Q. What is the proper form of response to a formal invitation to a very small wedding where the reception is the featured event? The large reception invitation and smaller wedding invitation were received in the same envelope, separated by tissue paper, but only the reception invitation had "The favour of reply is requested" engraved on it. There was no customary reply envelope included.
A. Receiving the wedding and reception invitation in the same envelope is prefectly OK - an RSVP card is most often included but is not a prerequisite for asking for a response. You will seldom find that you are requested to confirm the wedding but in nearly all situations(especially if the family is wise to the cost of a reception) you will have an RSVP or "the favour of a reply is requested". When a reply card is not included with an RSVP you should either call the family or drop a note of your intention.
