The necessary information that needs to be included on the wedding invitations is all of the information that the guests will need to make plans to attend the wedding. This includes, the date, time, and location of the ceremony. If the reception is at a later time or different location then this information should be included as well. The full names of the bride and groom should be included so that distant relatives and family friends will be able to properly address cards and gifts. If someone other than the bride and groom is hosting the wedding, then they should be acknowledged on the wedding invitations. All of this information is imperative to include on the invitations.
In addition to providing the necessary information, the wedding invitations also need to convey the overall atmosphere of the event. This means that whether the event is casual or formal, the wedding invitations should reflect this. If the bride and groom have chosen a special theme, then this is an excellent way to incorporate it into the wedding planning. By subtly conveying the overall tone of the wedding, guests will know what to expect at the wedding and will also dress appropriately. This will save them embarrassment from wearing a gown to a casual wedding.
