Purchased at a department store in Osaka. I may have removed the tag since I can't find it. I believe it's cotton. The design has a collar that stands up beautifully around the neck. I loved it very much, but I haven't had a chance to wear it, so I'm offering it for sale. I've only worn it a few times, but it's been stored at home.
