A rehearsal dinner is a gathering that takes place before a wedding ceremony. It usually occurs on the night before the wedding and provides an opportunity for the bride, groom, their families, and wedding party to come together in a more casual setting to celebrate the upcoming nuptials. The rehearsal dinner is often hosted by one of the couple's parents or close friends, and it serves as a chance for everyone involved in the wedding to go over the ceremony details one last time before the big day. It can also be an occasion for the bride and groom to express their gratitude to those who have helped them prepare for their special day.
