As mentioned in some other reviews, these do roll over after you sit and then get up.  It is a bummer because the panties feel good but I just don't want to be tugging my pants up when I am wearing a dress.  With slacks or jeans they are fine, but not a dress. I am not by any means heavy but do have a teeny pooch that I'd like to rein in when wearing a dress, but these just don't do it.
