Van Horns Navy Blue Partial Lined Suitcoat/Blazer - No Tags - Medium? Large?

Men's Navy Blue suitcoat or blazer from Van Horns Men's Wear. Light weight linen-type material. No size tag, so please read measurements carefully. Sleeve: 25" Jacket length (shoulder to bottom): 30" Shoulder - Shoulder to shoulder laying flat: 18" Waist - Width across at top button or waist: 20" Chest - Pit to Pit: 22" Based on the measurements my best guess would be a medium, but you will need to make the decision if it is a large or medium. Please ask any questions prior to purchase. Thank you for stopping by. Have a wonderful day.
