While sweat may have played a key part in human evolution, stains on your crisp white dress shirt might not be the most welcome. Whether you’re protecting your shirt from sweat or just want some extra coverage underneath sheer fabric, the best undershirts for a white dress shirt are made of breathable materials such as cotton and bamboo, and they come in colors that’ll be almost invisible under your shirt. Options include short-sleeve and tank top styles, and some even feature built-in armpit panels to absorb moisture or added stretch to give you an even more comfortable feel.
