This is a denim jacket from Quoti Use Fith. It's thin and can be worn like a shirt, so I think it's useful even indoors＾＾ I've worn this about twice. It no longer fits me, and it's been stored at home for a while, so there are some fold wrinkles, but it's still wearable. It's currently not sold, so I think it's hard to get. The size is 130. Original price: 7,590 yen.
