Other mistake: At the beginning of the film, Vida and Noxema (co) win the local pageant and advance to the national level, taking ChiChi with them as a passenger. At the end of the film, ChiChi wins the national pageant for which she was not a contestant.
Suggested correction: Vida and Noxema winning the "local" contest (New York City's "Drag Queen of the Year") did not mean they "advanced" to the nationals. They simply won a paid trip to Hollywood where they could then compete in the "Miss Drag Queen of America" pageant. However, anyone could enter the pageant.
