[1] Since the 1894 reform, all varieties of po with wide sleeves, including the dopo, were prohibited to be worn by King Gojong and instead people had to wear the durumagi.

[3] According to Lee Eunjoo, the dopo was originally introduced from China but was localized in Korea through the integration of additional features.

[15] After the Imjin wars, the Joseon system of po (robes) was adopted which allowed the dopo and the durumagi (두루마기) (also known as juui) to be used as jangsam.

[15] According to Cho Geun-Hee, the name 'dopo' may have originated from China; however, the structure of the dopo was developed under the influences of other forms of traditional Korean overgarments.

[16] It is suggested by the author Myoung-Hee Lee that the dopo appears to have its origins from the robe worn in Goguryeo (고구려).

[1] Other authors such as Jungae Kim also suggest that it is the dopo could have originated from the jikryeong (직령/直領; coat with a straight collar) po and with which its bears similarities.
