Yes, that's exactly the gap I'm talking about. If I didn't have any underwear on, it would be like where's my toolbox because I'm a plumber now. And if it's true they are supposed to be worn at the hip, well then, the crotch is down between my thighs and I have to keep forcing my pants lower because they won't stay there. So I have to either wear a belt with all my pants to force the gap closed or else I will sew some elastic in there. I don't often do that, but it has worked wonders when I've done it. You have to rip some threads out of the waist band's seam and then put a strip of elastic inside. Sew one end down, then stretch it far, pin it in place and sew the other end down. Then replace the ripped out threads on the waist band. Now you can't even see what was done.
