While we'd all love to dishonestly claim that appearance doesn't account for much, we all acknowledge that, despite our best efforts, we use appearances to make judgments and assumptions, especially in the professional arena.

Any lack in your appearance, consequently, will negatively influence the employer to not consider you further. By putting your best foot forward you are demonstrating your professionalism, organization, confidence and capabilities and you stand a better chance of gaining employment.
Remember, image is everything, and perception is reality. Make sure your image conveys an accurate perception of you.
