What Size Assistant is for
In cross-border shopping, the most common "fails" aren't quality issues-they're sizing issues. "M" and "L" don't mean the same thing across countries, and seller charts can be inconsistent.
How to use with QC photos
Find usable measurements
Look for a ruler in the QC photo (laid flat) or measurement text in the listing.
Match the unit
Set the tool to cm or inch to match your source data.
Pick the correct category
Don't use a Pants chart for Tops. It will lead to bad decisions.
Choose your standard
Select the system you know best (US/EU/UK) to see familiar labels.
Compare against the range
If your QC measurement falls into the 'L' range, it's likely a Large. If it's on the edge, leave room.
Common ways people use it
Scenario A: Confirmation
You ordered size M. The QC measurement looks weird. Use the tool to check the typical M range and decide if you need to exchange.
Scenario B: Pre-order Safety
You see multiple QC records. Pick the clearest measurement, compare it here, and choose a safer size before you even buy.
Scenario C: System Conversion
You know your US size, but the seller uses EU. Use the tool to translate systems and sanity-check against real QC data.
FAQ
Practical Tips
- * Focus on the key measurement (chest for tops, waist for pants).
- * Think in ranges, not single numbers. Fit varies by brand.
- * Be conservative with slim-fit or non-stretch fabrics.
Important Notes
Size tables are reference guides. Actual fit can vary by brand, style, and batch.
If you are very size-sensitive, always request additional QC photos of key areas (shoulder width, waistband, etc).
