Start the celebration as soon as guests arrive by throwing a short (no more than an hour) preceremony cocktail party. It will give everyone a chance to mingle and ensure that even your chronically late college roommate will get there in time for the main event. Keep it simple by serving a festive cocktail or two and a small treat like artisanal popcorn in paper cones. As for whether you choose to make a special guest appearance yourself—possibly in another cute white outfit—that's up to you.
