This is a one-of-a-kind sleeveless chanchanko (a type of padded vest) that my mother had someone make for her decades ago. It's been carefully sewn. The outer fabric feels like yarn, and the lining is quilted. I apologize if I haven't described the fabric well. There is no batting inside, so it's not thick and easy to move in. The armholes are roomy and allow for easy movement. I've taken measurements. Please check them. There's a large pocket on the right side only. I've included photos of the fabric in the 5th and 6th photos. I noticed while taking the photos that it seems like it could be worn reversibly. I thought this way might be better if you prioritize warmth on your back. This is just my personal opinion. It has been stored in a Japanese chest of drawers for a long time, so it has a camphor smell. Please be aware of this. Thank you.
