When its time to order your invitations, you will need to know how to word your invitation. This can be really confusing if there are multiple parents involved in your wedding along with multiple enclosures. Keep your invitation simple and cut out the cost of postage by sending only the necessary enclosures such a RSVP with envelope. Any other information (ie. hotel and flight information for a destination wedding) can be conveyed by a wedding website. Listed below is a wording sample to help you make your own unique wording. More information can be found in Miss Manners on Painfully Proper Weddings by Judith Martin.
A general lay out of an invitation is as follows but there are many variations on this format. You can always change any of the sections to include multiple parents of the bride or add the parents of the groom after his name.
