Did You Know?
If you're invited to a ball or other social function and the invitation includes the French phrase costume de rigueur, you are expected to adhere to a very strict dress code-typically, a white tie and tails if you're a man and a floor-length evening gown if you're a woman. In French, de rigueur means "out of strictness" or "according to strict etiquette"; one definition of our word rigor, to which rigueur is related, is "the quality of being strict, unyielding, or inflexible." In English, we tend to use de rigueur to describe a fashion or custom that is so commonplace within a context that it seems a prescribed, mandatory part of it.
