I am inviting my old professor/boss who I refer to as Dr. Her Last Name. I do not know her husband's name and he is not on Facebook. Would it be appropriate to address the envelope as "Dr. First Name Last Name and Husband"?
Or would it be better to just write "Mr. and Mrs. Last Name" and leave out the "Dr." But then this leaves out the formality of including first names...
The only reason I am not asking her for her husband's name outright is so that it will be a nice surprise when she gets the Save the Date in the mail.
Please let me know your thoughts! Thanks!
