Similarly you can also send rehearsal dinner invitations to invite people close to you for the rehearsal dinner party. By sending the invitations before hand you will be giving enough time for the guests to reserve that date so that they can attend the function. You can know about the details such as the time, date and venue of the shower by receiving the invitation in advance. Some people also like to send engagement invitations to notify their close ones about the engagement ceremony which can be conducted grandly by the host. If you are having a special theme shower, you can include instructions so that gusts can buy gifts or other items accordingly. The invitations can also include a direction or map with written instructions so that the venue can be found easily.
