My Sims clothes dont appear properly, they are patches of nakedness and patches of clothes except they are fully clothed when I zoom all the way in, can anyone help?

Check your graphics settings when you're in the game. Click on the ... icon (as if you're going to quit) and then click on the gear icon (two gears). What are they set to? Does it clear if up if you change it? (Let's say it's set to high, change it to medium.)

i had this problem -- try just turning down the "texture" setting first-- if this doesn't work try some of the others - like sim detail (or something like that)
