Underwear is the Byproduct of the French Revolution
The aristocracy invented it to restrict genital mobility and restore penile law.
The first design was known as the "French Cut."
By spreading the buttocks and holstering the genitals, man was tamed.
But the people rebelled.
Nothing says freedom like full frontal
So we took a silky soft liner and doubled, nay, trebeled down on the crotch room.
Combining the feel of nudity with the function of a fanny pack.
