Whether attending a wedding or heading to an important job interview, you’ll want to ensure your suit game is on-point at any formal event. Many men wonder whether they need an undershirt with their suit.

An undershirt is more than just an article of clothing; it enhances comfort, absorbs sweat, and increases the lifespan of your shirts. It will protect your expensive clothing, providing a defensive layer between your body and your dress shirt.

6 Benefits of Wearing an Undershirt

There are several benefits of wearing undershirts with dress shirts and suits, including the following:

1. Comfort

Wearing an undershirt is as necessary as your mattress wearing a fitted sheet. You could undoubtedly sleep without it, but you won’t be as comfortable!

An undershirt provides a soft second skin while also protecting your skin from the likes of an uncomfortable dress shirt. This extra layer will also prevent chest hair from showing through your shirt, making you feel more relaxed and comfortable.

2. Look slimmer

Who would’ve thought wearing extra clothing could make you look slimmer?

A slim fitting undershirt streamlines your body, preventing your shirt from untucking throughout the day, maintaining a sleek, fit build. Some even say the quickest way to lose a few pounds temporarily is to wear an undershirt!

3. They offer warmth and thermal insulation

Undershirts can adapt to climate, meaning they help regulate your temperature. During the winter, undershirts offer a layer of insulation that will keep you comfortable and warm. And in the summer, undershirts can absorb heat and prevent sweat marks.

4. Avoid deodorant stains

There’s nothing more disappointing than picking out your crisp white dress shirt only to notice it’s a little too crisp under the armpits! An undershirt protects your dress shirt like a shield, allowing you to show off your white shirt at restaurants, meetings, and events, without the fear of stains!

5. Make suits fit better

If your suit looks too big for the shirt underneath, you may wish to opt for a jumper or crew neck. However, an undershirt provides an extra layer underneath your shirt, giving you the added padding you need to fill out your suit.

6. Prevent perspiration stains

For stains to develop on your clothes, you don’t have to sweat profusely. The good news is that men’s undershirts will absorb sweat and heat, eliminating any chances of odor and stains.

Tips On How To Wear An Undershirt

Now you know more about the benefits of wearing an undershirt, let’s provide you with some top tips on doing so:

Wear crew neck undershirts

This figure-hugging undershirt can protect you from cold weather, as well as keep you cool when it’s hot and humid outside.They are a great addition to your outfit, but only if the neck opening isn’t too revealing. Otherwise, you may see it underneath.

This is why men typically wear collared shirts with a crew neck undershirt.

Opt for a deep V-neck undershirt

V-neck undershirts will always be our first go-to recommendation. Thanks to their low cut, the outfit opportunities are endless. The thoughtful design allows men to wear their buttons undone without revealing the V-neck.

Pick a color lighter than your dress shirt

Your dress shirts should never reveal your undershirt. Light-colored dress shirts would require a white undershirt, and vice versa with a black undershirt.

However, you can also opt for an invisible undershirt to go with your outer shirt, preferably beige, which will blend with your natural skin tone.

Avoid using a T-shirt as an undershirt

Many people think that tee shirts are a perfect substitute for undershirts. This is not the case. T-shirts aren’t designed for this purpose. They are too thick, and they have no stretching properties. An undershirt is not your standard T-shirt; it has been designed to be worn as a defensive barrier between your skin and clothes.

Your undershirt should not be visible

Our final advice is to ensure that your undershirt is not visible. It’s not designed for aesthetic purposes. It’s intended to be hidden. Here are some of the things you can do to prevent your undershirt from showing:

  • Make sure that you always purchase the correct size
  • Opt for a deep V-neck if you like to leave your collar unbuttoned
  • Consider wearing a beige undershirt, or gray for darker skin tones
  • Get a thicker formal shirt if the one you’re wearing is too thin and shows everything underneath

What Undershirt Should You Buy?

Your undershirt will depend on the outfit you wish to wear, the color, and even the event you’re going to. But whatever it is you need, we’ve got you covered, literally, at Underfit. Shop our range of undershirts today.

FAQs

How many undershirts should a man own?

It depends on your lifestyle. If you have a formal job and wear a suit daily, it makes sense to have around two weeks’ worth of undershirts.

Do undershirts make you hotter?

No, undershirts are designed to provide effective insulation, keeping you cooler during the summer and warmer throughout the winter.

How do you wear an undershirt without it showing?

We would recommend avoiding deep necklines. Plus, gray is a good color for an undershirt, rather than always turning your trusted white undershirt.

Should men wear undershirts in the summer?

Yes, undershirts are great for the summer months. You can wear them with dress shirts, as well as your polos and casual t-shirts. They will ensure you feel comfortable in hot weather while stopping sweat from reaching your outer clothing.

Final Thoughts

So there you have it: everything you need to know about undershirts and how to wear them properly. Keep comfortable, look slim, and make sure you never have to worry about sweat marks again!
