Are rehearsal dinner invites necessary? Or does word of mouth suffice? We don't have a whole lot of people that aren't part of the ceremony that are still being invited to the dinner but I just know if there is certain etiquette for rehearsal dinner invites. My future in laws are doing everything for it and I doubt she knows about rehearsal invites and I hate to be the overbearing bride who is telling her she needs to send them, especially because she is forgetful/waits until the last minute and I know I'll have to bug her about it.
