As semiformal's more casual sibling, "daytime semiformal" denotes a dress code suitable for country club or garden weddings—a midday event where the vibe is traditional but without feeling overly fancy. The key here is to communicate to your guests that you'd like them to be comfortable (especially if your wedding is outside), while also dressing up a little more than they normally would for church or a ladies' tea party or brunch. Women should wear lightweight dresses (cotton is fine), perhaps in a flora print, while men don the standard uniform of slacks and a sports coat. Or a seersucker or linen suit, as the case may be. And here's where we reach the great tie debate: Tie or no tie? Answer: Either! A less formal, daytime event leaves neckwear up to the wearer, although we might suggest a bow tie as a happy medium (and potential conversation starter).
