How to Wear a Men's Suit Properly: The Complete Step-by-Step Guide

Step 1 — How to wear a suit properly: fit is the foundation of everything

Jacket length

Jacket length is highly important. Avoid wearing a suit that looks like you borrowed it from your father or that has been languishing in your wardrobe since your prom night! In short, to wear a jacket with elegance, it should resemble neither a smock nor a crop top. So remember this simple rule: if the bottom of the jacket reaches the center of your hand when your arms are resting along your body, that's ideal!

Sleeve length

The sleeve length of your jacket is another crucial element to consider during your shopping session. It's not only a matter of aesthetics but also of functionality. Think about it: a sleeve that is too long is very impractical when you want to write, eat, or shake hands with people you want to impress. On the other hand, a shorter men's jacket sleeve gives the illusion of a jacket that is too small, and you might not be taken seriously.

In this case, how do you know if the sleeve is the right length? Here again, it's not complicated at all: the ends of the sleeves of what you wear under your jacket (e.g., a sweater or sports shirt) should not protrude too far from the jacket sleeve (one or two centimeters at most) when you are standing with your arms relaxed. The goal is to show just a little to achieve a harmonious, flattering effect.

Shoulder fit

Shoulder fit must be impeccable. Once you are wearing the jacket, look at yourself in a mirror from the front and check what is happening at the shoulders. If they extend out to the sides, somewhat like a football player, this will unbalance your silhouette. Along the same lines, if the shoulder seam is close to your neck, you won't be able to move easily and will look like you are suffocating! Thus, for the most elegant fit, the jacket seam should be at the shoulder edge, exactly at the joint.

The fit (waist suppression)

For a flattering fit, button your jacket buttons (except the bottom one) and observe yourself. Does your torso look like a "block"? If so, the jacket is likely too loose, which is not very graceful! On the contrary, do you look like an hourglass and fear the buttons on your jacket will burst as soon as you eat one or two appetizers? These are unmistakable signs of a poor fit. For an impeccable fit, your jacket should not form any creases when buttoned (look for the unflattering "X" shaped crease) and should slightly accentuate your waist.

Buttoning

Jacket buttoning is not to be taken lightly. Did you know that men's fashion experts have a strict rule about this? Thus, you fasten the top button sometimes, the middle one always, and the bottom one never, as applicable. At Ernest, we have collections of contemporary suits, which is why we don't have three-button jackets.

The right length and trouser break

Trouser length is crucial, because pants that are too short or too long are rarely flattering! As a general rule, the bottom of your trousers should graze the top of your shoe when standing. That said, fashions evolve, and some men intentionally opt for a suit with shorter trousers to highlight trendy shoes or socks. To avoid style mistakes, talk to our experts: they are constantly on the lookout for new trends in the fashion world!

The break, for its part, is the crease that forms when the bottom of the trousers lightly touches the top of your shoe. Again, it's all about balance. For example, too many breaks can certainly "break" your look by giving you an awkward, even careless appearance. On the other hand, a medium or slight break, with a subtle crease, is the current standard.

Seat fit

Seat fit is another essential element. Well-cut trousers that follow your body without clinging are essential for an impeccable appearance. For obvious reasons, your trousers should neither gape nor form inappropriate wrinkles nor be too tight around your hips and seat, whether flat or rounded. The waist circumference should allow you to breathe easily, and nothing should "pull" at the crotch level. In short, comfort and decency are key!

Step 2 — The collar, waistcoat, and gorge: details that change everything

Collar fit

Too many men neglect the fit of their jacket collar. Yet, this mistake can ruin their entire outfit, even if the rest is well put together. Here are the rules to follow:

- There should be no gap between the jacket and the shirt at the nape of the neck, as this means the jacket is too large.

- There should also be no crease at the back, as this indicates the jacket is too small.

- The top of your shirt collar should be evenly visible all around your neck for a neat look.

If you have difficulty evaluating your collar fit, ask a men's fashion "pro" for advice — like our stylists at Ernest!

The waistcoat (three-piece suit)

If you have a three-piece suit with a waistcoat, you must ensure that its size suits your silhouette, at the risk of ruining your ensemble, which would be a shame, especially if you are attending a special event where many photos are taken (e.g., prom, gala, or wedding)! Thus, once fastened (except for the bottom button), your suit waistcoat should not form any creases at the shoulders, nor allow your shirt to show above the belt, nor leave the belt itself visible.

Choose your gorge according to your body shape

The gorge (lapel notch) is an element to consider carefully. There are several cuts of men's jackets that allow you to vary your look or flatter your silhouette. Let's take a closer look at a particularity you might observe when shopping for a suit: the gorge.

HIGH GORGE (NOTCH)	NEUTRAL GORGE (NOTCH)	LOW GORGE (NOTCH)
Shows little of the shirt.	Extends down to the center of the jacket.	"Plunging neckline" type.
Flattering for tall men with a strong build. Ideal if the legs and torso are well proportioned.	Suitable for most men. A must for gentlemen with long legs.	Elongates the torso. Ideal for men with wide hips or rather short legs.

Whatever gorge you desire, know that Ernest's collections (both suit and sport jackets) are designed to flatter a range of body shapes.
Consequently, even if your morphology is not typically associated with a specific type of gorge, you can adjust the suit to create a chic effect with the shirt, tie, and so on. There is practically nothing that daunts our experienced stylists: during your visit, your measurements will be taken to select a suit that will look wonderful on you!

Sleeve style and buttoning

A detail to observe: the number of buttons on the sleeve. The more there are (2, 3, 4), the more sophisticated the style. At Ernest, our jackets typically have four buttons, a guarantee of elegance. The choice of jacket always depends on the occasion: a professional meeting, a chic evening, or a special event?

Step 3 — Shirt, shoes, and accessories

Which shirt to wear with a suit?

Three categories of shirts are suitable with a suit.

- White: a dress white shirt is a sensible choice. A safe and universal bet, it works with any suit.

- Solid: the solid-colored shirt is also an excellent option, provided it harmonizes with the suit's shade.

- Patterned: the subtly patterned shirt, such as micro-stripes or fine checks, is also acceptable.

When buttoning your shirt, remember the "collar rule": there should be a one-finger gap between the neck and the collar. Finally, remember that the shirt must always be tucked into the trousers.

Tie, bow tie, or no tie?

Depending on the desired style, you have different options:

- With a tie: its tip should touch the belt buckle.

- With a bow tie: it is reserved for formal occasions (e.g., gala, wedding).

- Without a tie: this look is acceptable with business casual and smart casual styles. In this case, however, ensure your shirt is properly buttoned.

Shoes: what to wear according to the suit?

The choice of your shoes is important. To do this, consider the type of suit.

- Formal: if your suit is formal, black or navy, Oxford or leather derby shoes are safe bets.

- Business casual: with a business casual suit, loafers or dress derbies are ideal.

- Smart casual: in 2026, this casual suit is worn with Chelsea boots or clean-lined espadrilles.

To remember: the golden rule is to wear shoes and a belt in the same tone.

The pocket square and little "extras"

Accessories add character to any suit.

- Pocket square: giving a touch of personality, it should not be exactly the same fabric as the tie.

- Cufflinks: available in several styles, they are reserved for shirts with double cuffs.

- Watch: this accessory should be quality and understated, in keeping with the formality level of the event.

Stylist tip: avoid overloading the look by focusing on a single strong accessory.

Step 4 — Adapting your suit to the occasion

Certain outfits are reserved for specific occasions. Thus, always be sure to adapt your outfit to the event's dress code and follow our expert advice to know which type of suit to choose.

At the office (classic or casual professional attire)

For daily office work or business meetings, for example, these outfits are appropriate:

- Formal context: dark suit (navy blue or charcoal gray).

- Business casual: sport jacket with chinos or dress trousers, no tie.

For a trendy 2026 style, pair a stretch-cotton shirt with an unstructured blazer.

Note that neutral colors such as beige, anthracite gray, and navy blue are recommended in professional contexts.

Wedding or formal event

A wedding, gala, or another major event on the schedule? Keep these tips in mind:

- Wear a two-piece or three-piece suit according to the dress code.

- Select matching accessories, such as a tie, bow tie, or pocket square.

- Color-wise, navy blue and gray are good choices, as is champagne for summer 2026.

Everyday smart casual (2026 trend)

If you want to sport a trendy and unpretentious style, bet on these few suggestions:

- A sport jacket with straight-leg jeans or chinos.

- The soft tailoring style, with light shoulders and a fluid cut, is a strong 2026 trend.

- A suit without a tie or formal shirt, with an open collar or not.

- Clean-lined espadrilles or Chelsea boots.

Classic mistakes to avoid

This list presents the most frequent errors to avoid when wearing a men's suit:

- A jacket whose shoulders extend beyond or ride up towards the neck always creates an unkempt look.

- The bottom button of the jacket fastened is a fashion faux pas that betrays a lack of knowledge of basic style rules.

- Trousers so long that you get a build-up of fabric on the shoe are rather unsightly.

- A shirt that comes out of the trousers automatically gives a sloppy appearance.

- A tie that is too short or too long is an indication that the man wearing it ignores how to properly tie and wear this accessory, which harms his credibility.

- Sports shoes with a formal suit represent nonsense for anyone wanting to make a good impression.

- Too many accessories (e.g., watch + bracelet + pocket square + lapel pin) create an overloaded effect, the opposite of elegance.

- A poorly maintained suit, unbrushed or wrinkled, is an unforgivable style mistake.
