According to modern etiquette rules, a wedding invitation is properly worded when it is tasteful, grammatically correct, and includes essential information such as the hosts' names, the names of the bride and groom, and the time and location of the ceremony and/or reception. Traditional wording is recommended for formal affairs.
Formal wedding invitations use full names with titles, while informal wording often leaves out middle names and titles. Dates, locations and titles except for Mr. and Mrs. are traditionally spelled out rather than abbreviated. Informal invitations may spell out the time but provide a numerical date, or may follow formal etiquette rules and spell everything out.
Formal weddings that take place in a religious setting are worded with "the honor of your presence," while "the pleasure of your company" is traditionally used to signify a non-church ceremony. Phrases such as "share in our joy," "join us" or "you're invited to attend" are acceptable wording for informal events.
Guests are not required to respond to an invitation to a wedding ceremony, but RSVP information may be included in the lower left corner if the celebration involves a reception. Various formats of the acronym are acceptable, as well as the phrase "The favor of a reply is requested." Phone numbers, email addresses and other means of contact may be listed in this corner as well.
