How did the T-shirt get its name?

Take a look at the T-shirt silhouette on the right? Does it remind you of any letter in the alphabet? Possibly . . . . a T? Spot on! Some early, brilliant-like-you, unknown individual in the early 1900s also noticed that resemblance.
Nobody knows exactly when the first T-shirt was produced, but there is documentation dating back to as early as 1913 that the U.S, Navy adopted the crew-necked, short-sleeved, white common undershirt to be worn under overalls. Do you know why the Navy switched to T-shirts?
a) To keep the outer shirts from scratching and itching naval personnel? No.
b) To keep sailors warm while sailing in frigid weather? No.
c) To be worn under overalls to conceal the sailors’ chest hair. Yes! Don't ;laugh. That is the reason T-shirts were adopted by the Navy.
