A LoRA for a goth girl, its more or less a style LoRA. Different outfits, different hair etc. You can use it to add outfits to other characters, or can be it's own character in it's own right.

Base Prompt:
G0th, Goth, Goth Girl

The rest is up to your preferences, I would recommend multicolored hair and Mascara. But be creative with your characters.
