1. Find the chart for the selected model
Confirm that the chart applies to the model and option you are considering. Note its units, size system and measuring instructions. Ask for a chart when the listing supplies only a size letter or number.
Keep the chart with the product link so that a later change of model does not leave you using the wrong measurements.
2. Identify what each number measures
For clothing, check whether the values describe the body or the garment. A laid-flat chest width and a full chest circumference are different measurements.
For footwear, distinguish a regional size label from a stated foot length or insole length. Use the definition given in the exact chart; the CM number on a box is not automatically a foot-length measurement.
3. Compare the same points and units
Lay a comfortable garment flat and measure it using the listing’s marked points. Note the chest or waist width, body or leg length, and any sleeve or rise measurement that matters to the fit.
For shoes, follow the chart’s foot-measuring method and consider any available width information. Keep observations about one model attached to that model.
- Tops: chest width, body length, shoulders and sleeves.
- Trousers: waist method, rise, inseam and leg opening.
- Shoes: size system and the definition of each length.
4. Resolve the measurement that decides between sizes
If two options are close, ask for the specific missing dimension. Explain the fit you want and use your reference measurements to make the question concrete.
Record the chosen size and chart before payment. Our catalog has no structured garment measurements from which to calculate an automatic size recommendation.
