Addressing Save the Dates & Invitations

So for the invitation:

The outside envelope is addressed to the person you know, or the head of the household, or married couple. The inner envelope specifically states all people included with that invitation. This includes children or spouses or a plus one.

Example: Outside: Mr. and Mrs. Bob and Betty Jones

Inside: Bob, Bettey, Sarah, and Andrew Jones

OR

A colleague example: Outside - Mr. Andrew Smith

Inside: Andrew Smith and Guest (or name of spouse or significant other if you know it)

I didn't include any +1's on the save the dates

I wasn't so fancy. For the STD's I just wrote James & Ann Smith.

For the invite, I wrote on the envelope (just had 1 - no innie and outtie) Mr & Mrs James Smith

But on the RSVP card I wrote out everyone's name who was invited and how many seats I reserved for them

Adding plus ones is up to you. On the invitation envelope I just wrote Jane Doe.

On the RSVP card I wrote I reserved 2 seats for her and listed Jane Doe & Guest

For the save the date, I was less formal, like Out the Window, and didn't include if they were allowed a guest.

For invitations, which I am also currently working on, I am being a little more formal, but only including one envelope, so I put Mr. & Mrs. Robert Smith & Family. If they are not married, but living together, I addressed each one on a seperate line. I am not putting "& guest" on the envelope, simply because I don't feel inclined to have all of our single friends feel they need to bring a date either. If they choose to bring one, I have accounted for that in the numbers, so I won't be totally shocked.

I was less formal on the save the days. On the invitations I put Mr. and Mrs. John Smith and family. We didn't have an inner envelope.

This is what I did, but I am not an etiquette guru.

For family: Mr./Mrs. John Smith & Family

For non-married couples: Mr. John Smith & Ms. Jane Doe

For singles that get a +1: Mr. John Smith & Guest

Invitations:

From my understanding, the use of "and" is only for married couples. For unmarried couples you would put them on 2 separate lines:

Mr. John Smith

Ms. Pocohantas Princess

Married:

Mr. & Mrs. John Smith (traditional) or Mr. John smith & Doctor Princess

Child A

Child B

You don't have to invite a guest for all of your singles out there. Just make a decision and be firm and stick with it. We're only inviting a +1 if we know the other person or if they live together.

Save the dates are less formal - only send them to the people you know FOR SURE will be invited. If you're shaky on the +1 situation, I'd leave them out on the STD.
