T-shirt historical development
T-shirts were originally underwear, but were actually lapel and semi-open-necked shirts. Later, they developed into outerwear, including two series of T-shirt undershirts and T-shirt shirts.
There have been divergent opinions on the origin of the name of the T-shirt. One theory is that the dockers who unloaded tea in Annapolis, Maryland, USA in the 17th century wore this short-sleeved shirt. People abbreviated “Tea” as “T”. This kind of shirt is called T-Shirt or T-shirt; the second theory is that in the 17th century, British sailors were ordered to add short sleeves to the vest to cover the armpit hair to avoid unsightly; another theory is that the sleeves It forms a “T” shape with the upper body, that is, its clothing is a T-shaped stitched collar, hence the name.
In 1913, the U.S. Navy required sailor collar short-sleeved white undershirts to be worn in sailor overalls. One of the reasons was to hide the thick chest hair of sailors.
