vintage trench coat Juli de Roma 12 womens man made cashmere navy long mobwife

Vintage Juli de Roma “finest man made cashmere” coat Tag says it was from a fur shop in La Crosse, WI, which closed in the mid 80s so it’s at least that old. No material tag but I’m guessing it’s a polyester blend. Very soft with a satin feel to the lining. Missing a button on one sleeve, currently being held in place with a safety pin. In excellent condition otherwise. Size- 12 ptp- 21.5 sleeve length- 22.5 total length- 35 Material- none specifically listed
