Theatrical costumes are clothing and accessories worn by actors during performances to help portray their characters. These costumes can range from historical outfits to fantastical designs, depending on the play or production. They play a crucial role in storytelling by visually representing the time period, setting, and personality of the characters. Costumes are often created by costume designers, who work closely with directors to ensure that the attire aligns with the overall vision of the production. Materials used can vary widely, from luxurious fabrics to everyday clothing, and may include items like hats, masks, and jewelry to enhance the character's appearance.
