Which dress style is less formal than a suit and tie and might include khakis and a polo?

• A. Business casual
• B. Casual
• C. Smart casual
• D. Formal attire

Answer: (A)

Understanding dress codes means comparing levels of formality. The style that sits comfortably beneath a suit-and-tie standard is business casual. It allows neat, professional-looking pieces without requiring a suit. Khakis or chinos paired with a polo shirt or a button-down shirt are classic examples. You can add a blazer or sport coat and polished shoes, but the overall look remains relaxed compared to formal attire. Casual would drop the formality even more, often including jeans or t-shirts; smart casual sits in between, a bit more refined than casual but not as formal as business casual; formal attire is the highest level, requiring a suit and tie or more. So the option described matches business casual because it provides a professional but relaxed look that can include khakis and a polo.
