I was talking with my friend last night who is starting to receive her RSVP's back. She is having a smallish wedding (55 guests invited and 45ish coming). It is just family and close friends. She invited Mr. and Mrs. X to the wedding. Mr. X can't come and Mrs. X has invited a friend to be her plus one. No one knows the guest Mrs. X is planning to bring. Mrs. X does have several other friends attending the wedding so she will have friends to talk to and sit with. Is this ok to substitute your husband for a stranger? If Mrs. X didn't know anyone else, I would say 100% yes it's ok. Even if it was a big wedding it might not be odd. But it is a small wedding. How does this work?
When she asked I wasn't sure what the etiquette was for this. I am now curious, so I know when we send out our invites.
