False collar, beauty collar. I'm selling this because I don't use the type without a half-collar. It's a Kirakku collar that attaches to a Nagajuban (long undergarment) with a zipper. This is a beauty collar from ERIHIDES.

This does not come with a half-collar, so you will need to attach your own. Normally, you would insert a collar core between the base collar and the half-collar, but this is made of sturdy fabric, so a collar core is not needed. It's a half-collar with a zipper, so you can easily wear a kimono.
