I had been googling and looked up on the Q&A but not finding this direct answer.
If I am inviting a couple and I only know the wife does her name go first or go by the standard Mr. and Mrs His full name....
This is the last thing I need to confirm before I address the STD's and don't want to go wrong even though half the websites I found said there is no rule for STDS like there are for invites
Also throw this in here, did you put & Guest on the STDS or leave that off? We offer Pre-RSVP online due to so many people booking their travel plans this Summer for the wedding or already took it off when our families told them. If they have a guest the guests name is needed on the online rsvp
