Zara has this capability because it keeps a significant amount of its production in-house and makes sure that its own factories reserve 85 percent of their capacity for in-season adjustments. For its long-lead items, Zara uses the same foreign factories as everybody else because the costs are cheaper. But for the fast-fashion items Zara produces in-house, it often relies heavily on sophisticated fabric-sourcing, cutting, and sewing facilities nearer to its design headquarters in Spain. The wages of these European workers are higher than those of their developing-world counterparts. (Fraiman describes it as “Eight euros an hour instead of 50 cents an hour.”) But the turnaround time is miraculous: as short as two weeks from an idea in a designer’s head to a garment on a Zara store’s shelf.
