Was trying to figure out how I could get werewolf sims to wear these custom meshes when they transform https://modthesims.info/showthread....00&goto=newpost seemlingly to no luck. In speculating how this might be made possible I came to this idea of a custom outfit category (e.g. Everyday, Active, Formal OR work uniform, etc.) that sims instantaneously change into when they transform.

Bouncing off this, I went searching for mods that affect clothing categories in any particular way, I couldn't find any at all. Which made me wonder if creating mods that expand the number of outfit categories, or even just enabling multiple variations of each category, was technically unfeasible because of the way these were implemented. Of course Maxis themselves added new categories through EPs. This just made me even more curious to know how they work in general.
