At the beginning of the twentieth century, the T-Shirt quickly became an American favorite. Now, a century later, at the beginning of the twenty-first century, the T-Shirt remains as popular as ever.The T-shirt evolved from undergarments used in the 19th century. T-shirts became popular though the united states,These were a crew-necked, short-sleeved, white cotton undershirt to be worn under a uniform.
The American T-Shirt began during WWI when American troops noticed European soldiers wearing a comfortable and lightweight cotton undershirt during the hot and humid European summer days. Compared to the wool uniforms that the American soldiers wore, these undershirts were cooler and more comfortable and they quickly caught on with the Americans. Due to their simple design, these shirts became known in the USA as "T" shirts or, as we know them now, "T-Shirts".
By the 1920's, "T-Shirt" had become an official word in the American English language with it's inclusion in Merriam-Webster's Dictionary. By W.W. II, both the Navy and the Army had included the T-Shirt as standard issue underwear.
