This is a navy linen jacket. It has a hook closure in the front and pockets. The hook design is a key feature! The lining only has cotton lining in the sleeves, which is helpful when you need to wear a jacket in the hot summer. The sleeves are three-quarter length. The linen has a slight sheen, but there are wrinkles that won't come out even after cleaning. We hope you enjoy it as part of the linen's texture. Purchased many years ago at a Daikanyama store. Thank you for looking.
