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 author wrote in the Financial Times that "Ordinarily business casual for guys seems fairly clear. It is a pair of chinos, a blazer and a good shirt, no tie."
A contributor to Forbes asked her Facebook friends to define Business Casual, and found an apparent consensus on "For men: trousers/khakis and a shirt with a collar. For women: trousers/knee-length skirt and a blouse or shirt with a collar. No jeans. No athletic wear.", although a response to that was "I disagree. No khakis." She states that "there’s a lack of consensus in what actually defines a business casual wardrobe. All most people know is they don’t want to see too much of a colleague’s body, including feet."
