Thank you for viewing. earth Collar is neat. The front panel fabric is georgette, and the back panel and sleeves are T-shirt fabric with stretch. Size: Shoulder width: 63cm Chest width: 56cm Sleeve length: 40cm Length: 54cm (Measurements are approximate as they are taken by a layman) The front panel is made of georgette fabric for a neat look. The back panel and sleeves are made of stretchy T-shirt fabric. How about wearing it under a suit? There are no noticeable stains or damage, but I would like those who understand that this is a used item to consider purchasing it. Please feel free to ask any questions.
