There is no generally agreed definition of ''business casual''. One definition of business casual states that it includes khaki pants, slacks, and skirts, as well as short-sleeved polo shirts and long-sleeved shirts, but excludes jeans, tennis shoes, tight or short skirts, T-shirts, and sweatshirts. Another source, an American university careers service, states that business casual consists of neutral colors more towards the dark shades of black, gray, navy, but can include white and off white, and reminds that the clothing should be pressed and have clean, crisp seams. The ''Dress for Success'' advice from the University of Toronto sums up business casual as ''a classic, clean cut, and put together look where a full suit is not required,'' which means slacks, khakis, or skirts; blouses, polo shirts, or shirts with collar but no necktie; some sweaters; and closed-toe shoes. The Canadian university ends with the warning that ''it is not clothing you would wear to a club or for athletic purposes... Don't let the word casual mislead you. You still need to look professional.''
