Picked this up while in Iraq from a Ukrainian soldier. It is in excellent shape. Comes with liner. With liner in it is REALLY warm! I am 5'4 and 160lbs and it fits perfect with liner in. Without liner it is a little bigger on me.
I do not think it would fit you. It fits me just right and when i say it is a little big with the liner out, I mean just slightly. My issued field jacket from iraq is a medium short. It fits about like it...maybe a medium regular.
