Authorial Concepts of Stage Costume in Contemporary Theatre: From Historical Determinism to Experimental Interpretation

This article examines the evolution of authorial concepts in stage costume design within contemporary theatre, focusing on the transition from historically determined visual systems to experimental and conceptual approaches. The study explores how stage costume functions not merely as a decorative or illustrative element, but as an autonomous semiotic structure that actively participates in the construction of theatrical meaning. Drawing upon historical analysis, theoretical models of theatrical aesthetics, and contemporary design practices, the research identifies key shifts in the understanding of authorship, symbolism, and performative functionality of costume. The article argues that modern stage costume design increasingly reflects the personal worldview of the costume designer, positioning authorship as a central creative force alongside the director and playwright. By applying an IMRAD-based methodological framework, the study contributes to theatre studies, scenography, and costume design theory, offering a systematic academic interpretation relevant to current theatrical practices and scholarly discourse.
