The ever-popular undershirt t-shirt is a must-have in every man's wardrobe. Undershirts are perfect to be worn under your regular shirt or suit. Whether you are wearing a casual polo and just need a shirt under it or whether you need a comfortable shirt under your suit and tie, an undershirt is essential. Undershirts are usually silky soft and comfortable next to your body. They have a smooth fit so they don't bunch under your clothing. It's up to you if you want your undershirt seen or not. If you want to hide an undershirt, go with a lower neckline. If you want it to peek out a bit, choose a higher neck with a few buttons undone. Undershirts are even great when worn as shapewear to streamline the figure under your clothing. Undershirts wick away moisture keeping you cool and dry, thus keeping moisture from your outer fashion.
