There are several options that men can wear under a suit, each with its own set of benefits and drawbacks. Here are some popular options include:

Dress shirt

Most people love to wear a cotton dress shirt under their suit. It looks formal, classy, and professional. It can help to absorb sweat and prevent sweat stains on the outer shirt. Dress shirts are typically made of lightweight, breathable fabric like cotton or linen, and it has a collar and buttons down the front. A button-up shirt fits well if made by an expert tailor.


T-shirt-under your suit

You can wear a T-shirt underneath your suit. As a casual outfit, a T-shirt can be a great choice. Though it is comfortable to wear, it is not suitable to wear on a formal occasion like a dress shirt. Usually, T-shirts are made of lightweight, stretchy fabric like cotton or polyester, with short sleeves and a round neckline.


Vest-under your suit

A vest is my favorite choice to wear with my suit jackets. Though wearing a vest depends on the occasion, men surely loved it. A vest is a sleeveless garment worn over a shirt or under a suit jacket. It can add an extra layer of warmth and can be dressed up or down depending on the occasion. A vest is typically made of lightweight, breathable fabric like cotton or wool and has buttons down the front.


Turtleneck-under your suit

Generally, a turtleneck is worn in a winter session. It's a kind of sweater that covers the neck and part of the chest. It can be a stylish and sophisticated choice, but it may be too warm for some people. A turtleneck is usually made of a thicker, insulating fabric like wool or cashmere and has a high, close-fitting neckline.

Polo shirt

A polo shirt is a perfect choice to wear under a suit in the summer or hot weather. It is a casual shirt with a collar and a placket of buttons down the front, and it has short sleeves and a ribbed collar and cuffs with a versatile option that can be dressed up or down depending on the occasion. Rather than T-shirt and tank top, you can also wear a polo shirt on formal occasions. Usually, it is made of lightweight, stretchy fabric like cotton or polyester.

Tank top

A tank top is a sleeveless shirt that can be a good choice for hot weather, as it provides ventilation. You can pick a tank top to wear under your suit in the summer. However, wearing a tank top on any formal occasion will look funny, so wear this only in a casual and friendly environment. Typically, this is made of lightweight, stretchy fabric like cotton or polyester and has thin straps that go over the shoulders.

Factors to consider Choosing the right one

Should we wear anything under our suit? Obviously, NO. When deciding what to wear and what to not, we should focus on the points below to make a great decision. Here are several factors to consider:

Is it comfortable

If you wear anything that is not comfortable to wear, then it will ruin your day. Because you may need to wear them for the whole day, look for options made of breathable materials like cotton or bamboo, which can help keep you cool and prevent sweating. Avoid anything made of synthetic materials like polyester, which can be hot and sticky.

Find the right fitting

Make sure what you are going to wear is fit well and is not too tight or too loose. Wearing anything tight can be uncomfortable and create visible lines under your suit. This may cause you suffocation. While loose undergarments can bunch and wrinkle. So, try the best tailor to cut your suit for the perfect fitting.

Ensure the breathability

Sweating can be a problem when wearing a suit, especially in hot weather. What you are wearing under your suit will play a vital role in this case. So choose anything made of breathable materials like cotton, which can help keep you cool and prevent sweating.

Avoiding visible lines

What if you wear something under your suit and the lines are visible? This could create an awkward situation. So wear something that won't create visible lines under your suit. Ensure that what you wear fits well and doesn't bunch or wrinkle. Try to avoid wearing anything with thick seams or bulky details that may be visible under your suit.

Style and looks

Consider the overall style of your suit and decide the right option that complements it. For a formal look, a dress shirt is the best choice. T-shirts or polo shirts will be more appropriate for a smart casual look.

Is it right for the occasion

Occasion matters on what to wear and what to not. Think about the occasion you will wear your suit, and pick the appropriate one. A dress shirt is the most suitable choice for a formal business setting. A T-shirt or polo shirt is a good choice for a casual occasion.


When wearing a suit can make a big difference in both the appearance and comfort of your outfit. Whatever you wear under your suit, think about the occasion, session, dress code, and dress shoes. Whether you opt for a classic dress shirt or a more casual T-shirt, there are plenty of options to choose from.
