It’s cold outside, which means it’s time to layer up (obviously). So, you throw on your sweaters and jackets and gloves and whatnot. But, what are you wearing underneath all that? What’s the first layer of clothing? Probably a t-shirt on most days, I would imagine. That’s not the full answer, though. What KIND of t-shirt? Many people think the t-shirt they wear to the gym is the same t-shirt they can wear out is the same t-shirt they can wear under a sweater. Tsk tsk. The undershirt is SPECIFICALLY created for the third example. It is UNDERshirt, after all. Undershirts are usually simple: one solid color, usually white. Keep in mind: simple is, 99% of the time, classy. You don’t need slogans on your t-shirts, especially if they’re going under all those layers. The fit is mighty important as well. Normal t-shirts will make you look bulkier, whereas undershirts will fit snug and keep you warm. I have TONS of undershirts. These days, I literally wear one every single day. It’s easy, classy, and sensible, and those three rarely go together.
