I never bought those low riser jeans when they were popular. I'd go into the dept store and ask them for grown up jeans. "Sweety, I'm old enough to be your mother and no body needs to see my rolls of fat hanging out anywhere and my bottom needs to be covered all the way up to my belly button or higher-where are those jeans?"
