Ecommerce Size Guide Generator — illustrative example

INPUT
Shirt size M: chest garment width 52 cm laid flat.

RESULT
Label 52 cm as garment width, not body circumference; include the supplier's measurement method and fit guidance if available.

REVIEW
Size guides should use verified measurements and clear units. Distinguish body measurements from product measurements and explain the intended fit.

This is a teaching example, not a live execution record.
