A formal dress can look professional too and make you look super chic that too in professional terms. Wear a dress once a week to change your boring pant suit or trousers look and give yourself and others something fresh to look at. A good smile makes a nice first impression but the eyes can do wonders too. Well rested and prettily done eyes can make you look in control and command than the bloodshot ones that displays how much sleep deprived you are.
