This is an M-size long-sleeved shirt from INGNI! It's a checkered pattern, and you can change the sleeves to three-quarter length when it's hot, so how about it for the coming season? It's a little used, but I think you can still wear it. For those who understand that it's used. Measurements are taken flat: shoulder width 39cm, body width 53cm, length 63cm, sleeve length 55cm.
