> 1 last thing; some global brands actually have the same size name on the same product represent a different size in different region (eg an SKU in size S in US may have different measurements to the same SKU in S in Asia)

I (Swiss) once ordered a T-shirt from a U.S. brand, size M because that fits me perfectly 95% of the time. It was way too big for me.

Lesson learned, the next time I liked a T-shirt form the same brand, I ordered the size S. It was way too tight, I couldn't even put it on. I checked the label, and it said: "European fit".
