Some outfits work some don't

[huhyeahso]

Some outfits work on my character (obi elven assassin for example https://www.nexusmods.com/skyrimspecialedition/mods/152714 ) but some outfitswill have my characters body transparent and the outfit doesn't show up ( elle dark assassin for example https://www.nexusmods.com/skyrimspecialedition/mods/153943 ). Both are built in bodyslide.

What could i be missing? I'm pretty sure i built everything available in bodyslide did i forget an "outfit body" or something.

You have another thing equipped that occupies mesh partition 32 while not occupying equipment slot 32 - visually hides the body while still allowing both items to be equipped at the same time. I think the most typical cause of this is DD. SOS causes something similar too occasionally but it might be limited to slot/partition 49 and/or 52; been too long since I saw that, I forget the details.
