The Glass Slipper Syndrome is also known as the Cinderella (In reverse) Syndrome and it only occurs with women.
Cinderella, even dressed in old rags, was a lovely and delicate girl. While her stepsisters, no matter how splendid and elegant their clothes, were still clumsy, lumpy and ugly and always would be.
Moral of the story: How hard you try... You can never put big fat, flat feet into delicate glass slippers. Your feet will always give your true self away!!
