This is a Kiraku hanjuban (half undergarment) that just arrived last week. I purchased a size L, referencing the sleeve length at the time of purchase. Upon opening it and comparing the collar to my existing nagajuban (full undergarment), I found that the neckline was larger than the nagajuban I had tailored to match my kimono. I'm afraid it won't sit right when wearing a kimono, so I'm unfortunately putting it up for sale. I've only had it open for a few days, and I've compared the folded collar to several nagajuban and tried removing the zipper. There's a slight crease from folding the zipper, but I haven't worn it. The zipper collar is a hiro-eri (wide collar), and there are no replacement sleeves. The photos show it folded. You can find more detailed information by searching for "Kiraku." Price: 14,300 yen * Although it's close to new, it has been handled by a person, and I have measured the dimensions with a measuring tape after opening it. * Please note that it will be shipped folded.
