I like that you included all of the various undressed versions! It's something I don't think I've ever seen for an outfit mod and it really adds a lot of "immersion" compared to other outfit mods where removing the "top" removes the jacket, shirt, etc. all at once. This must have been a lot of work!
You mentioned that Shino's glasses can be shift-clicked on/off; would this be possible on the outfits themselves as well (on the sleeves, shirts, pants, etc.), essentially creating an all in one version?
Also I'm curious as to why Asuna only has one version of her outfits; were there no good references for the less-clothed versions?
All in all, an excellent modpack and I hope to see more of your work! :)
