Size: No label Three-quarter? Seven-eighths? Not long-sleeved. It's a knit-like material, but not quite. The reverse side feels like a cut-and-sew. There is a sense of wear. I have checked for stains and damage, but there may be oversights. Please understand. This is a used item. It has been stored at home. We ship as compactly as possible. Please refrain from purchasing if you are concerned.
