This paper examines the importance of costumes in ancient Greek theatre. It explores how colors, fabrics, styles, and accessories help to convey the social status, gender, and emotions of characters. Costumes in Greek theatre are not just decorative elements; they play a crucial role in the storytelling process. By analyzing the visual language of these costumes, this study shows how costume design influences audience perception and understanding of the characters. For instance, bright colors and elaborate fabrics might indicate wealth or high social status, while simpler attire could represent lower social standing. Accessories also add layers of meaning, reflecting aspects of a character’s personality or emotional state. Understanding these visual cues helps to appreciate how Greek theatre uses costume design to enhance character development and narrative depth. This research highlights the significant role of costumes in creating a richer and more engaging theatrical experience.
