Fits too tight at waist.
Size: XX-Large, Color: Wine
Quality of product satisfactory, however size labeling incorrect. I ordered a XXL that is too tight at the waist. It should be labeled XXL Trim.

Best Jacket ever…for a woman!
Color: Blue Gray, Size: X-Large
As an older woman whose body parts do not match many women’s jacket size (come on people, we are not all going to remain a size C high and dry) this Jacket is a godsend. Light but warm, INSIDE pocket with a zipper for keys and wallet (bye bye pocket book), sleeves with extra long cuffs so I am never cold ÀND comfortably tight so I can easily put my gloves on or off. Love the hood, the high neck collar and that it stays puffy all over ÀND not in bunches. The color is nice too.
