Because teeshirts were originally undershirts made to be worn under dress shirts. Those teeshirts you buy in the Kobe Bryant Lower Merion Finest Shirt Apart from…,I will love this men’s underwear section next to the boxer-briefs and tighty-whities- they’re undershirts!! The ribbed, sleeveless tank-top is the other main sort of men’s undershirt. It’s not a t-shirt but an undershirt, and it typically white. Just like underpants, an undershirt is considered to be an undergarment. It is considered to be bad taste not to wear an undershirt unless you are dressed rather casually. For example, you don’t have to wear an undershirt under a t-shirt, but you should wear an undershirt under a dress shirt. A plain white t-shirt without any image is considered an undershirt. Thus, it is improper to wear a plain white t-shirt in public.
