The Emperor's New Clothes

In Europe several several centuries ago, a group of prisoners about to be executed are freed as part of the celebration of the upcoming marriage of the emperor's daughter, Princess Gilda, to a very rich prince from another country. Among these newly free men are an uncle-and-nephew con artist team, who continue their usual work to the point where they end up in the emperor's own palace, posing as tailors. Taking advantage of the emperor's extreme love for new and newer clothing as a symbol of his wealth, the fake tailors get him to hire them to make clothes (in time for the wedding) that are invisible to all who are either unfit for their position, or very stupid. Of course, they wouldn't make anything at all, but instead steal all of the material (many jewels) and leave the emperor and all the people thinking that they are unfit or stupid. Things start to get more difficult as neither the emperor nor Gilda like the prince she is engaged to, she and the nephew fall in love, the nephew has misgivings about being a con artist, and the emperor is constantly checking on the progress of his tailors, who are watched over by a very suspicious guard.
