I am addressing save-the-dates and have some questions.I work with female doctors who are married. I know the Mr. always comes first, but my question is, is itMr. & Mrs. John SmithorMr. & Dr. John SmithorMr. John Smith & Dr. Jane SmithWhat about when there are different last names? Would it beMr. Christopher James & Dr. Paula Burke? Or do they go in alphabetical order. This stuff is confusing!I feel weird addressing them to the significant others of my friends and co-workers. Like, I'm friends with Jane Jones, but the invite goes to Mr. & Mrs. John Jones. Haha, I'll get over it. Have to do what's proper. TIA!
