Hello, I can say that there are several ladies who prefer wearing saree below the navel regularly but not all. How much below, really depends upon the person, their height, willing ness, comfort zone and so on. Almost every woman would have gone down below at least more than once, knowingly or unknowingly. I would never prefer going below in open public or before elders and children. I do not like strangers touching me either. Occasionally, during special events and festivals I do sometimes prefer going up to one inch below, but even then I do not forget to maintain privacy. Going excessively low up to the pubic region makes me very uncomfortable and nervous.
