For many years I did the "mexican carry", tucked inside the waist band of my pants in the back of my right hip. That worked well for revolver and the light Glock. The heavy Colt Officers Model tended to pull the belt down a bit and print. I have also used the fanny pack and like to use a small one that is not so obviously a holster. I do have a waist band style elastic band that is useful but uncomfortable in the summer. Inside the waistband holsters are ok but only it they have a clip to hold onto the belt otherwise they tend to come out with the gun, That can be embarrassing. A levi jacket has inside pockets that can be easily modified with a needle and thread to make a passable holster. The older and "softer" the denim the more it tends to show the piece.
More often than not I'll use the fanny pack or inside waistband as those are the two methods I have used the most and am comfortable with.
I have not found an outside the waistband holster that comes close to being concealable in everyday clothes. Even with a suit coat it shows. Under a heavy winter coat it's no big deal, until you take the coat off then it's out in the open, defeating the purpose of hiding it to begin with. If I am ccw I want it hidden, not visible to casual observation other wise it's just an open carry anyhow.
