yeah, there is seperate sizing for the 'asian' (japan/hong kong/taiwan etc) vs 'western' (us/uk/australia etc) markets. generally speaking, a M in the asian sizing is a S in the western sizing. for tops, the asian sizing is usually cut slightly shorter on the body and sleeves too. occasionally a western store will get some asian stock (e.g. heattech) but it's usually rare due to the logistics that you mentioned.i wish they stopped changing the cut of the ocbds every season.
