Etymology

Origin of impropriety

From the Late Latin word improprietās, dating back to 1605–15. See im- 2, propriety

Explanation

Impropriety is a violation of a rule of behavior, manners, or etiquette. So while it is fitting and proper to wear a bikini top and a sarong to the beach, to do so at church would be considered an impropriety. Some find a bit of impropriety charming. Somerset Maugham went so far as to say, “Impropriety is the soul of wit.”
