Yunli is a young girl with a fair complexion, grayish-navy hair that is cut into a bob style, and two strands from the back tied into two long, low ponytails with golden ornaments, and golden eyes. She has a small golden hairpin on her right side, a large golden crown adorned with black, green, and blue orbs, as well as an earring on her left ear resembling a peacock feather. She also has red painted nails.
Yunli's outfit is reminiscent of those present on the Dunhuang (Chinese: 敦煌市) Murals located in the Mogao Caves (Chinese: 莫高窟). It consists of a black and white top with thin red straps that bares her midriff adorned with a golden center ornament, a white collar lined with teal, a red split cape, detached sleeves of similar colors, and a two-piece pleated skirt in both white and teal with gold embellishments. She is barefoot, and also wears various accessories, including a golden plate at her hip with yellow tassels, black and gold fingerless gloves, as well as red straps on her right thigh and left anklet both with golden jewelry.
