Size as a dataset: aggregate buyer measurements
Veterans don't guess — they compile. Every buyer note with a height, weight, and taken size becomes a row. After enough rows, your size is a query, not a gamble.

Build a size table, not a guess
Collect buyer notes: '170/60 took L, perfect', '180/75 took XL, snug'. Ten rows per item type beats one tag. The cluster of takes is the answer.
Spreadsheets exist for this. One tab per item type, sorted by height. Your future self thanks you.
One shop's M is another's S
Sizes drift between shops, especially across Asia. Your table absorbs the drift because it's built from real takes, not factory labels.
The printed tag is a factory's opinion. Your aggregated notes are evidence. Trust the evidence.
Measure flat, compare to the seller
Lay the item flat, measure across, and compare to the seller's own numbers — not the size you grab in a Western store. Asian cuts run narrower at shoulder and waist.
Write the numbers in your table. 'Usually a Medium' is memory; the tape is fact, and the table is the record.
No swaps across the border
You're shipping through an agent from Asia. There is no 'swap a size'. Wrong size means a second order or a closet orphan. The cost of guessing wrong is real money.
That's why the aggregated notes beat the tag. Someone wore your size and logged it; read it like the only review that counts.
Shoes: size to the larger foot
For shoes, go by the larger foot and the cm foot length on the product, not the EU label that drifts between batches. Log the cm next to the taken size.
If the row has no size note, slow down and read reviews for fit. Guessing means a second order if wrong.
FAQ
How do veterans nail sizing?
They aggregate buyer height-weight-taken-size notes into a per-item table. Ten real takes beat one tag; the cluster is the answer.
How do I convert to my size?
Use the seller's own chart and the cm measurement, not a generic search. Asian factories cut to their chart, so a 'L' here may differ there.
What if there's no size info?
Slow down, read reviews for fit before ordering. A wrong size means a second order — no swaps across the border.
