Men's size 52 long black/charcoal gray suit jacket

Excellent condition fully lined suit jacket. Shoulder to shoulder is 21 to 21.5 inches, back length is 34 inches, pit to pit is 25 inches and 25 inches across waist at bottom button level. Sleeve is 27 inches. There is no size on this jacket. However it is big and tall/long. I would say it is a 52L based on measurements. Big men's jacket/big and tall
