tennis tail
n.— «Like in the original Lacoste’s design, sometimes a tennis shirt is cut so that the back hangs a few centimeters lower than the front also known as a “tennis tail.” The longer tail is meant to keep the shirt tucked into the back of a man’s tennis shorts when he is bent over to survey the court.» —“How tennis and polo shirts came about” by Jay Pow Fibre2Fashion.com Sept. 10, 2007.
