I read the reviews and ordered M for 36- 38, but could have easily taken s. So, if you are 1,62 m & 60kg you schoul buy S, the item is a bit loose at the chest and waist area.
Size is true to fit. I am Small in American size and hesitated about the chinese size and I ordered Medium, As a result the swimsuit was a bit big for me, but that was my mistake.
