Silk sale inventory is not current season (in fact this upcoming one is from Fall 2012 and older) unless deemed defective (you have to inspect closely, especially cashmere or summer twill GM), so the sale does not impact the regular inventory. Remember the sale items are items that were not sold during the past two years or older, so it's reasonable to expect colorways that are too horrid that nobody bothered. Those asides, there are other beautiful items and are great finds.
There is no leather goods nor bags, so the sale is also not impacting the inventory at the stores. Most sale items were already marked S and set aside from the sale from a bit ago as well.
The sale is at the conference center named Palais de Congres (almost near the suburb of Paris, Neuilly sur Seine/La Defense), not at H stores.
Thank you so much for the helpful explanation! I guess I was also wondering if anyone had noticed that the regular inventory was more depleted simply because there are so many H fans in Paris attending the sale who also stop by the store to shop regular inventory. Maybe it's not the same crowd?
