It looks like you are wearing an alpha mask for some shorts/pants. Look in your worn items and look for a checked white little shirt icon. Right click on it and choose "detach from myself". If I guessed right here, you will be back to your glorious naked self in seconds! (oh, don't get me wrong, I'm not asking for a picture when you are fixed!!! )

LOL! Thanks for this clarification!!! (*shakes head in disappointment*)

It happens very often in crowded places due to heavy lag. People randomly appear half transparent or half naked, or with their hair and clothes flying beside them in the air. If this is your issue, there is not much you can do... 

If the problem happens even in an almost empty area, you could have a texture cache issue. Try clearing your cache within the viewer under "preferences", quit and relog.

If the lattest still doesn't help, you may consider clearing your cache outside SL. The following instructions were written by the Firestorm team but apply to all viewers.
