This is a fairly extensive model
She has 14 eyes textures, 2 body textures (vampire, cured), 4 outfits with multiple textures for each, and some extra stuff (coffin, elder scroll etc.).
For the mermaid dress, you'll have to hide the legs inside the dress manually. I did this to keep the dress shape intact and it's not supposed to stretch anyway. There are bones on the cloth bone layer to control the "tail".
