Theatrical costumes are created to meet the aesthetic and physical needs of a production, using specialized techniques and methods to achieve the custom designs created for the fantastical world of performance. The Course Series in Costume Specialties offers creative artists from any field – including theatre, fashion, textile, and visual arts – an opportunity to explore and develop creative practice in a studio setting.

The courses offer instruction and information for people interested in pursuing theatrical training part-time, costume and cosplay artists wishing to expand their skill set, and artisans wishing to gain alternative techniques and knowledge to incorporate into their own practice.

Through practical studio courses in a specific costume art or topic, you will not only survey a subject, but also gain problem-solving skills as you determine how to apply newly acquired skills and knowledge to creative projects. Classes begin with a short lecture and demonstration followed by hands-on exercises.

Those who successfully complete this course series are eligible to earn a Professional Development Award from The G. Raymond Chang School of Continuing Education.
