The modern day t-shirt can be traced back to undergarments worn in the 19th century. The popular onesies called 'union suits' were split up in a top and bottom garments. Miners began using the top undergarments as shirts, because they were a good to wear in hot environments.
However, the t-shirt did not become popular until around the time of the Spanish American war. The US Navy issued white, short-sleeved crew necks that were supposed to be worn under the uniform. Sailors and Marines would remove their uniform jacket and wear only the undershirt.
While the t-shirt was originally meant to be an undergarment, it's now probably the most popular piece of clothing in the world. The first decorated t-shirts were made by a company called Tropix Togs which made shirts licensed by Disney.
