Before the 17th century, men were always going commando. Underwear was not a part of a man’s wardrobe in history before that. Even once the 17th century began, men’s underwear was not the best. It mostly consisted of an extra part of the shirt that tucked under the pants. It was not until the 18th century that men began to wear what we would commonly think of as ‘men’s underwear’, where things like long johns, boxers, and briefs became more common. At least it made laundry day easier before the 17th century!
