Im new at this, remember that.Heres what you do:

1:create new family under FREEPLAY mode.
2:move in and buy pathlogine costume trunk.
3:walk up to it and choose WEAR NOTHING, ROBOT SUIT, or whatever you want.
4:pause and choose QUIT.save before you quit!
5:evict your family and edit them.they should still be in their same clothes, so the cheat SHOULD NOT have worked.
6:calm down, itll work.if it worked the first time, good for you.
7:repeat steps 1 through 5.NOW they should be naked with just a patch in 'places' or in a robot, yeti, or whatever suit you chose.
When you finish, you can edit them. If you make a sim naked, don't put pants on them or it will ruin it. There are some tatoos that go beyond the points you can normally see them. Some of them are VERY sexy, for guys and girls! This cheat is perfect if you want to make a guy and girl do stuff all night long!

P.S. This cheat will wear off if you do something that involves changing clothes. Example: going to bed, working out, getting a shower, etc.

Happy cheating!

You know when your sim is to cranky to study well here is a helpful hint.First kill your sim any way(fire,hand stuck in slot machin).Then go to the grim reaper go to fiddle changle when you do prees the Z button right after your sim pulls out the fiddle and it will do the changle for you.Now when your sim is to cranky to study agin go to your own tomb stone and dance at it a couple times and your sim catch on fire and you do the stuf agin.Also whaen your dead look at your goals you will have eazy ones that give you a lot of points like spook a sim 500 points come back to life 175 points.Plaese if you have the time rate this cheat.
