Write out dates

• Write out dates. 
• Regardless of the type of event you’re inviting your guests to, you should use a formal writing style on a formal invitation. This means spelling out dates and other words that are usually abbreviated.
• For example, you should write “Saturday, the nineteenth of November” instead of “Saturday, November 19th.”
• You should also write “253212 Boston Street” instead of “253212 Boston St.”

• Write out guests' full names. 
• Don’t use the shortened versions of guests’ names.

Write “Stephanie Smith”
instead of “Steph Smith" and always use last names.

• Include the hosts. 

For example, you should start a dinner invitation by saying
"Sam and Ellen Smith invite you to a dinner celebrating the graduation of their daughter Leslie from graduate school."

List the hosts in the correct order. 
Include the rest of the information

• Write out guests' full names. 
• Don’t use the shortened versions of guests’ names. Write “Stephanie Smith” instead of “Steph Smith" and always use last names.
