i'm looking to buy a couple of the shirts from the new casual line. however, in my experience, i found clothes from Japan/Asia to fit much slimmer/shorter than i am used to. I'm a 40/15.75 in most other euro and US makers, but according to the item's details, it advises a tokyo slim 39-40 to go with a medium. however, my chest is a little bigger for the size. so between my chest leaning towards a large (in spite of a smaller neck), this shirt having back darts and 2% shrinkage, i can't decide between medium and large.
