But then came the polka, the dance so popular that mid-19th century Europe came up with the word “polkamania” to describe its own excitement. As the polka craze swept west across the continent, enthusiasts claimed the polka jacket, then the polka hat (neither of them spotted), and finally, the polka dot. There is only a tenuous connection between dot and dance, yet surely the two are linked—it’s possible that polka dots reflect the same regulated, short bursts of energy that inflect the polka itself. Regardless, we know that the American women’s magazine Godey’s Lady’s Book was the first to print the term, in an 1857 description of a “scarf of muslin, for light summer wear, surrounded by a scalloped edge, embroidered in rows of round polka dots.”
