This is where the wives of diplomats and millionaires and self-made women from all arenas of Parisian life arrive, discreetly, with plastic shopping bags loaded with occasionally worn couture, which Au Gré du Vent sells on consignment. Hanging enticingly in this cheerful store -- depending on that day's inventory -- might be garments from Chanel, Hermès, Prada, Gucci, Dolce & Gabbana, or Gaulthier. You won't always find the size or style you're looking for, but a woman with a sense of adventure can have a lot of fun here.
