There is no such thing as a moral dress. It’s people who are moral or immoral.
Jennie Jerome Spencer-Churchill (1854-1921) American-British socialite [Lady Randolph Churchill]
Quoted in London Daily Chronicle (16 Feb 1921)
In response to a Philadelphia clergyman dictating that for a gown to be "moral" it must be cut no more than 7½" off the ground or 3" below the neck.
