I tried to abide by the saying, “Don’t dress for the job you have; dress for the job you want.” It made sense and I was promoted often. Also, while working in H.R. for many years (God help me!) I read articles in professional journals showing that it’s been proven that the better people dress, the better their performance — across the board, no matter what the job.
Not surprised at all. Another simple rule of thumb is to dress to the level of your immediate supervisor.
