Willa Kim is an American costume designer. She began working in film and theater in the 1940s. Early in her career, she worked as an assistant to set and costume designer Raoul Pène Du Bois. The Willa Kim collection of scripts dates from 1946 to 1989. The scripts are from theater and film productions that Kim designed costumes for or considered designing costumes for, including some productions she worked on with Du Bois. The majority of scripts are for Off-Broadway or Off Off-Broadway productions. Scripts are from various stages of production, including early and later drafts. Some of the scripts have minor changes or corrections, and some contain other documents related to the production such as production schedules and brief notes addressed to Kim. The collection contains very little material documenting Kim's design process.
