Someone puffed up with his own importance but really having little effect on the lives of others. It is often used as an insult to disparage others who really
don’t deserve the title. The true empty suit, which conjures up the image of a business suit of clothing without a person, really doesn’t know what he or she is doing. He or she is ineffectual, perhaps a
phony, and is about as relevant or helpful as a suit hanging on a
rack.
To call someone an empty suit implies that you think they are a complete waste of
time. Editorials on politicians love to use the term empty suit to describe
people seeking presidential office. This or that politician is just “an empty suit,” to quote the words of numerous political critics, and is thus undeserving of our attention.
Some politicians do deserve the title. A senator with a very
poor voting record, or
failure to attend senate sessions could clearly be called an empty suit because he is not really performing the job for which he was elected. On the other
hand, some politicians
may advertise themselves as “not just an empty suit” in order to distinguish themselves from their implied empty suit peers.
