This tunic has a longer length and a fairly sturdy fabric. The sleeves are wide and have a relaxed feel. There is one button closure at the back of the neck (with a spare button). It's a US size M, so I think it feels like a Japanese size L (please check the measurements when laid flat). No lining, no pockets, no stretch. Length: Approximately 84cm Width: Approximately 54cm *Approximate measurements when laid flat.
