The word rehearsal means the trial of a fashion show. A rehearsal is the collective practice of the choreography. In addition to the models and reserve dancers, the other parties also rehearse such as the DJ and the technical department. The aim of these rehearsals is to stage the collection perfectly. The rehearsal should develop a set routine which can ensure a smooth running of the performance. During the dress rehearsal, it is still possible to make changes or adjustments or add final touches to the choreography but by the final rehearsal (see Final Rehearsal) this will no longer be possible.
