Well-bred obscenity
The ability to waltz today seems to be a sign of aristocracy, and after all some two centuries ago this dance was considered completely indecent. In Russia, the waltz was under strict prohibition, which secured the order of Paul I to the military governor of St. Petersburg Alexei Arakcheev on December 1, 1797. Together with the waltz, the emperor forbade other "indecent phenomena": the wearing of whiskers, tail coats, and "jackboots, referred to as boots." In pristine Britain, until the middle of the 19th century, dance, in which partners approached each other very closely, was condemned by the official press and the clergy. So even the Queen Victoria, who ruled at that time, did not advertise that she actually loved to waltz. In 1834, for the first time, the waltz was publicly danced in the USA, in Boston, and outraged public figures called the dance "indecent and violating any decency".
