This is a long-sleeved shirt in a 165B size for a school uniform. Although it is a school uniform, the specifications are the same as a general dress shirt, so it can be used for business, formal occasions, etc. I received a large quantity from an acquaintance, so I am selling the ones I don't need for myself or my family. Therefore, it is only available while supplies last, and there will be no restock. It will be delivered in simple packaging. Please understand this beforehand. *Inventory status at the time of product listing* For men: 155B 160A 165A 170A 170B 190A 190B 195B are out of stock.
