Looking for a mod that gives quality underwear to NPC´s

[zzaee]

I found this recently : https://www.nexusmods.com/skyrimspecialedition/mods/82790?tab=description

 

but it´s just for BHUNP , and  the author gives some instructions about how to convert them, but  I am too green yet

 

with Outfit Studio to make it ( I tried though ).
