I ran into this problem recently and thought I would bring some clarification to the matter. Is it okay to request money on your invitations? ABSOLUTELY NOT! There are printers who will tell you that it is okay to put “Wishing Well Wedding” or “Wishing Well Reception” on your invitations. There are even “wedding” website that have special wording or “scripts” for couples to use.
Although someone has come up with some creative way to ask for gifts, money, or charitable donations, you NEVER mention gifts of any kind on your invitations or announcements, or even send with the invitation; to do so imply that a guest is required to give you a present. Some guests will actually be appalled by this. A wedding invitation should simply convey that you would like someone to be there and partake this very special occasion.
The next question –
How do you let your guests know? Most guests will ask your immediate family, close friends or a member of the Bridal Party for your registry information. The response should be based on each individuals comfort level. They could simply state, “They have all the essential household items, so they do not have a gift registry" or if they are comfortable with the individual asking, they could go into more detail.
As I mentioned before, some feel that it’s fine to include this information on your invitations, stating that times have changed. Keep in mind that people come up with reasons to do and say things and others tend to follow suit, but that does not mean that it is the right thing to do. In the end the choice is yours. Remember that your wedding from the invitations to the reception should be a reflection of you.
