An undershirt is a garment worn underneath other clothing, typically to absorb sweat and provide an extra layer of warmth. Think of it as your first line of defense against discomfort. It can be a t-shirt, tank top, or even a long-sleeved shirt. The purpose is to keep your outer clothes clean and fresh. It can help regulate body temperature and prevent chafing. An undershirt might be unnoticed, but it plays a crucial role. It is like the unsung hero of your wardrobe.
