For men's clothes, We recommend that you find one of your suit tops to measure. Or choose the size based on height and weight. If any part of your clothes, chest or shoulder width, falls at the upper end of a size range, or if your measurements happen to fall between two sizes, we suggest selecting the next larger size range for a better fit.
