In 1989 or so, I was serving as a professional staff member and staff scientist for a House committee when some of us went to the House floor. A member of Congress noticed that the top button of my dress shirt was unbuttoned, even though I was wearing a tie on top of it. He complained to the sergeant at arms, and I was ejected from the floor.

At that moment, I realized what certain parts of our nation’s leadership truly cared about, and I left congressional service shortly thereafter. The nation will be better served if the White House’s evolving sartorial views [“In tech world, not all are well suited for suits,” The Switch blog excerpt, Aug. 21] reflect a growing realization — in all branches of government — that what a public servant knows really is more important than how he or she is dressed.
