This is a long-sleeved shirt in a 150A 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 restocks. It will be delivered in simple packaging. Please understand this in advance. The types differ between Bird Line and vancool, and there are slight differences in chest size even for the same size. Please understand this in advance. *Inventory status at the time of product listing For Men: 155B 160A 165A 170A 170B 190B 195B are out of stock.
