Sorry to drag this post out of depths but I've been looking for a mod like this. Did one ever get made? If not I might take a look at making one (though I haven't ever before). If you had the underwear models wearable under clothes already then it might be simpler to add this functionality. Is it possible to catch the event of an NPC dying in Skyrim? If so and we can check the type, we could add (and hopefully equip) the items upon death. Psuedo code would be something like Catch NPC dead Event Is NPC humanoid? Yes If NPC male add male item else add female items Equip items
