Measure the actual garment flat and record the points a buyer needs, such as chest, length, waist, or inseam. State the unit and whether the figure is garment width or body measurement; do not assume a maker's size label matches another brand.
Photograph the tape at each measurement point and use the same method for every piece. Note stretch, alterations, or unusual cuts that affect fit. For trousers, distinguish waist and inseam; for tops, show chest width and overall length.
A measurement helps comparison but cannot guarantee fit. Keep the maker's label visible where possible, and invite the buyer to compare the figures with a garment they already own. If a label is missing, say so and rely on measured details rather than guessing a standard size. Compare these figures with the garment itself rather than relying on a generic chart.
