Like all jackets this brand must take one size bigger; I make the M or L and bought an XL but I have no interest in putting a pretty thick sweater underneath: size just in the chest. I keep still for outings or I would put a thin garment below because this jacket has a thick lining: to walk and outputs it is perfect: for work I need a jacket or thick sweater he does not agree: I make a size 95D: this may explain it. In addition to retail, the quality is perfect.
