EUC Coach trench coat black with satin type trim and Coach cover bag and hanger

Very nice coat. Nice lining. 2 outer pockets. Extra button. The trim looks like leather but it’s not. It’s like a satin feel material. My sister loved it but it was always a bit too small. Armpit to armpit is 18 inches. Total length is 34 inches. It says size 10 but I do think it runs small. Waist area buttoned is only like 32-34 inches.
