This is a 100% cotton haori (a traditional Japanese jacket). Since it's 100% cotton, you can wash it at home as much as you like. Also, although it's thick cotton, it's very stretchy and has good give. The original price was over 10,000 yen. The sleeves are roomy, so you can wear anything underneath. There are no buttons or fasteners; you can wear it by simply overlapping the front panels, or you can leave it open. There are pockets on both sides. I have washed it, but I have never worn it outside, so I'm listing it as "like new." What do you think?
