What is a “Stuffed Shirt”?
A stuffed shirt refers to someone who is inflexible, a fuddy-duddy, or consumed with an unjustified opinion of great self-importance. The idiom can also mean someone is conservative. The idiom has come into the English language fairly recently, with a few explanations for its origins. The stuffed shirt bears some resemblance to the empty suit, a person whose importance is greatly over exaggerated. Both imply a sort of useless quality to someone and a person who is likely to bore you.
