Kkachi durumagi is a children's colorful overcoat in hanbok, traditional Korean clothing, which was worn on Seollal, New Year's Day in the Lunar calendar.

[6] In Korean mythology, magpies are regarded as auspicious messenger delivering good news but also a provider of prosperity and development.

For boys, blue color is used for the portions called git (깃, a band of fabric that trims the collar),[11] goreum (고름, strings at chest), doltti (돌띠, embroidered belt)[12] respectively and purple is used for mu (무, gusset).

On the other hand, kkachi durumagi for girls has red or purple colored git, goreum and doltti and dark blue mu.

[3] In old days, kkachi durumagi were worn as seolbim (설빔), new clothing and shoes prepared for Seollal, while at present, it is used as a dorot, a ceremonial garment for doljanchi, celebration for a baby's first birthday.
