"simulacre parfait"

French to English Social Sciences Social Science, Sociology, Ethics, etc. sociology of consumption

Hello,
In an article on the sociology of fashion, I have a passing reference to (presumably) a sociologist called Lorenz who refers to fashion as a "simulacre parfait". The article then discusses Veblen's theory of conspicuous consumption. Is anyone familiar with this Lorenz and is there a traduction consacrée for the concept of "simulacre parfait"?
