Costume Society of America (CSA) is a vibrant professional organization devoted to the study and preservation of dress across cultures and centuries. Since its founding in 1973, CSA has united scholars, curators, designers, collectors, and enthusiasts who explore the history, design, and cultural significance of clothing, fashion, and costume. Through national symposia, regional programming, publications like Dress, and service initiatives such as the CSA Angels Project, the Society fosters scholarship, collaboration, and public engagement. Members represent a wide range of disciplines—from museums and theaters to academia and independent research—linked by a shared passion for the artistry and meaning of dress. CSA champions rigorous research and inclusive inquiry, bringing overlooked histories to light and broadening the field’s scope.
