Ever wonder why
there’s a teeny-tiny pocket above the regular ones in the front of your jeans.
It’s a watch pocket, originally for men who wore pocket watches and needed a
protective place to store them. Though, as Levi’s points out, the pocket has
also served many other purposes over time, from condom storage to coin
hoarding.
Levi Strauss, the
man who invented jeans back in 1873 for the invention of that extra pocket. A
blog post on Levi's website confirms this, saying that, early on, Strauss’s
jeans were given a small pocket which was designed as “protection for pocket
watches.” These are designed for cow boys.
