This is a Rokusan-do Kendo uniform. This manufacturer is no longer in business. The collar tag says 1L. Detailed size is unknown, so I've also included the measurements from a tape measure. Please note: Although it's difficult to see in the images, there is some discoloration near the fold at the bottom. It should be fine if you don't mind. I don't think it will come out even if you wash it. We cannot accept returns or exchanges due to size or product complaints, so please understand.
