What are some examples of wedding invitation envelope addressing?

Here are some clear examples to guide you. For a married couple with the same surname: 'Mr and Mrs John Smith'. For a married couple where the wife kept her surname: 'Mr John Smith and Mrs Jane Brown'. For unmarried partners: 'Mr John Smith and Ms Jane Brown', each on a separate line. For a single woman: 'Ms Emily Jones'. For a single man: 'Mr Oliver Smith'. For a family with children: 'Mr and Mrs John Smith' on the first line, then 'Emily and Oliver' on the next line, or 'and family' if you prefer. For a guest with a partner you do not know: 'Ms Emily Jones and guest'. For same-sex couples, use the same patterns: 'Mr John Smith and Mr Oliver Brown', or 'Mrs Jane Smith and Mrs Emily Jones'. If you are using inner envelopes, the outer envelope can be more formal, and the inner envelope can use first names only. Always write the address clearly, with the house number and street, then the town, county and postcode. If you are unsure about a title, it is acceptable to use the full name without a title. The most important thing is that the names are spelled correctly and the address is complete.
