Color: Gray Sleeve Length: Long sleeve Pattern/Design: Solid Collar: Regular collar Material: Cotton Season: Spring, Summer, Autumn This is a shirt jacket by Masao Shimizu. I have worn it a few times and stored it at home. There are no noticeable stains, and it is in good condition. Made of crisp 100% cotton fabric, I think it's a shirt that's easy to wear in all seasons except summer. Please feel free to comment if you have any questions.
