Outer envelope
The outer envelope should take on a formal style, with full names and titles of the addressees.
Notes:
* Avoid abbreviations in the actual address (e.g., use “Boulevard” instead of “Blvd.”).
* Use Mr. and Mrs. for a married couple (followed by the husband or wive’s full name).
* Put your closest friend first if a couple is unmarried and living together.
* When inviting a widow or widower, ask them or someone close to them whether they prefer to use their full name or their married name.
* If you are inviting children to you wedding, their names do not go on the outer envelope.
Examples:
“Mr. and Mrs. Daniel Clemens
9389 Kentucky Avenue
Austin, Texas 78740”
“Mr. Alex and Mrs. Anna Descon
1103 Sumner Parkway
Hot Springs, Arkansas 73323”
“Doctor Priscilla and Raymond Miller
121 Cummings Street
Nashville, Tennessee 37849”
Inner envelope
A smaller envelope is optional, but some couples choose to do it as tradition. The smaller envelope contains the actual invitation and can be addressed with less formality.
Notes:
* If you’re inviting children (anyone under 18) to your wedding, Include their names on the inner envelope (on the second line in order of age, oldest to youngest).
* Use “Miss” for young women (young men do not have a title).
* Send children over 18 their own invitations (even if they’re living at the same address as their parents).
Example:
“Daniel and Hannah Clemens
Miss Rachel and Andrew”
“Alex and Anna Descon
Michael and Miss Gretchen”
“Doctors Priscilla and Raymond
Miss Leslie, Raymond Junior, and Miss Patricia”
