This is a Swedish military sleeping shirt. I purchased it at a used clothing store some time ago. It's likely been dyed, and the color is navy, making it easy to match with other clothes. Perhaps due to the dyeing process, the buttons are purple, which provides a nice accent. The top button fastens with a loop. The size is 41, but it's difficult to see. There are no noticeable scratches or stains, but please understand that this is a used item. I am 171cm tall and weigh 65kg, and I wore it oversized. Shoulder width: 48.5cm, Body width: 61.5cm, Sleeve length: 60.5cm, Length: 83cm - Color: Navy - Button color: Purple - Design: Long-sleeved shirt Thank you for looking.
