Business / Informal Business and Informal attire is more sophisticated than Smart Casual, often signaling the need for suits, ties and dresses. For Him: Wear a business suit with tie. You may also opt for nice slacks with a sports jacket and tie.

A dress code that is more formal than smart casual is Business Casual or, more formally, Business Professional. While smart casual allows for a mix of polished and relaxed pieces—such as dark well-fitted jeans with a blazer or a stylish midi dress with fashion sneakers—Business Casual elevates the standard by removing denim and casual footwear. For men, this means tailored chinos or dress slacks, a collared button-down shirt (tucked in), and leather loafers or oxfords. For women, it includes tailored trousers, knee-length skirts, professional blouses, or sheath dresses. If the event requires an even higher level of sophistication, Business Professional (full suits and ties) or Semi-Formal (cocktail dresses and dark suits) would be the next steps up the formality ladder, ensuring a look that is authoritative and traditionally elegant.
