Hab 38 ordered because my other G-Star sweater same line fits well with 36/38 and beautiful falls loose. Unfortunately, this is cut here very powerful. It should indeed be oversized, but it looks like having a sack. Total wide and bulky. So necessarily a number buy less. S = 36 / 38th And then it's still far enough and the sleeves are also very long. The material is knit very thick.
