how do you delete/remove a sim from the game?

That's OLD WAY TO REMOVE THEM it no longer goes thru wardrobe.

Have the sim free not doing nothing that you want to delete.

Click on sim.

You will see menu says total makeover for 12 LP ( this is how you change a name now BTW.) And have birthday. AT THE TOP where it shows sims name look to the end on right for a red X AND THATS WHERE U DELETE THAT SIM.
