Definition & Meaning of "dress rehearsal"

What is a "dress rehearsal"?

A dress rehearsal is a full run-through of a theatrical performance or live show where all elements, including costumes, makeup, and props, are used as they would be in the actual performance. This final rehearsal allows the cast and crew to practice the entire show in its complete form, ensuring that everything is synchronized and functioning correctly. It helps identify any last-minute issues with timing, technical aspects, or staging, providing an opportunity to make adjustments before the performance is presented to an audience.
