Costumers at Work: The Collaborative Creativity, Emotional Labour, and Technical Skill of Costume Creation explores the various forms of work carried out in the costume workshop by the myriads of skilled professionals who transform ideas and sketches into the wearable costumes seen on stage. Costume work, as collective, collaborative, and material labour produced by a predominantly female workforce, has been long overlooked by the performance industry and those who study it.This book exposes the inherent tensions between theatre’s strict hierarchies and collaborative ideology and how these inform the structures negotiated day to day by costumers as they carry out their work.Through close attention to their work, the book establishes costumers’ work as collaborative and complex, a creative and emotional labour that contributes to enhanced storytelling, actor performance, and audience experience.Using extensive ethnographic observation conducted over 14 months at three professional theatre costume workshops around Australia, combined with extant interviews and research from across the globe, Costumers at Work provides explicit theories and guidance about the behaviours, skills, and communication modes that make costume collaboration more effective and enjoyable. This book is written for costume researchers, practitioners, and students of theatrical costume design and construction, along with theatre scholars broadly.
