Dolphin shorts or Dolfins are a specific style of shorts for athletics. They are typically very short and were originally made from nylon with contrasting binding, side slits, and rounded corners, a style which was popular in the 1980s.
The name is a corruption of Dolfin, the American company that first produced the original running shorts in the 1980s.
One high-profile wearer of 'dolphin shorts' is the fitness guru Richard Simmons, who in 2012, boasted of owning 400 pairs of vintage Dolfins.
In 2012, it was reported that orange Dolfin shorts are specified as part of the uniform for waitresses at Hooters.
