The "visible from three sides requirement" is an urban myth. It does not exist ANYWHERE in law, statute, code or ordinance.
It is an "interpretation" published by the Attorney General, but it is NOT the AG's own interpretation. It comes from the fevered minds of some rogue WV State Troopers--who have no authority or legal right to establish legal interpretations.
Open Carry is any form of carry that does not attempt to conceal the true nature or location of a firearm. On your hip, in a holster, in plain view, without any clothing obscuring it is Open Carry, regardless of which side of your body the cop who is looking at you is on.
If there were any legal authority to the "visible from three sides" argument, the ONLY place you could legally OC in West Virginia would be on top of your head, which is absurd...
Carry in a holster, on your hip, and just be SURE that your clothing does not every, in any way, obscure or even partially cover your gun.
Or, you could get a CC permit, and then it doesn't matter how or where you carry your firearm on your body...
AS far as CCing, there is no statute that prohibits "printing" in WV, so as long as you are making a reasonable attempt to conceal, and have a permit, you are OK. Just don't be stupid.
Wear appropriate clothing. Get a quality CC holster that fits your gun AND your body and is comfortable. Wear appropriate cover clothing--loose shirts, a jacket, etc. And if you are going to carry IWB, buy pants that are one size too big, or else it won't be comfortable, and your pants won't fit right and will look weird.
Look at yourself in a mirror. Have a friend look at you. IF you can INSTANTLY tell you are CCing, you're doing it wrong.
It really IS that simple...
