Theatrical costume

One of the more prominent places people see costumes is in theatre, film and on television. In combination with other aspects, theatrical costumes can help actors portray characters' age, gender role, profession, social class, personality, and even information about the historical period/era, geographic location and time of day, as well as the season or weather of the theatrical performance. Often, stylized theatrical costumes can exaggerate some aspect of a character; for example Harlequin and Pantaloon in the Commedia dell'Arte.
