Outfits…

I tend to give them number of alternatives per category, based on their social rank. It's not written in stone, but nobility and very rich sims might get 5 alternative outfits at least in the everyday, formal and party categories, normally a few less in other categories. Poor households mostly get only 1-2 alternatives, and then the 2d alternative might still include a few pieces from the 1st.

I mostly did this for households that I find most interesting, though. Not all.
