In the Navy, in business and in the classroom, one's initial appearance is important as a first step in commanding respect. Good grooming is a given. Then, I favor wearing a suit (or sport jacket and well pressed slacks), clean shirt (of course!),tie and shined shoes. Comments from my students show that my appearance helps them to decide that I am a professional. During demonstrations, the jacket comes off, the sleeves are folled up, and I project interest and excitement about the project.
