ChatGPT AI Guide: Create a Shirt Chart-Discrepancy Packet

Use the chat to organise a possible chart discrepancy before writing a complaint or deciding what caused it. The output should preserve the exact item, source chart, reading method and repeated values. This is different from asking whether the shirt is wrong from a photograph. A useful packet makes the comparison understandable to another person while keeping policy questions and personal fit preference separate.

Prepare the input worksheet

Copy the relevant observations into a small labelled record before prompting. Keep source facts separate from your preferences and requested changes. Replace missing values with unknown rather than inviting the assistant to complete them from general knowledge.

• Exact ordered and received variant
• Saved chart source
• Repeated measurements with routes and units

Fictional input: the ordered and received variant identifiers match. The saved chart says 55 cm flat chest; two readings using the stated route show 53 cm. The store's acceptable tolerance and assessment procedure have not been supplied.

Copyable master prompt

Turn these shirt measurements and chart notes into a factual comparison. Verify that item, variant, unit and route match. Keep repeated readings and missing method information visible. Do not invent manufacturing tolerances, refund rights or a cause for the mismatch. Draft one concise question for the seller using only confirmed observations. Return exact item/variant, chart source, route/unit, repeat readings and unresolved method questions. Draft one neutral seller question; do not invent a tolerance, cause or remedy. Use only the worksheet supplied below. Keep unknowns visible and do not add product specifications, prices, measurements or policies that are absent from it.

Filled fictional worked example

The following response is an illustrative teaching example. It is not a model test, a TryBuy product measurement or a claim that the assistant verified the physical garment.

The fictional response can report a numerical difference without concluding that a manufacturing fault or return entitlement exists. Those are separate claims. If the assistant sounds more certain than the record, ask it to remove the cause and retain the observation. Your eventual action should follow actual information from the seller.

Follow-up revision prompts

Use one focused correction at a time. Paste the relevant row or sentence from the response, then identify what must change and what should remain intact.

Audit the packet for invented tolerances, policy rights or manufacturing explanations. Keep only the repeated values and the confirmed comparison method.

Reduce the message to one question and a short factual context. Preserve the exact variant and chart reference, omitting unrelated personal details.

Review the output before using it

• Item and chart match
• Repeat route documented
• No invented cause or return entitlement

Confirm that every number stayed in the correct size column. A correct subtraction is not useful if the source values describe different routes.

Limits and the next real-world step

If method or variant identity is unresolved, clarify that first. Do not make the packet more persuasive by suppressing uncertainties or editing evidence photographs.

The assistant can organise the information you provide; its response is not independent evidence of current stock, exact fit, material performance or store terms. Check the actual listing or physical garment for those decisions. For an image task, written observations can supply the worksheet; this guide does not require or promise an automatic image-editing feature.

Save the final checked worksheet with its source notes, not only the last chat reply. When a fact changes, update that field and ask for the affected part to be revised. Keep the earlier record labelled so that an outdated observation does not quietly return as current evidence.

Use the practical method in What to Record When a Shirt Fits Differently From Its Size Chart to collect the real observations first. For related background, consult the relevant TryBuy shirt guide, then return to this worksheet for the specific AI-assisted deliverable.
