Business casual attire for men is a dress code that is not overly formal or restrictive, focusing on comfort and versatility. It allows for a focus on silhouettes and fit rather than patterns and colors. Blazers, well-tailored, are key components of a business casual look. Sneakers can be incorporated when balanced with a more formal top, and jeans in darker washes and straight cuts can be a solid choice. Sweaters and cardigans in solid colors or neutral tones are also ideal. Loafers are a great footwear option. Stick to neutral-colored or small-print shirts and dress pants in neutral colors and pleated styles.
