Not sure about the shoes. I read several articles and I can’t remember if the one on the law firm website said that the ruby slippers wasn’t an issue in the film since Dorothy wasn’t in it. So I don’t know if the term “ruby slippers” is trademarked so they could use “red slippers” instead. Or in typically OUaT fashion they could go with an entirely different color just to mix things up – or go with a different article of clothing . . . who knows???
At the end of the day they could choose not to have her be green at all. I mean Captain Hook doesn’t look like the Captain Hook we all think of, Little Red Riding Hood doesn’t either. There are so many twists in the show that we might never know what was done to get around copyrights or what was done because A and E had a radical idea.
Or I’m totally wrong and she is Cruella and none of this matters anyway!
