What to Wear to a Wedding Guest: Men Over 40

Wedding guests in semi-formal attire walk a line between polish and celebration, and men over 40 typically have the advantage of well-fitted tailoring and quality fabrics that photograph well. A suit in a refined navy, charcoal, or textured weave paired with a crisp dress shirt and silk tie meets the cocktail-level expectation without venturing into black-tie formality. Focus on a clean, structured fit through the shoulders and a tapered trouser that sits at the natural waist for a sharp, age-appropriate silhouette.
