It's important to use the proper wedding invitation wording when requesting guests' attendance at a reception-only celebration. Make some small tweaks to the wedding invitation copy, such as replacing "request the honor of your presence at the wedding of" with "request the honor of your presence to celebrate the wedding of." If you've already held the ceremony, the invites can double as wedding announcements. Feel free to add a line at the top stating that you've tied the knot, followed by a request to attend the reception.
