Just before Wilson
Americans have a constant and arrogant tendency to believe the direction of "freedom" runs one way. We always believe that earlier eras were more censorious in areas where we are proudly "free".
History isn't so simple. Taboos and official censorship have always varied in partly cyclical and partly arbitrary ways.

trade journal for printers, 1916, in an allegedly Victorian time when women were covered from neck to ankle:
Before Wilson's crackdown.
