Hose are a must. Do not wear hose with patterns or lines. Wear nice shoes. Preferably a nice pump that is not open at the toe or heel. Hair should be neat , clean , and in current style that compliments facial features.
Ladies be aware of off color or contrasting roots.
Men's hair should be short, not long. The longer it is, the more it hurts your chances of getting the job. Men should also shave or trim a beard or mustache. Nails should be well manicured and trimmed to an acceptable length. Polish should only be worn if the person has time to maintain it.
