plus one

You would only address the invitation to them. If you have an RSVP card you can put we have reserved 1 seat in your honor or put ___ of 1 attending.

THANK YOU.......I have been going over this a million times trying to figure out what to say.

To anyone that was single, we addressed the invite to just them (and the save the date). Then the RSVP said "___ out of ____ attending" and we filled out the second line with a "1".

I usually just address it to them. If I want someone to have a plus one I usually say so. But some people have this thing where they think just because it isn't explicitly said that they can't not bring a plus one must mean they can -_- so I would also do what PP said where you say we have reserved __ seats for you.

You address it only to them by name and put "We have reserved 1 seat in your honor" on the rsvp card. No need for individual extra correspondence. I put a FAQ about plus one's on my wedding website.

Traditionally, an invitation addressed to only 1 person means no plus one. If you are inviting someone with a plus one you would either put the name of the plus one (if you know who it would be) or would say "Mr/Ms ____ and guest" which would mean they could bring any person they like
