Abamama Hax has released a kind of buddhist stole (kasaya), the seven cloth-wide kasaya (hichijō kesa). It is wider and more elegant than the monks' usual five cloth-wide kasaya, and thus is usually worn by priests at memorial services. You can get it at this location in Kodama no Ki. There is an animation overrider available just next to it, so that you can straighten the style!
