"I mustache you a question, but I'll shave it for later."
No, we'll ask it now: How did something that has existed since the beginning of mankind become a thing?
The mustache fad, embraced by preteens and hipsters alike, still flourishes (despite a few cranks who'd take a sharp razor to the whole trend). Even now, in the heat of summer, people are still looking up mustache inspiration on Yahoo! Search, from [batman mustache] and [dog with mustache] to [mustache party] and [mustache party supplies].
How this mustache trend grew can be traced to retro yearnings from both hipsters and millennials, marketing mixed with politicking, a global charity event, and the power of Etsy.
