A long-sleeve T-shirt is a type of shirt in the style of a T-shirt, which the original kind is short-sleeved, but with long sleeves. It has been an acceptable piece of fashion since the 1970s. Since the mid-1980s, it has often been worn underneath a short-sleeved T-shirt for a nice-looking, warm combination. That style is typically done in the fall and winter. T-shirts were originally worn as undershirts. This still occurs, but T-shirts are now also frequently worn as the only piece of clothing on the top half of the body (except that women usually wear a bra beneath it).
