By 2019, Cho had designed costumes for more than 200 productions. Her designs have been seen in productions on
Broadway,
off-Broadway, in U.S. regional theatres, Canada, Britain (including
Royal Shakespeare Company) and Asia. In addition to plays and musicals, she has designed for opera companies, including the
Metropolitan Opera and dance companies, including
American Ballet Theatre. Before beginning design work on historical projects, Cho researches the era and collects image inspiration from catalogs, paintings, and books. She has called this research her favorite part of the design process. However, Cho does allow herself some liberties when it comes to historical accuracy. In her work for Anastasia, for example, the Parisian costumes "[have] a heightened flair; it’s not true 1920s," as she instead wanted to invoke "a playful, pushed, bright feeling, like a young lady’s fantasy of what Paris is, a romanticized view, to have an opposite effect of the Russian revolution costumes". In other cases, her costumes stray from historical accuracy to allow dancers to perform "non-period movement", to appeal to the modern gaze, or to allow for quick changes backstage. When picking fabrics for her designs, she prefers to choose all the fabric for the production at one time; "I can’t design one gown in isolation". == Personal life ==
