Stand in front of the mirror, let both arms hang loose, then look at exactly three places: the collar, the cuffs and the midsection. If all three are right, you have passed most of the test on how to wear a shirt with a suit. If one is off, the whole outfit, however expensively made, still looks unfinished. The shirt is the layer closest to the body yet it is often chosen last, and that is where many people lose points.
Quick answer
The shirt collar rises about 1–1.5 cm above the jacket collar and hugs the neck. The shirt cuff shows about 1–1.5 cm beyond the jacket sleeve, roughly half a knuckle. The shirt body is trim, not billowing at the waist, and long enough that the tuck does not pull out when you raise your arms. When you wear a full suit, tuck the shirt in neatly.
How to wear a shirt with a suit: 5 checkpoints
| Position | Correct | Common faults |
|---|---|---|
| Collar | About 1–1.5 cm above the jacket collar, snug, with room for one finger | A loose collar that gaps when you wear a tie; a low collar hidden entirely by the jacket collar |
| Cuff | Shows 1–1.5 cm beyond the jacket sleeve | Hidden entirely, or a shirt sleeve so long it covers the back of the hand |
| Shoulder | The shoulder seam sits exactly at the tip of the shoulder bone | The shirt shoulder drops down the arm, making the sleeve bunch under the jacket |
| Body | Trim; you can pinch about 3–4 cm of fabric at each hip | Baggy as a sack, bulging out from the jacket when unbuttoned |
| Length | Covers the seat when tucked in, and does not pull out when you raise your arms | Too short, showing your stomach when you bend over |
The cuff is the detail people think about least, yet it is seen the most. Every time you reach out to shake someone's hand, a measured stretch of shirt cuff is the sign of someone who knows how to dress, and a stretch that is missing or sticks out too far is the sign of the opposite.
Choosing a shirt collar for how you wear your suit
The shirt collar sets the face of the whole outfit. A quick way to choose:
| Collar style | Features | Suits |
|---|---|---|
| Standard (point) collar | Two collar points close together, pointing down | Business suits, small to medium tie knots. The safest style |
| Spread collar | Points set wide apart | Large tie knots (Windsor), formal suits |
| Cutaway | Very wide, almost horizontal | Large tie knots or bow ties, formal suits |
| Button-down | Points buttoned down to the shirt body | Blazers and relaxed styles, not suited to ceremonial suits |
| Mandarin collar | Stands up, no points | No tie, modern suits |
To explore each style in more depth, see types of men's shirt collars. One small tip: the collar must have some stiffness. A soft, flat collar will flop down once you take off your tie.
A white shirt with a suit: which colour goes with which
A white shirt goes with almost any suit, but "white" comes in several tones. Choose a white thick enough not to show your undershirt, and if your skin is dark, a bright white usually suits better than a creamy white.
| Suit colour | Suggested shirt | Note |
|---|---|---|
| Navy | White, light blue, light pink | The classic formula |
| Grey | White, light blue, sky blue | Avoid a grey shirt in the same tone |
| Black | White, light blue, silver-grey | An all-black outfit, shirt included, only suits an evening party |
| Beige, cream | White, light blue, white with a slight cream tint | Avoid a deep yellowish tone |

Do you need to tuck your shirt in with a suit?
Yes, if you are wearing a full suit. When the jacket is open or taken off, shirt tails hanging out look untidy and make the torso look long and the legs short. Tucking in also keeps the belt and waistline neat.
There are two exceptions worth remembering:
- A blazer styled casually with jeans or chinos: the shirt can be worn out if it has a straight, short, neat cut, usually ending level with or slightly below the belt. A long, drooping shirt worn out is not acceptable.
- A shirt designed to be worn untucked: a flat-cut hem of moderate length. A shirt made to be worn tucked in should not be left out; it will look very untidy.
To keep a tuck secure, choose a shirt that is long enough. A short, straight-cut shirt slips out of the trousers easily, while a made-to-measure shirt, with a curved hem that is longer at the back, holds very well.
Can you wear a suit without a shirt?
Yes, with conditions. Under the jacket you can wear a crew-neck T-shirt, a polo or a thin knit, but choose a soft-fabric blazer rather than the jacket of a formal suit. Keep it buttoned when you stand, and do not show a bare chest. For interviews, partner meetings or formal events, a shirt remains the only choice. The article wearing a suit with a T-shirt explains this combination in detail.
6 kinds of shirt to avoid with a suit
- A shirt with a chest pocket. The patch pocket bulges beneath the jacket lapel and spoils the line. Choose a shirt without a pocket.
- A shirt that is too loose. The extra fabric sticks out behind the jacket and bunches at the waist.
- A thin shirt that shows your undershirt. A suit is worn in a formal setting, so the fabric needs to be reasonably thick.
- A bold-striped shirt with a striped tie. Two large patterns fight each other and look busy.
- A soft, flat collar. If the collar does not stand, the tie sags and the jacket collar sits crooked.
- A creased shirt. However expensive, creased means you have not finished dressing. Iron it beforehand, or choose a crease-resistant fabric.
Tips from Mon Amie's master tailors
A shirt and a jacket have to "talk" to each other. When both are cut from the same measurements, the collar, shoulders and sleeves match to the millimetre. If you buy the shirt and the suit from two different places, you may find the jacket collar riding off, or the shirt sleeve sticking out too far.
When buying a shirt, try it on with the jacket, or bring the jacket with you. Don't try a shirt on alone in front of the mirror.
Frequently asked questions
Which suit colour looks good with a men's white shirt?
A white shirt goes well with navy, grey, black and beige suits. For a touch more colour, light blue or light pink are easy to pair. Avoid a shirt in the same colour as the suit.
How much sleeve should show when wearing a shirt under a suit?
About 1–1.5 cm with your arms hanging relaxed. If the jacket sleeve is too long, the shirt cuff is hidden entirely; if it is too short, too much shirt cuff shows. The jacket sleeve can be shortened by adjusting it at the cuff.
Can you wear a suit without a shirt?
Yes, if what is under the jacket is a T-shirt, polo or thin knit, and you choose a soft blazer. For formal events, no.
Do you need to tuck your shirt in with a suit?
With a full suit, tuck in so the tails do not stick out. With a casual blazer, it can be worn out if the shirt is cut short and neat.

Collar, cuffs and fit are three small details, but they make up the feeling of "dressed right", and that is the whole secret of how to wear a shirt with a suit.
