In my opinion "Downward Flow Theory" is still applicable in fashion. Those in the lower rungs of society have always wanted to look more affluent in an attempt to be more socially acceptable. I think "downward flow" is most greatly illustrated with Dior's 1947 "New Look". This dramatic change in style after WWII at first only touched those with access to Dior, but by the late 40's and early 50's the "New Look" shilouette was everywhere. Everyone from Lucille Ball on "I Love Lucy" to the Queen at Ascot and Mothers the world over, wore the "New Look".
