So you've invited someone and you want them to bring their plus one. What's the proper way of addressing your debut invite? It can get a bit tricky when you don't know who their date is, but it's pretty simple when you have this guide to turn to.
Inviting a single person who'll bring a date, whom you know
Address both your guest and his/her date. Use two separate lines for addressing them on the outer envelope.
Outer envelope: Dr. Juan dela Cruz
[next line] Ms. Anna Santos
Inner envelope: Dr. dela Cruz and Ms. Santos
Inviting a single person who'll bring a date, whom you don't know
Address the invitation to that person and his/her guest. Addressing the invitation to only one person says that you are only inviting your guest, and that you'd rather s/he not bring a date. In this case, follow the rule for the inner envelope if you only have one envelope.
Outer envelope: Mr. Juan dela Cruz
Inner envelope: Mr. dela Cruz and Guest
