You know that little pocket on your jeans? The one that doesn't really function as a pocket due to its tiny, tiny size, that sits inside an actual pocket, which does actually function as such? Well that tiny little pocket inside a pocket is actually for watches, designed for cowboys in the 1800s. According to the Levi Strauss website, "Originally included as protection for pocket watches, thus the name, this extra pouch has served many functions, evident in its many titles: frontier pocket, condom pocket, coin pocket, match pocket and ticket pocket, to name a few."
