For me the size corresponds to the French size, just may be slightly larger. I advice to take the size you are taking usual knowing that shirt it is not elastic (do not shake) and the cut is straight. Otherwise good product, and soft tissue okay, I already washed 4-5 times. This is true that even those unfamiliar with the series sinterrogent (and you wonder, you better be prepared) to the chemical formula. The purple color is original but can tire quickly, Jirai rather on sharper colors.
