SOS revealing clothes modding problem

[Aliu]

HI guys,

I am trying to complete the (revealing armor for sos) mod (for inappropriate purpose )

by importing malebody_0/1.nif into clothes nif with BodySlide and Outfit Studio

malebody_0/1.nif are from the XP32MSE skeleton 

 

Frist problem is that ,it will leave a gap between sos pelvis and the body pelvis

 

 

like the sos addon is not at the right place

 

 

Second, I need to make the newly edited armor/clothes revealing on default

how do I do that?Do I have to make a bsa?

 

Thanks for your help, it's my first post 

excuse me ,if I make any mistake ty
