Uniqlo and Hana Tajima collaboration item. A scarf is also included in this listing. The collar angle is very beautiful, and it looks great both open and closed with the zip. Regarding the scarf, as expected from Hana Tajima, it's 100% polyester, but the Uniqlo side also seemed to have put in effort, with a luxurious color scheme, resulting in a glossy feel and texture, which is why I bought it. Personally, I used it with kimonos, etc.
