Another URGENT invite question.

For the outside envelope what if two people are living together, are married and use different last names or are significant others for a loooooong time but do not live together (I'm talking older divorced people who are boyfriend and girlfriend for 20 years and won't remarry each other or live together)?

Ahhhhh... this modern world makes invites so confusing. I should have brought my books with me.

Is it:

Mr. Gary Feldman
Ms. Christine Fleming
1 Main Street


or just

Mr. Gary Fleming

and then on the inside envelope write both names?

TIA girls

'Unmarried couples, living together can be written as Ms. Jane Doe and Mr. John Smith on one line. Or, the 'and' may be omitted by placing the second name on a separate line. The person with the closest relationship to the sender should appear first. If both persons have an equal relationship to the sender the names should be placed alphabetically by last name.'

'In the case of single females, a good rule of thumb is to use Miss for those under the age of 18 and they have never been married. Use Ms. for those who are 18 or over or are divorced or separated. Mrs. is used for those who are widowed, you may use their own first name or their husbands first name name along with her married last name, but the best rule of thumb is to try and use what the individual prefers to be called. In some circles it is preferable for a widow to use her maiden name in place of her first name and then her married name as in Mrs. Smith Doe. In the case of those who are divorced use their own first name, not the former husband's first name even though they retain their married last name, such as Mrs. Jane Doe or Ms. Jane Doe.

You may wish to extend an invitation to a single guest to bring a guest of their own. Whether you choose to or not is entirely up to you, but outside envelopes should not say 'and Guest'. This should be printed on the inside envelope. Should no inside envelope be used, and you know that a particular single guest would like to bring someone, it is advisable to take the time to find out the guest's name.'

If they are living together and married and use different last names:

Mr. John Smith and
Ms. Jane Jones
Address
City, State Zip

Mr. Smith and
Ms. Jones

If they are not living together and not married, send it to the person you know best, so if you know the guy better:

Mr. John Smith
Address
City, State Zip

on the inner, you can have both names like this (as an example):

John Smith and Jane Jones

INSIDE ENVELOPES

The guest name is placed in the center of the face side of the inner envelope. It should be written as either 'Mr. and Mrs. Jones' or 'Mr. and Mrs. Jones, Jack and Jill' (unlike the outer or mailing envelope which would be 'Mr. and Mrs. Jack Jones'). It is also acceptable to use family or first names on the inside envelopes in cases where the recipients are close friends or family (i.e. Uncle Bob and Aunt Alice, or Jennifer and Ken.) Do not include the address on the inner envelope. If you are inviting children, their names should appear on the inner envelope only and in the order of their ages, the oldest first.

The way you write the guest's name on the inner envelope generally indicates your preference for the number of people in that guest's party. If you want to invite the children, put their names on the inner envelope. Do not write 'and family' on the outer envelope. If your guests have children and their names are not on the inner envelope, it should be understood that they are not invited.

Regarding certain titles, such as members of the clergy or military ranks, see the above 'Titles' section on how to handle the inside envelope.

Singles

In the case of a single person where you are inviting them to bring a guest, the inside envelope may say 'Mary Jane and Guest' or 'Mary Jane and Escort'. If you know the name of the person's guest, it is nicer to use that, it makes people feel more welcome to see their name in print. Two single persons that reside together should be addressed 'James Jones and Jane Smith' or 'James and Jane', the person with the closest relationship to the sender should appear first. If both persons have an equal relationship to the sender the names should be placed alphabetically.

My calligraphy person has an 'addressing' section on her website that might help you as well: How to Address

Thanks girls that's what I thought but I needed confirmation.
