A recessional is when the wedding party walks back up the aisle at the conclusion of the wedding ceremony. You may think that the order is the same as the processional, but that's not necessarily true. Typically, the newly married couple lead the way, followed by the bridesmaids, groomsmens, ring bearers and flower girls, and the officiant. If the bridesmaids and groomsmen were paired up for the processional, they typically also exit as pairs.
Once the bridal party has finished exiting the ceremony space, then the immediate family leads the congregation in exiting.
Often, there is a triumphant and joyous piece of music playing during the recessional. If the music ends before the congregation is finished, a more subdued but still joyous piece can be played to conclude the recessional. Wedding Ceremony Music
