Returns data is a goldmine for pattern engineering. If a specific SKU has a 35% return rate, it isn't just bad luck—there is a structural grading error in your pattern block. A return audit will find and fix it.
1. Standardize Sizing Return Reasons
Don't just write "Incorrect size." Classify customer comments into actionable buckets: "Too tight in arms," "Too long in torso," or "Pinch at waist."
2. Adjusting the Pattern Blocks
If 60% of your Medium exchanges are for Large, your base measurements are running tight. Update your base specs for the next production run rather than adjusting the grading curve.
