I have been trying to figure out if putting "and guest" will come across as inappropriate on the outer envelops for me invitations and I have read a lot of mixed reviews on the matter.
I know that if a friend in a relationship, both names should be included. On my guest list there is quite a few single people on the guest list that are not currently seeing anyone, but I would still like to give them an option to bring a date.
All of my RSVP cards have a place to fill in the number of guests that will be attending per party. Is that enough to let people know that it's an option to bring a guest or should I make sure to clarify by putting "and guest" on the envelope to let people know they can bring someone along.
If it helps at all, the wedding is going to be a cocktail reception, so more of a semi-formal event rather than strictly formal. The invitations reinfect that theme as well. I'm not sure if that makes a difference, but figured it couldn't hurt to clarify.
