I need to head to bed so I'll stop here, but my verdict about Sandrone's model is that she's like 2023 Skirk: she's clearly playable but it's not the final version.
Her skirt is very detailed while her upper body is not, to the point where it looks like 2 different models were temporarily spliced together. Blender definitely treats it as such and refuses to apply the shader to her fat ass (pic related).
Despite having simpler textures, the lower body seems to be newer, so I expect her upper body will be adjusted when she's released. Of course it's possible she'll have a whole different outfit, but I doubt it.

TLDR: SANDY SEXO COMING SOON
