2 · Size plan
Use customer evidence before adding size depth.
The common UPILATE direction uses women’s S/M/L and covers the Chinese shoe-size 34–40 equivalent. Publish an exact S/M/L conversion only when the approved production size chart is available.
For the first order, use previous sales, booking profiles, documented unavailable-size requests or retailer records. If no local evidence exists, label the initial allocation as a test rather than a proven ratio.
