Neither look like they are wearing, and anybody who says they can tell it's "this one" or "that one" is lying, and that will remain the case even if they try to give a hundred reasons why it's supposedly so obvious. You'd never suspect a hairpiece on either in a million years if somebody didn't tell ya first.

Do this right, and no one will ever know. And it gets easy after a while. In fact, with an experienced wearer, the only reason he may be suspected of wearing is because his hair looks better than the real hair on the other guys in the room.
