Start with the overall shape
Compare the front, back, both sides, and top view. Look for obvious asymmetry, warped panels, uneven sole shape, or a silhouette that changes from one side to the other. Camera angle can distort proportions, so avoid judging from a single frame.
Scan the surface under consistent light
Check color consistency, scratches, stains, dents, glue marks, pulled threads, and fabric flaws. Warehouse lighting and automatic camera processing can shift color; treat a shade mismatch as a reason to ask for clarification, not instant proof of a defect.
Zoom in on repeated details
Compare left and right stitching, print placement, embroidery, eyelets, zippers, hardware, and label alignment. Repeated elements make uneven spacing easier to spot.
Use size cues carefully
Read the photographed size tag and any ruler or measurement photo. A labeled size does not guarantee fit. Compare the actual measurements with an item you own, and check the destination agent’s current options if a measurement is missing.
What QC photos cannot prove
If the source page does not show a QC marker, this catalog does not add one. If it does show QC evidence, the product page labels that limited fact without calling the item verified or authentic.
