You would think since this is a women's coat, this should fit a women's figure.  Nope.  I have an hourglass shape and normally wear an XL.  I bought it a size bigger to be safe, but it was still tight on the hips and chest, yet too big in the shoulder area.

If you have a boxy, small frame, this should work for you. Otherwise, you'll need three sizes bigger and will have to have it tailored!
