A professional appearance is important not only in an interview but also in internal and external meetings, and particularly when dealing with clients face to face. As the saying goes, you never get a second chance to make a first impression. This is equally true for yourself and for the company that you are representing. Whether you are the receptionist, or the mail room clerk, you must remember that you are not invisible to your clients, suppliers and partners. Maintaining a professional appearance does not stop with what you are wearing but directly relates to the verbal tones you use and your body language.
