Smart casual occupies a broad middle ground — dressed-up casual without formality. Common in restaurants, social events, and creative workplaces. Jeans (dark, clean) can qualify; sneakers are acceptable if premium. The line between smart-casual and business-casual is blurred and context-dependent. Fabric priorities shift to comfort: jersey, cotton, linen, and stretch blends. In tropical climates, smart-casual allows looser silhouettes and lighter weights than business-casual.
