Sleeve Width: 33 cm Back Width: 30.5 cm Front Width: 26 cm For work I asked my grandma to tailor it for me. It's an Oshima Tsumugi. According to my grandma, it seems to be men's mud-dyed fabric. With an extremely fine check weave, it looks plain from a distance, allowing you to enjoy a clean and simple look. Used only once After that, it was stored in a drawer. There are hook marks on the collar lining and hook stains, which seem to have occurred during storage, but they don't show on the front and you can wear it comfortably right away. Also, please understand that there are very faint signs of wear, shallow wrinkles, folding marks, and pressure wrinkles from storage before purchasing. Although there was no malice, I had a transaction with a complainer last month that made me feel down. Because it's not brand new, there might be some oversight that is not mentioned in the description. I ask again, if you are nervous, please consider carefully before purchasing. Oshima Tsumugi is light, easy to put on, easy to move in, and doesn't make you tired even after wearing it for a long time. And it's warm. I'm selling it at a low price, please take it in your hands and enjoy it. Thank you.
