This being an 1960s DC comics the downgrade themes are obviously very light and reminded me slightly of British girl comics from the same period that featured numerous stories of lady/maid swaps (all ending happily, of course).
In this particular comic book, Superman agrees to tell Lois his real identity only if she completed a challenge: they will travel to three time periods and in each one Superman will disguise as someone. If Lois Lane guesses who he is, he will reveal his identity to her. In one of the time periods Lois finds herself as Cinderella. Superman tears up her clothes and puts her with a step mother who punishes her for having run away. Needless to say, her step sisters appear shortly to tease her. Like in the original fairytale, she eventually goes to the ball but at midnight her gown turns into rags (see scans below).
