What can a man wear to a wedding instead of a suit?

Smart separates offer a stylish alternative to a traditional suit while still looking appropriate for a wedding. A navy or grey blazer paired with tailored trousers in wool, cotton or a blend works for most daytime and evening events. Chinos in navy, khaki or olive can be dressed up with a crisp shirt and a smart jacket, especially for summer or outdoor weddings. A waistcoat adds structure and can be worn with or without a jacket for a layered look. Footwear should be clean leather shoes or smart loafers, and avoid trainers unless the couple has explicitly said casual wear is welcome. Shirts in white, light blue or subtle patterns keep the outfit refined, and a tie or bow tie can raise the formality when needed. Fabric choice matters, so choose breathable materials for warm weather and warmer weaves for cooler days. Always check the dress code on the invitation, since expectations differ by venue and culture. If you are unsure about any religious or cultural requirements, it can vary, so ask the couple or check with the register office or place of worship if relevant.
