Enable the boolProp testingCheatsEnabled true code. Then, hold [Shift] and click on a teen Sim. Select the tab that reads "Change Suit". Change into maternity clothes and your Sim will walk around naked. Note: They can go to public lots like this, but they will change into their normal or work outfits when they go to school or work. Note: Even if the censorgridsize 0 is off, there will be no pixels.
