This is a vintage 1960’s mod fun fur coat. It has a double row of big black plastic and brass buttons, and has rounded collar and straight cut loose fitting body. The coat measures 40 inches actual bust but recommended to be worn by 36 inches bust or smaller by 34 inches (since shoulders are cut narrow). Sleeves are 21 inches and total length back neck to hem is 36 inches. Actual garment hips are 42 inches but recommended for about 36/38 inches. I would guess this to be about roughly modern size 6.
