Here’s Every Single Way to Address Wedding Invitation Envelopes
Married Couples With The Same Last Name
The formal presentation typically uses the husband’s full name…but if that irks you, listing the husband and wife’s full names (husband first) is also Granny-approved.
Married Couples With Different Last Names
Spell out both full names—ladies first!
Married Same Sex Couples
Whether the couple has the same last name or not, alphabetical order is the preferred presentation.
Per tradition, names should be listed on separate lines, alphabetically. (But if you'd prefer to write "Mr. X and Mrs. Y" on the same line, you really shouldn't ruffle any feathers.)
The doctor designation should always be written in full—and first in line. (P.S. For a brainiac doctor couple, “The Doctors Smith” can be used, and if they have different last names, alphabetical order is the rule of thumb.)
Families With Children
Parents should be addressed on their own line first, per the guidelines above and children can be listed on a separate line below, by just their first names, in age-descending order. Prefer a more casual approach? "The Smith Family" is totally fine too.
Mr. does the trick.
And repeat for Ms.
Gendered pronouns can be exhausting for friends and family who don’t subscribe to them. In that case, ditch the formality of titles entirely and simply use their full name.
The best way to extend an invitation to a single pal’s guest is to send a personal invite to the date’s home address. However, adding a “+ Guest” to your friend's invitation is fine in a time crunch.
