The age label is not the chart identity
No. The selected tee points to SG-BOYSBMM,the hoodie to SG-GIRLSSBMM,and the jogger to SG-BOYSTROUSER in the maker’s public product data. Those are different source-guide references. A shared 13–14 Years label does not prove that every body column,garment length or endpoint is identical.
Read each selected source link
The guide reference is useful for finding the relevant current maker table;it is not a statement about who should wear the item. A teenager’s actual preferences remain separate from a retailer’s category system. We do not collect gender,body details or photographs or choose a category for a person.
Do not copy adult or overseas rows
Search results can surface M&S tables for Australia,India or other markets. Those official-domain pages still need exact market and guide-scope verification before their numbers become a UK selected-SKU reference. We do not fill an unavailable UK row from another region or an adult clothing chart.
Keep unknown mappings visible
Use the native selected chart and retain its heading,units and row label. If the exact row or garment mapping remains unverified,the local finder says unknown. It does not average two categories or interpolate between adjacent sizes. Current received labels and independent content/textile review remain pending.
Apply it to the selected purchase
When a chart route changes from boys body measurements to girls body measurements, stop treating the two pages as one continuous size scale. The selected product link determines which source is relevant.
