What’s This About

In this guide, a diamond build is an outline whose middle stands out more distinctly between a comparatively narrower upper and lower torso, and dressing it starts with room through the middle.

This guide sets out practical choices for that outline, such as:

how the diamond description differs from oval and the other five shapes

jackets, lapels and buttoning points to try fastened

colour, pattern and layering, with the effect each is meant to have

trouser rise and waistbands checked standing and seated

outfit ideas by occasion and season

and many more!

Everything here is a suggestion to compare on your own body, not a rule.

Key Points

01Diamond and Oval are The VOU’s working descriptions and they overlap; if both sound like you, use both sets of advice.

02Your natural waist does not have to be your largest measurement. A shirt front and a waistband have to accommodate the fullest part of your abdomen, wherever it sits.

03Shoulder structure, peaked lapels, vertical lines and darker colour at the middle are common suggestions, but none has a guaranteed optical effect.

04Check every jacket and trouser fastened, seated and reaching forward before judging the outline.

In this guide, we use diamond for an outline in which the middle stands out more distinctly between a comparatively narrower upper and lower torso.

That is a description of how the outline reads.

It does not require your natural waist in particular to be your largest measurement.

If you do measure, take the fullest part of your abdomen rather than assuming it sits at your natural waist, because the two are not always the same place, and no cut-off in centimetres turns one outline into another.

That is The VOU’s working description rather than an industry standard.

We use oval for a rounded fuller-middle outline with the fullness spread more generally through the torso, and the two overlap; other guides draw the line elsewhere.

If both sound like you, read the oval guide as well and use whichever advice fits the garment problem in front of you.

There are two broad ways to dress a diamond outline, and both are legitimate:

Rebalancing: give the shoulder line more presence and keep a clean line through the middle, if you want the upper and lower body to read as more even.
Working with the outline: concentrate on comfort and fit through the middle and leave the proportions as they are.

Either way, fit comes first, and the same advice can help you dress for any occasion or season.

If you do not know your body shape yet, our body shape quiz is optional; everything in this guide works without it.

Male Diamond Body Shape Specifics

The table compares the diamond description with the other six names The VOU uses.

Each row describes how the outline reads from the front, not a measurement, and no row is a threshold, because none of these names has an agreed cut-off.

What you are comparing	Diamond	Hourglass	Trapezoid	Triangle (Pear)	Rectangle	Inverted Triangle	Oval
Outline seen from the front	The middle stands out more distinctly between a comparatively narrower upper and lower torso	Shoulders and hips look broadly balanced, with a visibly more defined waist	Shoulders look a little wider than the hips, with a gentle taper	The lower torso and hip outline looks broader than the shoulders	Little visible taper through shoulders, torso and hips	Shoulders and upper torso look noticeably broader than the hips	A rounded fuller middle, with the fullness spread more generally through the torso
Overlaps most with	Oval	Rectangle	Inverted Triangle	Oval and Diamond, if the abdomen is fuller	Hourglass	Trapezoid	Diamond
Fit point to check first	Shirt and jacket fastened over the fullest part of the abdomen	Waist shaping that does not compress	Jacket waist and trouser seat	Seat and thigh room in trousers	How much waist shaping you want	Shirt waist once the chest fits	Waistband comfort and shirt fastening, standing and seated
Optional styling aim	More presence at the shoulder, a clean line through the middle	Follow the waist or play it down	Show as much of the taper as you like	Add presence above the waist	Add shape, or keep the line straight	Soften the contrast, or emphasise it	Room and a continuous line through the middle

Six Outfit Ideas for the Diamond Outline

This guide illustrates the ideas with the garments themselves; named examples are collected in The VOU’s separate celebrity article.

1. A jacket that keeps its shoulder line

A jacket with some structure at the shoulder holds that line through the day, where a soft unstructured one tends to follow whatever is underneath it.

It is often one of the first changes worth trying.

Judge it on yourself: check where the seam lands, whether the cloth rumples above it or dents below it, and whether you can still reach forward.

2. A long, clean lapel line

A lapel that runs long and uninterrupted down the front gives the eye a vertical to follow.

Fastened, the jacket holds that line closed through the middle; open, it reads as two verticals instead.

Both work, and which you prefer is worth settling in front of a mirror.

3. Dark, plain cloth through the middle

Plain dark cloth through the body of a jacket or a shirt keeps the middle quiet if that is what you want, and it is the easiest version of the colour suggestions further down to actually buy.

4. Colour blocking higher up

A lighter panel across the chest and shoulders over a darker body puts the colour interest higher in the outfit.

Compare it with a plain garment to see whether you like the effect.

5. Vertical detailing rather than horizontal

Plackets, darts, seams and fine stripes run up and down.

A contrast waistband or a horizontal panel puts a line across the middle, which is worth choosing deliberately rather than by accident.

6. Restraint with accessories

A dark structured suit worn with very little is simple to put together.

If you would rather add something, a pocket square or a tie puts it near the face rather than at the waist.

Styling Principles for Diamond Body Shape

If you want a more even outline, the principles below are the usual starting points.

The right-hand column is the intended effect, which is worth checking in a mirror rather than taking on trust.

Principle	Application	Intended effect
Shoulder presence	Jackets with some shoulder structure, padding and a little sleeve-head roping	A more defined shoulder line against the middle
Vertical emphasis	Pinstripes, a clean centre front and long lapel lines	A continuous vertical line through the torso
Room through the middle	Jackets and shirts that fasten without pulling over the fullest point	A clean front with no strain lines
Colour placement	Darker colours at the middle, lighter tones or details at the shoulders and chest	Colour interest higher in the outfit
Fabric	Cloth with enough body to hold its shape	Garments that skim rather than cling

Diamond Body Shape: Styling Tips

The tips below follow the rebalancing approach.

If you prefer to work with the outline as it is, keep the fit checks and treat the rest as optional.

Shoulder Structure

Select jackets with some shoulder structure: a pad and a sleeve head set with a little rope give the shoulder line more presence than a soft, unpadded jacket does.

How much is a matter of the jacket and of taste, and structure is not the same as a seam sitting past your own shoulder; check where the seam lands, whether the cloth rumples above it or dents below it, and whether you can still reach forward, as our fitting guide explains.

Peaked lapels are worth trying.

The peaks sit high on the upper chest and point up and out towards the shoulder ends.

Compare them with a notch lapel on yourself; a notch lapel on a jacket that fits you well will usually look better than a peak lapel on one that does not.

Vertical Details

Pinstripes and a clean centre front give the torso a continuous vertical line.

A slightly higher button stance closes the jacket above the fullest point of the middle, which some men find sits better, though a higher stance also shortens the lapel line, so compare both fastened; where the buttoning point sits on you is what to check, rather than a fixed distance.

Plackets, darts and seams on shirts and knitwear add further vertical detail.

Strategic Colour Placement

Darker colours such as navy, charcoal and deep burgundy at the middle, with lighter tones or accent details at the shoulders, put the colour interest higher up.

Subtle colour blocking does the same in one garment, with lighter shades across the chest and shoulders and a darker body.

For shirts and jumpers, details near the collar and shoulders, such as contrasting collars, shoulder panels or upper-chest details, add interest higher up.

Thoughtful Layering

A structured outer layer over a vertically striped shirt is a simple layered combination.

Choose outer layers with some structure at the shoulder and a clean line through the middle, and check that every layer still fastens and moves comfortably over the one beneath.

Trouser Selection

Select trousers with a rise that puts the waistband where it stays comfortable on you.

Rise labels vary between makers, so check where the waistband of the actual pair sits, seated as well as standing.

A waistband below the fullest point of the middle and one above it are both possible; what matters is that it stays put without rolling or pinching.

Braces carry trousers from the shoulders and leave the waistband uncinched, which is worth trying if a belt digs in; trousers cut for braces usually have brace buttons on the waistband, most often inside, and wearing a belt or braces is not by itself a sign of a bad fit.

Straight-leg or slightly tapered styles give a clean line from hip to ankle.

Pleats are worth trying, though what they give you is ease below the waistband, across the hip and thigh, rather than a bigger waistband: the waistband size is what it is, so check that separately by fastening it and sitting down.

A flat-front trouser cut generously does the same job, so compare both rather than assuming pleats are the only route.

Diamond Body Shape Wardrobe Essentials

The table below is a starting point for a wardrobe built around comfort through the middle, with notes on how each category is usually used.

Category	Essentials	Key Features	Styling Notes
Outerwear	Structured blazers, single-breasted coats, tailored jackets	Some shoulder structure, peaked or long notch lapels	Look for presence at the shoulder and a clean line through the middle
Tops	Vertical striped shirts, V-neck jumpers, structured button-downs	Vertical patterns, shoulder details, structured collars	Check that each closes over the middle without pulling
Bottoms	Trousers in a rise that stays comfortable, straight-leg jeans, pleated dress trousers	Comfortable waistband, clean lines, chosen length	Choose styles that skim the seat and thigh without clinging
Accessories	Pocket squares, ties, collar pins	Details near the face	Put points of interest at the chest and collar if you would rather not mark the middle
Footwear	Oxford shoes, Chelsea boots, structured loafers	Clean lines	Match the formality of the outfit

Diamond Body Shape Outfits by Occasion

Three outfit ideas follow, each built on the rebalancing approach.

Casual Outfit Idea

Start with a navy structured blazer with subtle shoulder padding over a vertically striped button-down shirt in light blue and white.

The blazer gives the shoulder line definition, and the stripe adds a vertical line.

Pair with straight-leg dark wash jeans worn where the waistband sits comfortably, standing and seated.

Complete the outfit with brown leather Chelsea boots, and add a finely textured pocket square in a complementary shade for a point of interest at the chest.

Business Outfit Idea

Begin with a navy single-breasted suit jacket featuring structured shoulders, discreet padding and subtle sleeve-head roping, with a crisp white shirt with subtle vertical stripes.

Peaked lapels point towards the shoulder ends and the fine shirt stripe adds a vertical line; both are preferences to compare in a mirror.

Complete the look with flat-front trousers in the same navy, a burgundy silk tie with a subtle pattern and polished black Oxford shoes.

A simple silver tie clip just below the chest line keeps the tie in place.

The shoulder structure and the clean front give this outfit its shape.

Formal Outfit Idea

For an evening event, a black single-breasted dinner jacket with structured shoulders and satin peaked lapels is a classic choice.

Wear it with a white formal shirt with a spread collar and a pleated front, and a black satin bow tie.

Complete it with black formal trousers with a satin stripe down the outer leg, polished black Oxford shoes and a white pocket square in a straight fold.

Traditional evening wear already has strong vertical details, the lapels, the shirt front and the trouser braid, so the main check is that the jacket fastens comfortably over the middle.

Dressing the Diamond Body Shape by Seasons

Diamond Body Shape Outfit for Spring

Begin with a light grey sports jacket with subtle shoulder padding and a faint vertical stripe.

A two-button closure set slightly higher than usual closes the jacket above the fullest point; try it fastened.

Layer over a light blue striped shirt with a medium-spread collar.

A fine stripe reads more quietly than a bold, widely spaced one; which collar suits your face is a face question, covered in our face shapes guide.

Complete with medium-weight navy chinos with a straight leg, hemmed to just meet the shoe, and brown suede derby shoes.

A pocket square in a complementary shade adds interest at chest level.

Diamond Body Shape Outfit for Summer

Select a tan linen-blend blazer with light shoulder structure and a half-canvas construction that holds its shape without adding bulk.

The texture of linen adds interest.

Pair with a white cotton shirt with a button-down collar, shaped to skim the body without clinging to the middle.

Complete with olive green chino shorts cut just above the knee with a flat front, medium brown leather loafers and a woven leather belt in a similar shade.

Diamond Body Shape Outfit for Autumn

Choose a deep olive tweed sports jacket with subtle shoulder structure.

The texture of tweed adds interest.

Layer it over a burgundy merino V-neck jumper and a white Oxford cloth button-down shirt.

The V-neck opens the top of the chest, and the merino adds warmth.

Complete the look with charcoal wool trousers with a straight leg and a gentle break, burgundy leather Chelsea boots and a pocket square that picks up the burgundy and olive.

Diamond Body Shape Outfit for Winter

Choose a navy wool overcoat with structured shoulders, a single-breasted closure and peaked lapels, with a clean line through the body.

Layer it over a charcoal merino turtleneck.

A fine gauge adds warmth without much bulk.

Complete with dark grey flannel trousers in a straight cut, black leather cap-toe boots, a burgundy cashmere scarf and grey leather gloves.

Diamond Body Shape Do’s and Don’ts

Do	Don’t
Invest in tailoring that gets the fit right, particularly at the shoulder and through the middle.	Wear horizontal stripes across the middle by accident; they put the eye there, so choose them deliberately if you want them.
Try jackets and blazers with some shoulder structure if you want more presence at the shoulder.	Buy on the fit name rather than the garment: whatever the label calls the cut, a garment that pulls across the middle will show it, so check it fastened and seated.
Use vertical details like pinstripes and a clean centre front, compared in a mirror.	Skip checking a double-breasted jacket fastened before buying: the overlapping front adds a layer of cloth across the middle, though a soft one with a long lapel line can still work.
Use darker colours at the middle and lighter tones at the shoulders and chest, if you want the colour interest higher up.	Tuck a shirt in without a jacket if you would rather not put a line at the waistband; an untucked shirt of the right length is the alternative.
Choose the rise by where the waistband stays put on you, seated as well as standing.	Put loud pattern, bright colour or busy detail at the middle unless you want the emphasis there.

Dressing a diamond outline well comes down to room through the middle first, then whichever balance you prefer: more shoulder presence and a clean vertical line, or the proportions left as they are.

Experiment with the suggestions above, keep what works on you, and feel free to ignore any of them in favour of your own taste.

All 7 Male Body Shapes and Their Attributes

In the 1940s, the American psychologist William Sheldon popularised a somatotype classification with three types: ectomorph, mesomorph and endomorph.

Somatotypes describe overall build, while styling vocabulary describes the outline and proportions that clothes have to fit.

The VOU uses the following seven body shapes.

Triangle, Inverted Triangle, Rectangle, Trapezoid and Hourglass follow familiar styling usage; Oval and Diamond are described in The VOU’s own words.

Diamond Body Shape, the subject of this guide, also known as Spade, Teardrop or Wedge Reversed. In this guide, the middle stands out more distinctly between a comparatively narrower upper and lower torso.
Hourglass Body Shape, also known as X-Shape, Figure 8 or Wasp. Shoulders and hips look broadly balanced, with a visibly more defined waist between them.
Trapezoid Body Shape, also known as Rhomboid or Regular. Shoulders look a little wider than the hips, with a gentle taper.
Triangle Body Shape, also known as Pear Shape, Bell, A-Shape or Spoon. The lower torso and hip outline looks broader than the shoulders.
Inverted Triangle Body Shape, also known as V-shape or Wedge. The shoulder and upper-torso outline looks noticeably broader than the hips.
Rectangle Body Shape, also known as Straight Shape, Banana, Column or H-Shape. Little visible taper through the shoulders, torso and hips.
Oval Body Shape, also known as Apple Shape, Round, O-Shape or Circular. In this guide, a rounded fuller-middle outline, with the fullness spread fairly generally through the torso.
