You’ve probably seen them being worn under any number of button-downs and polos – those basic white tees known as undershirts. But are they just an unnecessary layer, or do they provide some legitimate benefits?
As a lifelong undershirt enthusiast, I say they’re definitely worth consideration for both style and function reasons.
Comfort and Protection
First off, an undershirt provides an extra barrier between your skin and any outer layers. This is nice for absorbing sweat to keep you feeling fresher throughout the day.
I’ve found undershirts also stop fabric rub from dress shirts and polos that could otherwise lead to chafing or irritation. In warmer weather, that added breathable layer wicks moisture away to keep you from overheating too.
In terms of protecting your button-downs, undershirts prevent deodorant or perfume stains from showing through on the underarms of light-colored shirts.
They also function as a shield against skin oils that could otherwise transfer directly onto and potentially saturate nicer fabrics over time. Basically, it’s a layer that preserves the pristine look of your wardrobe longer.
Sweater Insurance
If you live somewhere with fluctuating seasons, you know the struggle of deciding layers each morning. Undershirts solve this by allowing you to comfortably wear thinner sweaters or layers even on warmer days. Then, if it gets too hot, you have the option to strip down without exposing your bare skin or risking nipple headlights. Personally, they give me peace of mind on unpredictable weather days.
Invisible Texture
A final big perk of undershirts is that they effectively add texture and bulk under thinner dress shirts without really being seen as an extra layer. This subtly fills out sleeve and torso areas in a natural, unconstructed way. The result is a more polished, put-together silhouette. Even baggier button-downs take on a nicer drape and structure with a fitted undershirt tucked underneath.
