Inpyeong’s clothing is based on the recently excavated Silla tomb, Jjoksaemjigu Tomb No. 44 (쪽샘지구 44호분). The National Museum of Gyeongju has conducted an archaeological survey of this tomb since 2014, and they published a final report in July 2023. This tomb was built in the late 5th century, and its owner is a young princess around the age of ten. The intricate pattern of Inpyeong’s clothing are from the princess’s golden shoes. Fragments of textile were found inside the shoes, so reconstruction of the complete fabric was possible. The checker-patterned clothing can be seen in tomb murals from Goguryeo, too.

The rug and hanging calligraphy in the background are based on the ones from Shosoin, Japan. These intricate 8th-century wool rugs, totaling forty-five, are the imports from Silla based on the accompanied documents.
