Attending a wedding as a guest can be both exciting and stressful, especially if it’s your first time. If you’re part of the program—say you need to propose a toast to the newlywed—everyone’s eyes will be on you, so you need to look your best. On the other hand, you want to show respect to the celebrants and not draw too much attention to yourself. You don’t want to upstage the bride or groom or break dress code rules.
