It’s questionable. Some are clearly fake. Others are factory seconds (ie. a stitch might be out of place and as such, rejected by the company for sale) others are overruns. Overruns are when a garment factory have a contract to make a certain number of items of clothing, say, 3,000 shirts. They make 3,500 to make sure that they have at least 3,000 that meet quality control. They end up with 3,300 shirts that are perfect, and sell the 3,000 to the company. That leaves 300 shirts that end up at Russian Market or wherever. If you are familiar with the brand, it’s pretty easy to tell which are real and which are fake.
