Isn't it probably true that a goodly number of people who are willing to pay exorbitant prices are ones who are happy to show off or confirm that they can afford to wear these items (or are smart enough to find them discounted and can appear to afford them)? There are plenty of high quality and predictably expensive items that don't reveal the maker with their logos; people who don't want to advertise but want quality can find it, I contend.
