How should a formal invitation be worded?

Formal invitation wording follows a fixed, top-to-bottom structure. Use full names, spell out dates and times, and avoid abbreviations.

• Host line (who is inviting).
• Request line.
• Event name.
• Date and time, spelled out.
• Venue.
• Reply instructions.

For less formal events you can loosen this structure and add personality while keeping the details clear.
