Write size and fit copy for {{PRODUCT_NAME}} sold by {{BRAND_NAME}}.

Inputs:
- Size chart: {{SIZE_CHART}}
- Garment or product measurements: {{PRODUCT_MEASUREMENTS}}
- Fit notes from the buying team: {{FIT_NOTES}}
- Return reasons recorded so far: {{RETURN_REASONS}}

Produce:
1. FIT SUMMARY - one sentence naming the fit against a reference point the shopper knows.
2. SIZING ADVICE - a short block answering: does it run true to size, who should size up, who should size down. Base each answer on the measurements or return reasons, and say which.
3. MEASURED ON MODEL - a line stating the model height and size worn, using {{MODEL_DETAILS}}.
4. HOW TO MEASURE YOURSELF - 3 numbered steps for the measurements that matter most on this product.
5. FIT FAQ - 3 questions with answers under 40 words.

Rules:
- Never state a measurement not present in the inputs.
- Do not use vague terms alone. "Relaxed" must be followed by the measurement that makes it relaxed.
- If return reasons and fit notes disagree, say so plainly and recommend the cautious option.
- No em dashes.

Fill in before running

Replace each placeholder with your own detail. The more specific you are, the less the model invents.

Getting a better result

Return reason data beats the buying team's opinion. Say which source each piece of advice came from so you can audit it.
Put the size up or size down line above the size selector, not inside a collapsed tab.
If you sell the same block across products, generate once and reuse rather than regenerating per SKU.

Questions about this prompt

When is this better than adding another size chart?

When items come back for fit and the reflex is a more detailed chart. A chart gives numbers; this writes the sentence that tells a shopper what those numbers mean for them. Run it on products with recorded fit returns rather than the whole range, and reuse the block wherever the same pattern block repeats.

Which inputs does the sizing advice rest on?

The size chart, the actual garment or product measurements, fit notes from the buying team, recorded return reasons and the model height and size worn. Chart and measurements are different inputs and the prompt uses both. Without return reasons every piece of advice is sourced from opinion.

What comes back, and where does it belong on the page?

A one sentence fit summary, sizing advice that names its source for each statement, the measured on model line, three measuring steps and a short fit FAQ. The size up or size down advice with its source attached is the piece to place above the size selector, not inside a collapsed tab.

What goes wrong when fit notes and returns disagree?

Trusting the buying team over the return reasons where the two disagree. The prompt states the conflict and recommends the cautious option rather than resolving it, and returns data is the side that has been tested. Second, do not edit the measurement back out of a phrase like relaxed through the shoulder.
