SHEIN

SHEIN is a cross-border fast-fashion retailer whose defining capability is product turnover: it introduces new items continuously in small initial batches and scales production only on what sells.

That test-and-repeat model, run against real-time demand data, is why its catalogue is far larger and faster-moving than conventional fashion retail, where seasonal ranges are committed months in advance.

The approach has drawn scrutiny over labour conditions, environmental impact and design originality — considerations worth being aware of independently of the pricing.
