PIKOBUY Size Choice Before QC

Why this page is separate

This page is only about choosing a size before QC, not judging all QC mistakes. The buyer has not approved the warehouse item yet. The important job is to decide whether the selected option is likely to match the body measurement, shoe length, garment width or accessory dimension that the buyer actually needs.

A good size row includes the seller chart, the buyer reference measurement, the chosen option name and the exact photo or warehouse measurement that should be requested later. If those four items are not aligned, the buyer should not pay just because the product image looks correct.

The most common failure is mixing category logic. Hoodie sizing depends on chest, shoulder and sleeve; shoe sizing depends on outsole or insole; pants depend on waist and length. One general size note cannot cover every category. The row should say which measurement matters for this item.

Use this page before the QC page. The output should be a measurement request, a safer size choice, a second source to compare, or a decision to skip the product before warehouse time is wasted.

Decision rules

• Reference item
  Compare against a product the buyer already owns, not a random chart.
• Selected option
  Write the exact size or variant that will be ordered.
• Measurement proof
  Decide which warehouse measurement should confirm the choice.
• Risk result
  Choose, measure, compare another source or skip before payment.

Size proof checklist

Before payment, write the exact reference measurement in the row. For clothing, compare chest width, shoulder width, sleeve length and total length. For shoes, compare outsole or insole length with the size conversion shown by the seller. For accessories, confirm the measurement that changes fit or usability.

If the buyer cannot name the measurement that matters, QC will not solve the problem later. A warehouse photo can confirm a tag or tape measure, but it cannot guess the fit the buyer wanted. This page should therefore create a size note before the item becomes a warehouse decision.

Buyer example

Example: a buyer wants a hoodie with a relaxed fit, but the seller chart uses Asian sizing and the product photos do not show a tape measure. The row should not say only size L. It should record the target chest width, expected length, selected seller size and whether the buyer wants a loose or regular fit. If the seller chart is missing, compare another listing before payment.

This page is useful because the wrong size is usually discovered too late. Once the item reaches warehouse, the buyer can request measurements, but the exchange may still cost time. A size choice made before QC protects the order from avoidable returns and keeps the final parcel cleaner.
