You don't have to have the looks of Angelina Jolie or George Clooney to nail the appearance component of presence. It comes down to what you do with what you've been given. The way you look, how you stand–posture (Mom was right, standing up straight is important), your smile, your health...do you take care of yourself? Your clothes, the quality, style, fit, colour and appropriateness for the occasion (believe it not flip flops are never appropriate for work, not even on casual Fridays). Luckily, this is the easiest of the three to master.
