This replaces all clothes with Asian clothes.
It is almost always the exact same cloth ( an Ao dai and pajama) just in different colors and combinations.
Male and female are separate downloads.

I used Robert's female and male body texturing. It might also work with others, as this is showing almost no skin anyway.
If it looks bad with something like HGEC, let me know and I will work on the compatibility.

Backup: If you are not sure and want to just test this while want to keep your latest clothes, make a backup of the folders:
lowerclass, middleclass and upperclass
in data/meshes/clothes
Textures will not overwrite anything.
