Final answer:
Without the specific literary context, it is not possible to provide an accurate response regarding what Gitl tells Hannah to wear to the wedding and Hannah's feelings about it.
Step-by-step explanation:
The original question appears to reference a passage from a work of literature where a character named Gitl instructs Hannah to wear something specific to a wedding. However, the provided reference texts do not contain any direct information about Gitl, Hannah, or a wedding scenario.
Therefore, without the context of the specific text in which Gitl and Hannah are characters, it is not possible to provide an accurate response to what Gitl tells Hannah to wear to the wedding and how Hannah feels about it.
