Who knew planning a wedding would have so many moving parts—and include so many people? To help you figure out who does what, we've put together a list of all the major players in your wedding day. (Keep in mind that most roles can be played by either gender—why not have bridesmen and groomswomen?—and by as many people as you want.) You'll want to ask your VIPs to be in the wedding party early in the planning process, so be sure to think about the family members and friends you'd like to include in your crew.
