My Prof of Oral History tells the story of his Grandpappy durring World War II. Seems that in that timeframe Women began regularly wearing Pants:

The Prof wouldn't make it these days.

. . . "and the action there reminded me of two pigs fighting in a totesack."

That image has also been described as "two pigs in a poke".
