Man, when you think about it, you don't even see those pinched waistlines on Mad Men as much anymore. The female characters have all sort of moved into the era of the mod shift dress (Betty and her muu-muus being the most extreme example). Maybe it's because they gained weight from all the chores they don't do anymore! Ahhhh! Women's waistlines have reportedly grown six inches since the 1950s, before there were space-agey $200 Shark Navigator Vaccuums to buy in order to simplify the gruntwork of chores.
