The best thing to do is make a new folder and in it put a copy of everything you normally (your avatar) has on INCLUDING skin, shape, hair and bald hair base, eyes, AO, shirt, and pants in there. Then, the next time (or maybe even this time!) you're *ruthed*, WEAR the folder. Do NOT put everything on separately as you normally would, just "wear" the folder. Right click and wear. This should fix your avi. Then you should be able to change clothes again normally. Hope this helps!
