Does it really make a difference how you dress for an interview? In many cases it does. Your goal is to dress in a manner that projects a professional, competent image, regardless of your employment level or career path. Think conservative!
For women: conservative navy blue, gray or black business suit (matched skirt/pant and jacket). Closed-toe shoes, no sandals, blouses, hose preferably, conservative hair, jewelry, makeup and perfume.
