SHEIN has a small run just in time manufacturing model. They carry less than a day of inventory of many items and consolidate and airmail from warehouses next to their Chinese factories. H&M and Zara cannot compete. They order three months ahead, have six months of stock sitting on slow sea freight or in stores, and discard a massive amount of clothing from their stores at the end of season.
