For Women Dressing appropriately for the job interview can make the difference between being hired or not. This is the interviewer's first impression of you. She will make an initial decision in the first FOUR seconds of your meeting. It is important to dress properly even when going in to just pick up an application or drop off your resume.
Men Avoid fads and high fashion.
Your appearance should be conservative. You want the interviewer to concentrate on your abilities rather than your clothing. Be sure that you feel comfortable in the outfit. Try it on before the interview to decide on the proper color shirt, tie, belt, fit, etc. If you are on a tight budget you should be aware of the fact that inexpensive suits look better in dark colors.
