This is a Tornado Mart collarless jacket purchased at a used clothing store in Tokyo. The silhouette is slim, but the size is LL, so it can be worn with a comfortable fit. The wearer is 170cm tall and weighs 65kg, and the size was just right. It uses goatskin, which feels good against the skin and has a luxurious feel. It has a simple and minimal design, so I have found it very useful. I am selling it to declutter my belongings.
