How do I properly address my invitations?

ahawke

Can someone tell me the proper way to address the invitations?
On the outside envelope and then on the inside envelope?
If I am inviting a married couple, do I use, Mr & Mrs B Douglas, Brad & Nancy Douglas, or Mr & Mrs Brad and Nancy Douglas?
What about a single or a couple with different last names?
And where do I put the "and guest" outside or inside envelope?
Starting my wedding panic!
Thanks!

Mr. and Mrs. Brad Douglas is proper for outer, inner would be Mr. and Mrs. Douglas.

different last names but married (same line and "and" to signify married)

Ms. Jane Smith and Mr. Brad Douglas (outer)
Ms. Smith and Mr. Douglas (inner)

different names and unmarried (two lines)

Ms. Jane Smith
Mr. Brad Douglas (outer)

Ms. Smith
Mr. Douglas (inner)

I would be absolutley disgusted and tempted to not attend your wedding if you addressed me as Mr. and Mrs. John Smith. I am a person and would like to be identified by my own name, not my husbands' name. However, I realize that a great number of people disagree with me on this. So you need to know your circle of people. Is your family incredibly traditional? If your family is more modern, you could go with Mr. and Mrs. Jane and John Smith or go straight to Jane and John Smith. What do you prefer? You don't necessary have to do what tradition or etiquette advises.

I grew up on a first name basis with all adults around me. No one ever demanded a Mr. or a Mrs. So I'm doing first names: Jane and John Doe.

And you don't put AND GUEST on anything.
Find out the NAMES of these guests, and use their NAMES.

Thanks for your help!
We are using guest names where applicable, but some guests don't have a certain someone in mind and in that case we need to still let them know they have the option to bring a guest!
