Grace Mirabella's famous caption of Lacroix which pretty much applies to Valli as well. Only I think he is the one who has fallen out of step with the what fashion is about right now.:
I always felt that Lacroix's was a profoundly anti-woman moment. So it amazed me to see how avidly women fell for his clothes. They fell in droves, sometimes at $45,000 a pop. I'd see them all turned out at the Metropolitan Museum of Art's Costume Institute ball wearing his costumes -- or other similar confections by Ungaro or Scaasi -- and I remember thinking how absolutely tortured they looked. And often they were tortured: Their crinolines didn't permit them to sit down and they had to turn sideways to fit through doorways. When I saw this, and I saw the glee with which so many women swallowed it up, I realized that it wasn't Lacroix, it was I who was falling out of step. Lacroix's success told me that there was something widespread going on in society and that his clothes were just the tip of the iceberg. It told me, very clearly, what these women, flaunting their froufrou, were really all about: wealth and display and excess. And in that, they weren't unlike everyone else in New York in the 1980s.
