Undershirts are a wardrobe staple, useful under any type of clothing. The classic men's undershirt style is the t-shirt, which can move easily between being underwear and outer ware. Under dress shirts or even casual shirts, a t-shirt creates a neat appearance, providing an opaque layer under thinner shirts, absorbing sweat and adding a level of comfort.
When it comes to comfort, nothing beats cotton. Cotton is a natural fiber that is hypoallergenic, breathable, durable and soft. Cotton tees add a layer of warmth without bulk and get softer with every wash. There are literally hundreds of styles to choose from. If you prefer to keep your undershirt under wraps, go for a vee-neck tee. And you can't go wrong with the traditional crew neck style, perfect under a shirt and tie. Some brands offer pure 100% cotton tees, while many modern styles include some spandex for a close, smooth fit. These stretch cotton undershirts hug the body and are great under knit or slim-fit shirts. Cotton tee shirts are offered in the traditional white, but it's handy to have some alternatives in your wardrobe too, like gray, black and navy.
