Can we get rid of the randomly generated outfits on Sims that aren't part of their outfit list?

I cannot stand that this happens with the outfits, but I also cannot stand the weird random NPCs that the game makes on it's own. This basically ruined the Uni pack for me, because I put hours of extra work with MCCC to make all the roommates look less freaky, only to have them be replaced by more random freak roommates the next semester. It's stuff like this that has kept me from touching the game even though I have been off of work for a couple months now. Shame really.
