Forecaster of Boston Belted Rain Trench Coat Jacket Sz 11/12 Vintage

Vintage size 11/12 so probably more like a size 9/10 now. Not sure of material, very soft like a soft felt, maybe polyester?  Flattering coat. I never wore as a raincoat but rather like a light weight spring and fall coat/jacket.  One cuff the buttons are broken, cuff buttons not functional just decorative.
