For some, it’s about comfort; for others, it’s a matter of taste. But the age-old question remains, “Do you need an undershirt in the summer?” While there are a few different factors, you’re mostly choosing between sweat absorption or added heat. In this guide, we’ll break down the case for and against wearing men’s undershirts during the summer months and offer a few alternatives if you choose to do so.
Pros of Wearing an Undershirt in Summer
TL;DR – Your undershirt can…
- Absorb sweat, conceal sweat marks
- Keep deodorant off the fabric
- Prolong the shirts lifespan
Men’s undershirts absorb sweat. This means you run a lower risk of looking sweaty, even if you are feeling sweaty. It prevents unsightly stains that awkwardly pool around your armpits and occasionally under your pecks. Stopping sweat and keeping deodorant off the fabric helps keep the shirt clean. It can also prevent the need for additional washes or dry cleaning, prolonging the shirt’s lifespan. Lastly, if you wear sheer fabrics, an undershirt can add some opacity that prevents the garment from being too see-through.
Reasons to Skip the Undershirt in Summer
TL;DR – Your undershirt can…
- Trap heat
- Disrupt your silhouette
- Peek out depending on the cut your shirt
The most obvious reason here is that you’re adding a layer. This traps heat as well as moisture, especially if you tend to sweat a lot. Some undershirts can add bulk to an outfit, creating a less clean silhouette. Depending on the cut of your undershirt, some of the fabric can be visible if you’re wearing the top button or two undone. Depending on taste, you might not want a visible undershirt.

When You Should Wear an Undershirt
TL;DR – Wear one if…
- You sweat a lot
- You wear a very fine or sheer shirt
- You have a formal meeting or interview, etc.
- You wear a dress shirt more than once before washing
It’s always a matter of preference, but wearing an undershirt can elevate your overall appearance and keep the dress shirt cleaner. If you’re prone to sweating, have a big meeting, or don’t wash your shirt after every wear, you might want to consider one regardless of the outside temperature.
How to Choose the Right Summer Undershirt
TL;DR – When selecting a summer undershirt, consider
- Lightweight, moisture-wicking fabrics
- A close fit to avoid excess bulk
- A v-neck or scoop neck if you’re skipping a tie; this keeps this
Best Alternatives to Wearing an Undershirt
TL;DR – If you skip an undershirt, you can stay cool by…
- Selecting breathable fabrics like linen or linen-blends
- Using sweat pads or wipes
- Choosing dress shirts with built-in lining or double-weave panels
There’s a long list of things you can do, but if sitting directly next to the AC isn’t an option, you’re best off shopping fabrics developed for and perfected in hot climates. Sweat wipes can offer some temporary relief too.There’s a long list of things you can do, but if sitting directly next to the AC isn’t an option, you’re best off shopping fabrics developed for and perfected in hot climates.
