This is a collarless jacket from Onward (J.PRESS). With its structured design, it can be worn not only for work but also for small ceremonies such as graduation and entrance ceremonies. The size is 11 (equivalent to M-L size). It's new, only tried on. My mother bought it, but she has no plans to wear it, so I'm selling it. The original price was 36,000 yen, so it's a great deal!
