Saekdongot is any hanbok patchworked with colorful stripes. It began to be made since the Goryeo period (918 – 1392). The name literally means "many colored clothing". It was usually worn by children of the age at one to seven year old. The saekdong can be applied throughout jeogori (short jacket with sash), majoja (buttoned jacket), durumagi (overcoat) or among others.
