I posted originally in May of last year. I am posting again hoping to find the answer.  This is an old movie, maybe the 60’s or early 70’s.  A woman is married to a cop, he thinks she is cheating on him so he starts investigating, following her etc. One scene that stands out is where he confronts her and says she went out and had pantyhose on with a run on her right leg and when she came home the run was on the left leg (or vice versa) she explained that she was in the ladies room, a little boy threw up on her, she took the pantyhose off, washed them in the sink then when she put them back on she put them on inside out or something which put the run on the opposite leg.  I have never seen it again and have no clue who was in it. I believe it was in Black and white.  I would appreciate any help. Thank you!
