I get the going completely commando part. In guy mode, I'm the same way. I'm just curious as to whether my wife's wearing both panties _AND_ pantyhose is the norm or part of her conservative upbringing. Do all moms tell their daughters that they should wear panties with pantyhose, or is that just the peculiarity of my MiL?
As to the effectiveness of just wearing pantyhose, I've found that I have better luck avoiding seam lines and unsightly bulges without panties. That may just be my anatomy and build talking, though...
