullness through the torso, and Diamond a middle that stands out more distinctly between a comparatively narrower upper and lower torso.
Each describes how the outline reads, not a measurement, and many men sit between two of them.
Below, each cut is explained, followed by styling options for each shape.
The aims mentioned, such as a more even outline, are optional, so keep whatever you like.
Classic Straight-Leg Cut
The straight-leg trouser is one of the most adaptable cuts in menswear.
The leg falls at a broadly even width from the knee down, so it follows the seat and thigh without hugging the calf.
Rise is the distance from the crotch seam to the top of the waistband, and makers label it differently, so a “mid rise” from one brand can sit higher or lower than another’s.
Check where the waistband sits on you, standing and seated, rather than relying on the label or a set measurement.
For triangle body shapes, a straight leg gives the hips, seat and thighs room and falls cleanly, without a taper that can draw attention to the widest point of the leg.
If you want more presence above the waist, Ralph Lauren Purple Label straight-leg trousers with a structured blazer is one combination to try.
With an inverted triangle outline, a straight leg carries some weight through the lower leg, which many men prefer to a very narrow trouser under broad shoulders.
Anderson & Sheppard’s classic cut with a light merino wool jumper is one option.
Trapezoid body shapes often find straight-leg trousers an easy match, since the clean line follows a gently tapering outline.
Brunello Cucinelli’s straight-leg trousers with a fitted Oxford shirt is one combination.
Rectangle body shapes can wear a straight leg as it is, or add waist definition if they want it: a waistband at the natural waist with a tucked shirt and a belt, or a fitted waistcoat, gives the outfit a clearer waist.
Tom Ford’s straight-leg trousers with a well-fitted waistcoat is one example.
For oval body shapes, a straight leg gives comfort through the seat and thighs and keeps a clean line without clinging.
Check the waistband over the fuller middle, standing and seated: some men prefer it above the fullest point of the abdomen, often with braces, others lower.
Kingsman’s classic cut with an unstructured blazer is one option.
For a diamond outline, the same waistband check comes first.
A straight leg with enough room at the seat keeps the trouser hanging in a clean line below a fuller middle, and a jacket long enough to cover the seat continues that line.
Hourglass outlines have a more defined waist between broadly balanced shoulders and hips.
A straight leg gives the hip and thigh room; whether you then follow the waist with a belt and tucked shirt or play it down with a longer, straighter top is your choice.
Drake’s London straight-leg trousers with a fitted dress shirt is one combination.
Tailored Slim-Fit
A tailored slim-fit trouser narrows gradually from the thigh to the hem.
How much it narrows varies between makers, so judge it on you: the trouser should still let you sit, crouch and climb stairs without pulling at the seat or thigh.
Triangle body shapes can wear a slim fit when it is bought for the hips, seat and thighs and only gently tapered; too sharp a taper below a fuller thigh can make the hip look wider.
Tom Ford’s O’Connor trousers with a structured jacket is one combination to try.
For an inverted triangle outline, a slim fit gives a neat line through the leg; if the contrast with broad shoulders looks too strong to you, choose a gentler taper or the straight leg above.
Zegna’s slim-fit trousers with a fine-knit polo is one option.
Trapezoid body shapes often suit a slim fit, since a gentle taper follows a gently tapering outline.
Thom Browne’s narrow, often cropped trousers with a fitted blazer is a more fashion-led version.
Rectangle body shapes can wear a slim fit cleanly; if you want more shape in the outfit, add it at the waist or the shoulder rather than by tightening the leg.
Canali’s slim-fit trousers with a structured sports coat is one combination.
For oval body shapes, a slim fit works best with a moderate taper and enough room through the seat and thigh; check the waistband standing and seated.
Corneliani’s trousers with a moderate taper and an unstructured jacket is one option.
For a diamond outline, a slim fit with a gentle taper can look neat under a jacket that skims the middle; if the taper makes the middle look fuller by contrast, compare it with the straight leg.
Hourglass outlines can wear a slim fit that gives the hip and thigh room without clinging.
Richard James slim-fit trousers with a well-fitted dress shirt is one combination.
Wide-Leg Trousers
Wide-leg trousers carry more cloth through the leg and drape from the seat and thigh to a fuller hem.
They are a deliberate style choice: some men like the relaxed, fluid line, others prefer a closer leg.
The seat and thigh still need to fit; a wide leg that is loose at the seat looks baggy rather than intentional.
A full trouser usually looks best with a cloth that drapes, and with a top that is neater or more fitted, though full volume throughout is also a valid look.
Triangle body shapes can wear a wide leg that falls straight from the hip, so the trouser hangs past the widest point rather than tracing it.
Drake’s wide-leg trousers with a structured blazer is one combination.
With an inverted triangle outline, a wide leg adds some volume below the waist, which some men like as a counterweight to broad shoulders.
Gucci’s wide-leg cut with a fitted dress shirt is one option.
Trapezoid body shapes can wear a wide leg comfortably; keep the seat fitted so the drape starts in the right place.
Ralph Lauren Purple Label wide-leg trousers with a fine merino jumper is one combination.
Rectangle body shapes can use a wide leg to add volume below the waist, with a defined waistband if they want a clearer waist.
Anderson & Sheppard’s classic wide-leg cut with a structured jacket is one option.
For oval body shapes, a wide leg is comfortable and hangs away from the body; make sure it fits through the seat and that the waistband sits where you want it.
Brunello Cucinelli’s wide-leg trousers with an unstructured blazer is one combination.
For a diamond outline, a wide leg that drapes from the seat can give the lower half a little more presence relative to the middle; compare it with a straight leg in the mirror to see which you prefer.
Hourglass outlines get room through the hip and thigh from a wide leg; a fitted waistcoat or tucked shirt follows the waist if you want to show it.
Tom Ford’s wide-leg trousers with a fitted waistcoat is one example.
Conclusion
For most wardrobes, a straight-leg trouser in a year-round wool is the most adaptable starting point; weight labels vary between mills, so choose a cloth that drapes well without feeling heavy.
Whatever your body shape, fit through the waist, seat and thigh comes first.
The break, the fold where the hem meets the shoe, then depends on the leg width, the cloth and the shoe: a narrow leg usually looks neat with little or no break, while a wider leg can take a little more.
Compare it in a mirror with the shoes you will wear.
A tailor can usually adjust the waist, hem and taper of ready-made trousers; how much depends on the cloth available and how the trousers are made.
If you want variety, a straight leg plus a slimmer or wider pair covers most occasions, and charcoal, navy and grey go with most jackets and knitwear.
