Traditional business formal is a dark suit for men and a dark pant suit or dress and blazer for women. While business casual has changed through the years, business formal attire is still the same, with companies expecting professional suits, ties for men and dress shoes for both men and women.
Men should wear white button-down shirts with suits. Any accessories should be high quality and kept to a minimum. Women should wear collared blouses with suit jackets and keep pantyhose neutral or black in color.
Business formal attire isn't always necessary, but professionals need to know when casual is appropriate and when formal is expected. Business meetings, client interactions and interviews are all times when business formal is the best way to dress..
