Hello to all! I've been lurking an occasionally posting around here for a while, but I figured now's a good time to jump into making a new discussion.
We're getting ready to order invitations tonight (Yay!) and so invitation wording has come up and I'm really confused & would love some advice!
My mother believes it's proper etiquette to have all inner envelopes to people say "Jane Doe and guest" whether they are in a relationship or are just able to invite a guest. (This is besides married couples of course...)
However, from what I've seen on here, it's considered rude to not find the SO's name and put it on the invite/inner envelope (Jane Doe and John Smith).
I've googled as much as I can about the proper etiquette and have found a lot of conflicting answers (even on Emily Post AND Miss Manners).
To the two weddings I've been to recently, it was always addressed on the inner envelope as "klc09d and Guest," which never bothered me (one was my cousins wedding where she knows my Fi, then bf). Honestly, never crossed my mind it was rude.
But since I've read so much on here about it, I guess I'm asking...Is it actually against etiquette or just perceived as rude to have "Jane Doe and Guest?"
This is not a hill I will die on in argument against my mom, I'm just genuinely curious. By the way, sorry for the novel...I'm on my phone and had a hard time organizing my thoughts!

Re: And Guest or And SO's Name?
Only if you want your guests to be able to bring guests of their choice should you use "and guest." If they are in relationships, then you need to honor the relationships by listing their SOs by name. In fact, using "and guest" in those instances is very insulting to them because it suggests that they are not in recognized relationships.
Like I said, it doesn't bother me one whit to be an "and guest," but I know it bothers a lot of people. I would rather not offend my friends and family for the sake of a few less minutes FB stalking someone. And hey, if I call them or text them...I get to catch up with their lives as well! Win-win!
