I bought these when I was 8 months pregnant.  I had gotten to the point where dresses were the only comfortable option.  I bought these because like everyone else that buys them, my thigh rub and chaff.  I wear them at least twice a week.  they stretch over my enormous belly perfectly!!! They are not tight so they do not leave marks or lines.  I love them and plan to get a few more pair in other colors.
