The most common mistake men with a fuller build make when choosing a suit is buying a size up “to give some room”. The familiar result: sagging shoulders, baggy sleeves, horizontal folds across the stomach, and a wearer who looks exactly as much bigger as the surplus fabric. Suits for big men do not need to hide anything; they need to be right: the right shoulder, the right length, the right cut. This article gathers the eight rules we repeat most often in the showroom, taking roughly 85 kg and up as a loose benchmark, just to make it easier to picture.
Quick answer
A suit for a big man should fit through the shoulders, in a dark colour, plain or with a fine vertical stripe, single-breasted with two buttons, with a peak or medium-width notch lapel, a jacket long enough to cover the seat, double vents, a firmly woven wool, and high-rise, straight-leg trousers. Do not buy a size up to hide the stomach, because a loose jacket makes the figure look larger. Made-to-measure settles the problem outright because it is cut to each measurement.
Why does ready-to-wear so often “fail” a fuller figure?
Ready-to-wear is cut to an average build: a moderately full chest, a flat or slightly protruding stomach. When the stomach exceeds that proportion, there are only two options: take a size wide enough for the stomach, so the shoulders and sleeves are surplus, or take the size that fits the shoulders, so the jacket pulls across the stomach. Neither works. That is why the first rule is to choose by the shoulders and then find a way to deal with the rest.
8 rules for choosing a suit for a big man
1. Correct shoulders are the prerequisite
The shoulder seam sits exactly at the tip of the shoulder bone. Excess shoulder makes the jacket sag; a tight shoulder makes it pull and wrinkle around the armhole. The shoulder is almost impossible to alter, so do not compromise on it. The article men's suit size chart by height and weight explains in detail why the shoulder decides the size.
2. Lapels: a peak or medium-width notch, and avoid very wide ones
A peak lapel creates a diagonal line rising toward the shoulder and draws the eye up to the face, so the torso looks slimmer. A regular (notch) lapel of medium width also works. Avoid a very wide lapel, because it makes the chest and stomach look broader, and avoid a very thin one, because it loses balance.
3. Single-breasted, two buttons, fasten the top one
A single-breasted two-button jacket creates a deep V at the chest and lengthens the torso. When standing, fasten only the top button; the bottom one is always left open. Avoid double-breasted jackets with many buttons, or three-button jackets fastened fully closed, because they thicken the body of the jacket and are hard to keep flat.
4. Jacket length: just covering the seat
The hem should cover the seat fully, reaching the line where the seat meets the thigh. A simple test: let your arms hang naturally, and your lightly curled fingers should touch the hem. A jacket that is too short makes the stomach stand out; one that is too long makes the legs look short.
5. Double vents
Double vents let the jacket drape naturally around the hips and not flare open when you sit or put your hands in your trouser pockets. A single centre vent tends to gape into a V when the seat and stomach are full; a jacket with no vent pulls stiff and wrinkles when you sit.
6. A firmly woven wool that holds its shape
A firmly woven wool has drape and holds its cut well, covering natural creases. Choose a moderate weight: too thin and it clings to the body, too thick and the jacket turns stiff and bulky. Avoid surfaces that are too shiny, because they reflect light and make the stomach area stand out.
7. Dark colours, plain or a fine vertical stripe
Navy, charcoal or black make the body look more compact than light colours. A fine vertical stripe creates a slimming, elongating effect. Avoid large checks, big patterns or several contrasting colours across the waist, because the viewer's eye is drawn sideways.
8. High-rise, straight-leg trousers with a single pleat
A higher waistband (at or near the navel) keeps the natural waist instead of sliding below the stomach, and lets the jacket drape better. A straight leg with a single pleat at the front gives extra room at the thigh. Use side adjusters or braces instead of a belt so the trousers are not dragged down. Avoid low-rise trousers and legs that are too tight.
What made-to-measure can do that ready-to-wear struggles to
| Issue | Ready-to-wear | Made-to-measure |
|---|---|---|
| A full stomach but narrower shoulders | You must choose: enough room for the stomach leaves surplus at the shoulders; the right shoulders pull across the stomach | The stomach and shoulders are cut separately to your real measurements |
| Shoulder slope, standing posture | One common cut, with little room for adjustment | Adjusted to your standing posture and shoulder slope |
| High-rise trousers, crotch, pleat | Mass-produced, hard to fit every build | Waist, crotch and thigh width cut for each person |
| Cloth choice, weight, drape | Only a few cloths available | Cloth chosen for your build, climate and colour, to match the weight you want |
| Alteration after fitting | Limited by the existing seams | Baste fitting and adjustment until it fits |
With the bespoke tailoring experience, Mon Amie's artisans take more than 30 measurements, hold a baste fitting and adjust until the garment is finished, so the stomach, shoulders and trousers are each handled specifically for the individual. You can view the price list to choose a suitable cloth line, and read suits for a fuller stomach if the stomach is your main concern.
Tips from Mon Amie's master tailors
- Try the suit on while seated. Sit down and check whether the jacket pulls at the button and whether the trousers strain at the thigh. Standing is not enough.
- If there are horizontal creases around the button, the jacket is tight across the chest or stomach. You need a larger size in the body while keeping the shoulders right, or made-to-measure.
- Choose a waistcoat carefully. A waistcoat only looks good when it fits closely; otherwise it makes the stomach area more prominent. A two-piece suit is usually easier for a fuller figure.
- Wear a tie that is long enough. A short tie draws the eye to the stomach. The tip of the tie should touch the middle of the belt buckle.
- Keep the pocket square neat and the pockets unstuffed. Preserve the jacket's straight lines.
- Do not choose clothes just because they “hide the stomach”. Choose them because they fit the shoulders, keep you upright and are comfortable to wear. Confidence flatters a figure more than any trick.

Frequently asked questions
What size suit should a big man choose?
Choose by the shoulders, not by the stomach. If the stomach still pulls, consider made-to-measure or have a tailor adjust the body of the jacket. Never buy larger to hide it.
What colour suit should a big man choose?
Navy, charcoal and black are three dark colours that slim the figure easily. A fine vertical stripe also works. Avoid large checks, big patterns or glaring bright colours.
Should a big man wear a three-piece suit?
Possibly, but only when the waistcoat is cut to fit closely. A waistcoat that is loose or tight makes the stomach area stand out. If in doubt, a two-piece suit is always the safer choice.
What trousers should go with a suit for a big man?
High-rise, straight-leg, with a single pleat and side adjusters or braces. Avoid low-rise trousers, tight legs, or a belt fastened too tightly below the stomach.
Should a big man choose a looser jacket?
No. A loose jacket makes the shoulders sag, the body wrinkle and the whole figure look larger. Choose a jacket that fits the shoulders, is comfortable enough through the body, long enough to cover the seat, and let the tailor adjust the rest.

A fuller figure is no barrier to a good suit; it only needs a suit cut correctly for you. If you would like to try made-to-measure, you are welcome to book a measuring appointment at one of Mon Amie's 5 showrooms or call the hotline and Zalo on 0888.111.118 for personal advice.
