Yep, indeed. A rule all that much more critical when that unplanned someone you encounter that day you expected to be quiet and uneventful could be Congress, OMB, your Cabinet Sec’y or Agency Director, the President, etc.This rule applies not only to what one wears, as well, but also what condition it’s in; for me to wear anything to work I make sure it’s in top condition (not worn, snagged, rumpled, scuffed, etc); and I try to be very conscious as well of grooming–hair, no chipped nailpolish, etc. (or for men, either clean shaven or with neatly kept facial hair; no ragged looking stubble, etc).
