A jobawi is a type of traditional Korean winter cap with earflaps which was worn by women and was made of silk. Since its first appearance in the late Joseon period, it has been widely worn as a substitute for the ayam (a cap with a big ribbon on the back). Although the jobawi was worn by the upper class as well as by commoners, it was mostly used by the yangban aristocracy of that time as a decorative headgear when they went out. In addition, the jobawi was worn not only as formal headgear, but also for special occasions. Even though a wearer was not in formal attire, if she wore a jobawi, the overall outfit could be considered as simple formal clothing.
