Thank you for viewing the Iron Heart work shirt. The size is M. This is a standard Iron Heart product made of sturdy fabric. The color is beige, and it can be worn year-round, whether as loungewear, for going out, or for work (the pockets on both sides are very convenient). It has a nice color fade, and you can enjoy the aging process from here on out. Shoulder width: 44cm Width: 53cm Sleeve length: 62cm Length: 72cm Sleeve length: Long sleeve
