HELP with...

MY STD's

So I am making my address labels for my save the dates. For the people with BF/GF I am putting both names or my friends name & guest on address label. What about people without bf/gf but are still going to invited to our wedding with a guest? Do we put & guest or just their name and then when we do wedding invites put the guest?

Thanks girls I am debating what to do and want to get these done and sent out

for the save the date i would just put the name, not the b/f g/f name too

i would wait till the invite to write 'and guest'

I think that is what I am doing- and if they are engaged. Also if we are friends with the bf/gf we are putting Ms. so and so and Mr. so so. THanks for helping me decide
