Etiquette lessons: Wedding invitations

Entire chapters have been written on the intricacies of invitation phrasing, so if your situation is atypical or you have a specific question, be sure to do some additional research. The below information should work for most traditional family dynamics. 

If your parents are paying: 
“Timothy and Jeanne Smith request the honour of your presence* at the marriage of their daughter Rachel Smith to Andrew McCall.”

If you are paying: 
“Rachel Smith and Andrew McCall, along with their parents, Timothy and Jeanne Smith and Gregory and Rebecca McCall, request the pleasure of your company* at their marriage.”

*Note: “Request the honour of your presence” (with the British spelling) indicates a church ceremony. “Request the pleasure of your company” is appropriate for ceremonies held anywhere else.
