This slipup can be found during the scene where Hannah is standing under the covered doorway of a drugstore when it is raining. The college student (forgot his name at the moment)is talking to her and then buys the umbrella for her to walk under. This slip comes before the "Fella with an Umbrella" song.

When Hannah is under the covered doorway, she has no earings, when she is walking under the umbrella, she has large, black, circular earings. Pretty big mistake if you ask me.
