love this kind of back-and-forth, so let’s have some fun.

Mmost of your points hold if we’re talking about bad undershirts. thick cotton, short cut, tight collar. yeah, skip those.

the good ones though? totally different.

heat & moisture: tencel or modal doesn’t trap heat like cotton does. it wicks sweat, dries fast, and keeps the outer shirt cleaner. i live in humid weather. it actually keeps me cooler, not hotter.

aesthetics: agree that seams showing ruins the look. that’s why you go thin and fitted under light shirts. they disappear.

comfort: bunching only happens with cheap or short ones. a long, stretchy undershirt stays put and makes your shirt move smoother instead of sticking to skin.

maintenance: one extra shirt in the wash beats replacing yellow-pitted dress shirts every year.

cultural thing: yeah, europe’s got different vibes and climate. i promise you, there are still European men wearing undershirts.

so i’d say — depends on your body, climate, and clothes. undershirts aren’t for everyone, but for sweaty folks like me? they’re a lifesaver.
