The first piece is of course the invitation itself, which includes of course the date, location and time of the wedding ceremony amongst other things.
The invitation suite also includes the outer envelope, RSVP card and RSVP envelope. If you are offering menu options to your guests be sure to include this selection on the RSVP card and of course the RSVP date!
These four pieces, invitation, outer envelope, RSVP card and RSVP envelope, make up the basic invitation suite. Today it is also common to include additional pieces such as a map and directions card and accommodations card for all of your travelling guests. You can also swap in an RSVP postcard to save paper and postage ~ going green is always in style!
