Naked Sim
Have your Sim take a bath in the cheapest shower (the small square one where he or she can stand up). Once he or she is taking a shower, pause game play, and enable the move_objects on code. Delete the shower while your Sim is bathing. Resume the game and your Sim will be completely naked with no censor blur. They will think that they are in normal clothing. This effect can be disabled by "changing" clothes.
