oh sorry about the bumping
for the under, after searching on google, i found that sarashi fits with a modern pants like
this pantswell, it's not changing geometry, it's just a bandage bra that cover from upper chest to lower chest
for the addition of the clothes like the image, no, you don't have to add it, it's just a sarashi with some pants (I love simple)
and for the texture bandage, try to look at this
Dressit has sarashi attached on the chest part, but when I try to edit it with nifskope (remove the dress, ties and well almost everything but sarashi), it's was not a real full sarashi, it's just half on the back, and a hole at the front, I would try to make it, if I knew how to mess up with blender, that's why I request in here
btw, I like the bandage pants, just need to find a good texture on it, and it's good

i'll try to lookup on the bandage texture.

thanks for the kind reply. much appreciated.
