A lot of talk goes into female underwear, but with guys it usually boils down to boxers or briefs.. or neither *wink wink*. But that wasn't always the case, as this new video by Mode.com exploring the evolution of men's underwear over the last century shows — model John King is hear to give you a solid history lesson. 

Back in the early 1900s, guys wore flannel Long Johns under their clothes, that came with a little poop flap and penis opening:

By the the '30s, a postcard of a guy wearing legless swimwear in the French Riviera allegedly led to the design of less constricting underwear — Jockey briefs and a vest. 

In the '50s, guys started wearing their T-shirts outdoors, and donned boxer shorts with elastic bands that made it comfortable to move around. 

Later, companies started experimenting with designs that were colorful, flashy, sexy and filled with personality, one of the best examples of this fun-loving trend being Joe Boxers. 

And now? Well, pretty much anything goes.
