Three-piece suits are defined by the standard suit jacket and pants, accompanied by a matching vest.

And they’re back in the fashion scene in a tremendous way.

Rather than go for the standard suit that you have always been seen wearing at any event, why not spice up your looks? You can look sharper on that next formal occasion that you are planning to attend.

Three-piece suits complement individuals who are stylish and adventurous with their fashion statement. With different styles and shapes to choose from, finding the one that will perfectly represent your personality will not be difficult at all.

Advantages of Three-Piece Suits

There are many good reasons to wear a three-piece suit. They offer that great, classic look and are always on-trend. Plus, a good three-piece makes a man feel good about himself.

Any guy can slip into a two-piece suit. But adding that third component, the vest (aka waistcoat), somehow makes the perfect finish to an elegant and stylish look. That is if you get the fit and the color just right.

When worn over a dress shirt, the vest becomes an integral part of the trio. And the popular misconception that adding a vest makes you look fat is simply not true. A vest holds everything in place.

It adds structure to your outfit. Nobody can deny that a three-piece suit creates a more ‘put together’ look than a regular two-piece.

Even with your jacket buttons undone, a vest will give you a neat and finished look. The result is a very appealing look indeed.

Another big advantage is that owning a few three-piece suits gives you a lot of dressing options.

You can opt to wear the vest on its own with an open neck long-sleeved shirt and well-fitted jeans. Or you can mix the waistcoat with the jacket and pants from another coordinating suit.

Of course, if you want to be a little less formal, you can leave out the waistcoat altogether and simply wear the suit as a two-piece.

Double-Breasted vs. Single-Breasted Three-Piece Suits

You can choose whether to wear either a single or a double-breasted jacket at any event where a suit is called. But please, only wear a double-breasted jacket as part of a suit, and never as a blazer.

Double-breasted is more formal than a straightforward single-breasted jacket and should always be worn with the proper trousers. Plus, they can’t be dressed down as a single-breasted jacket can.

Single vs. double breasted suit

On the other hand, a single-breasted jacket can be worn with casual pants, such as fitted jeans or chinos, with or without the vest.

Also, single-breasted three-piece suits are worn around 90% of the time and are more widely available. Singles can come with anywhere from one to five buttons.

A lot of younger men are unfamiliar with double-breasted three-piece suits because they can be difficult to find.

Double-breasted suits have an extra fold of fabric across the front, and they also have a second row of buttons. They will usually have a total of four or six buttons.

Here’s an extra tip. Make sure the buttons are in a Y-shape instead of a V. This is considered to be much more stylish, and it will fit better, too.

If you are going to wear a double-breasted suit, your jacket must be a perfect fit. They are not as forgiving as a single-breasted, and the buttons need to come together.

Also, make sure that everything lies flat, with absolutely no puckering.

How to Fit a Three-Piece Suit

Before we decide on your suit’s color, it’s essentially important to match your suit’s fit. The same basic suit rules apply, with a few additions for the vest. Let’s quickly cover them:


Let’s begin with the vest. This may appear straightforward, but it can be quite tricky to find the right fit. Remember you won’t always be wearing your jacket, so the vest has to look good over your shirt too.

There are distinct pointers that can help you find the perfect vest size.

How should a suit vest fit

The front hem, for example, should be long enough to conceal the pants’ waistband.

When the jacket is fastened, an inch or so of the vest’s top part must remain visible. Also, the V of the waistcoat should not obscure the edges of your shirt collar.

Lastly, you want your vest to be narrow at the waist. The sides, however, are just right when they fall straight down.

Don’t forget, the bottom button of your vest should be left unbuttoned.


To get the right fit for your jacket, first, make sure the shoulder pads end where your shoulders do. Nothing looks phonier than shoulder pads that extend too far.

Next, look at the buttons. If there are two, the top one shouldn’t be lower than your navel. If you have three, then the same applies to the middle button. Never fasten the bottom button.

To check the jacket length, stand with your arms at your sides. Your hands need to be where the hem of the jacket ends. The sleeves should reach down to where your thumb and wrist join.

The jacket length

As a final check, the cuff of your shirtsleeve should stick out of your jacket by about half an inch.


The best fit for the trousers of a three-piece suit is high on the natural waist. That said, younger men might prefer a slimmer fit with a lower waist.

The butt wrinkle

It’s best not to wear a belt with a three-piece as it can cause the vest to bulge. Use suspenders instead, or if you can, nothing at all.

Trouser length is very much a matter of personal preference. Shorter guys might prefer the pants’ hem to barely brush the top of their shoes. Taller men often go for the full break. Both are allowed.

Three-Piece Suits Color Combinations

Starting from the bottom up, your shoes should match your three-piece suit’s tone. Brown shoes go nicely with blue or navy.

We always advise black shoes with a black suit, but black shoes work well with navy or charcoal suits, too.

Moving up: for a more formal look, the jacket, vest, and trousers should all be the same color. But wear a coordinating or contrasting vest for a less formal look.

Navy blue, or even a lighter blue, fits right in at weddings. You don’t want to wear anything too dark or somber.

Regarding shirts: white shirts are a staple and go with most suits. They give a crisp, clean look. You can wear almost any color tie with them too.

Pale blue is also a good shade for a dress shirt and provides a classic alternative to white. Pale blue goes with most people’s skin tone and hair color. Add a navy tie with grey or navy suits.

We encourage you to experiment with different color and pattern combinations. The main thing is to avoid the trendsetting look by mix-and-match too many colors.

When to Wear a Three-Piece Suit

A three-piece suit isn’t something you’re going to put on every day just to go to the mall.

Three-piece suits are effortlessly contemporary and stylish and are often preferred at business, weddings, and many other events. As a matter of fact, it’s the best choice by far for any formal occasion.

The modern designs may also be worn on casual nights. It will enable you to stand out from the rest of the crowd at any social event with your mystifying look.

Again, three-piece suits are the perfect choice for your wedding attire. That’s because it perfectly matches with all suit accessories, including suspenders. It’s a celebration, after all, and nobody is going to laugh if you dress up.

If you have an office job, chances are a three-piece suit won’t look too over-the-top. Stay away from bold colors and non-standard accessories, though, and stick with classic shades of navy, grey, and black.

Other places to wear your suit would be a day at the races, an evening at the opera, to the theater, or a formal dinner.
