I purchased this a while back and have not had a chance to wear it. It is in New-with-Tags, clean, unworn condition. It is a size 39 and fits most closely to a skinny-fitting size medium. Chest measures 20.25" from armpit to armpit. Sleeve measures 26.25" from shoulder seam to end of sleeve. Shoulder is 17.5" from shoulder seam to shoulder seam. Shirt is 32" long from base of collar to bottom of shirt (measured down the middle of the back).
