T-shirts have been an age-old comfort wear all around the world. But have you ever wondered how old actually is the history of this particular style of clothing? T-shirt evolved through cutting the one-piece undergarments used in the 19th century into separate top and bottom garments. The top used to be long enough to tuck under the waistband of the bottoms.
However it became popular in the United States during the Spanish American war, after they were issued by the U.S. Navy. T-shirts were actually a slip-on garment without buttons or collar, usually with short sleeves and frequently a round neck line. The garment got its name due to the shape of its outline; it soon became popular in various industries, including agriculture as a bottom layer of clothing for workers.
