Height 1.75 m, weight 57 kg. Many men with those numbers have slipped on a suit jacket and heard the same verdict: “That jacket hangs on you like it’s on a hanger.” The fault does not lie in the body but in how the jacket was chosen. A suit for skinny men does not need to hide the frame, only to be structured in the right places: full shoulders, a chest that holds its cut, and cloth with enough weight to give the jacket volume.
Quick answer
A slim build calls for light to medium shoulder padding, a medium-width lapel, and mid-weight wool or a textured weave (check, herringbone), and for avoiding a slim fit that is too tight. The jacket must fit the shoulders first, with enough room in the chest to show the body’s lines and a slight nip at the waist. Made-to-measure deals with the difference between chest and waist that a ready-to-wear suit struggles to fit.
Why is it hard for slim men to wear a suit?
Ready-to-wear suits are cut for an average build. Slim men often end up in this situation: choose a jacket that fits the shoulders and the body is loose; choose one that fits the body and the shoulders are tight. The proportions of shoulder, chest and waist in a slim man often depart from that average, so a ready-to-wear jacket easily suffers from two kinds of fault:
- A sagging jacket, with surplus cloth at the chest and back, creating vertical folds that droop down.
- An over-tight jacket, straining across the shoulders and armholes, with horizontal creases around the button that make a slim frame show even more.
So the solution is neither “dress loose to look fuller” nor “dress tight to fit”, but the structure of the jacket.
Five things to get right when wearing a suit as a slim man
1. Shoulder padding: moderate, sitting right on the bone
Shoulder padding gives the shoulder line a square shape and the impression of broader shoulders. Slim men should choose light or medium padding that sits exactly on the shoulder bone. Padding that is too thick makes the shoulders bulge, looks borrowed and is out of proportion with the neck. The shoulder seam must still land exactly at the tip of the shoulder bone, which is a point that cannot be altered.
2. Chest structure: with real shape
A jacket with good chest structure holds its cut and creates a “full” look in the upper body, making a slim man look sturdier. This is one of the advantages of a made-to-measure suit: the structure can be adjusted to each individual build.
3. Lapel width: not too narrow
A narrow lapel makes the body look long and slender, but also thin. A medium to wide lapel (about 8 to 9.5 cm) adds horizontal width and makes the chest look fuller. A peak lapel further emphasises the solidity of the shoulders.
4. Cloth weight and texture
Thin cloth clings to the body and gives away a slim frame. Mid-weight cloth with a raised weave such as herringbone, a small check or birdseye creates volume and depth. Neutral colours that are slightly lighter, such as mid-grey, light navy or light brown, also give a fuller impression than black or very dark colours.
5. Waistcoat and layering
Adding a waistcoat is the simplest way to make the upper body look fuller. A third layer creates thickness without wearing a loose jacket. A three-piece suit in the same cloth, or a waistcoat in a different tone from the jacket, both work well.
Avoid the over-slim-fit mistake
Slim fit is a much-mentioned phrase at the moment, but for slim men it easily becomes a trap. A jacket nipped in too far makes both armholes tight, drags the shoulders and puts horizontal creases across the back. The tighter the cut, the more clearly a slim body shows. The right answer is a moderately fitted cut: enough room for the arms to move, enough chest for the jacket to breathe, and a gentle waist suppression that forms a V-shape.
A simple test: button up and raise both arms to shoulder height. If the jacket hem rides up, the collar lifts away from the back of your neck or the armholes strain, the jacket is too tight. See also the 10 checkpoints in how a suit should fit.
Single-breasted or double-breasted for slim men?
This is a question many men ask when choosing a suit for a slim build. A single-breasted jacket is the safe choice: easy to cut well, suitable for every occasion and creating a slender V-shape through the body. A double-breasted jacket has two symmetrical rows of buttons and adds an extra layer of cloth at the chest and stomach, so for a very slim man it makes the torso look fuller. The condition is that the jacket must fit the shoulders and be the right length: a double-breasted jacket that is too wide or too long will swallow the wearer.
If this is your first suit, start with a single-breasted, two-button jacket in mid-grey or navy with a subtle texture. Once you are comfortable with the cut, try a double-breasted for occasions that call for standing out.
Trousers and accessories for a slim frame
- Trousers. Choose a straight leg with a slight ease, possibly with a single pleat if the waist fits. A leg that is too tight makes the legs look spindly; one that is too wide looks baggy.
- Shirt. A moderately spread collar and a woven fabric with a little weight, such as twill or oxford. A shirt that is too tight makes the neck and body look thin.
- Tie. A medium width of 7 to 8 cm suits a fuller chest. A tie that is too narrow makes the torso look narrow.
- Pocket square. A flat-folded pocket square adds a point of emphasis at the chest.
Tips from Mon Amie's master tailors
What master tailors often tell slim clients is this: re-measure the shoulders more carefully than anywhere else. Slim men tend to measure themselves and choose by chest circumference, when it is the shoulder that decides whether a jacket looks “full”. With made-to-measure, the shoulder is among the more than 30 measurements taken, and at the baste fitting the shoulder line is adjusted close to the bone to suit your exact build, which a ready-to-wear jacket struggles to do.
The second point: do not be afraid to ask the tailor to adjust the structure and the waist suppression specifically for your build. Slim men often need more detail than an average build, and that is exactly where made-to-measure shines.

Frequently asked questions
What matters most when choosing a suit for a slim man?
The shoulder line, the chest structure and the cloth weight. These three points decide whether a jacket has volume. A moderate waist, not over-tight, and straight-leg trousers balance the whole suit.
Should a suit jacket for a slim man have shoulder padding?
Yes, light to medium padding that sits on the shoulder bone. Padding squares the shoulders and makes them look broader, but padding that is too thick looks artificial.
What colour of suit should a slim man choose?
Mid-grey, navy, light brown and colours with a small check texture. Neutral colours slightly lighter than black make the body look fuller than black or very dark colours.
Should a slim man wear a slim-fit suit?
You can, but do not go too tight. Choose a moderately fitted cut with correct shoulders, enough room in the chest and a gentle nip at the waist. A slim fit that is too snug creates strained creases at the armholes and button, making a slim frame show even more.
Should a man under 60 kg get a suit made to measure?
Very much so, because the difference between chest and waist in a slim man is hard to fit with ready-to-wear sizes. Made-to-measure takes more than 30 measurements and adjusts the shoulders, chest structure and waist to each build, so the jacket fits while remaining comfortable.
An invitation from Mon Amie
A slim man does not need to hide his frame, only to wear a suit that is structured correctly. You can meet an artisan through the bespoke tailoring service, choose a mid-weight, textured cloth in the fabric library, or book a measuring appointment to have a baste fitting straight away with a master tailor. If you would like to check your size first, the article “men’s suit size chart by height and weight” in the Handbook category is a good starting point.
