Yihwa has long black hair tied into a ponytail and pink eyes, with a light pink flower brooch in her hair. She wears a dark gray sleeveless zip-up dress that extends to her collar like a tracksuit, with a light gray sarong that's red-brown on the inside, with a dark flower pattern, and a red-brown rose brooch attached, and pastel brown pantyhose and black ballet shoes.

She keeps her past blushing and sassy behavior when embarrassed, but she's calm and dignified most of the time.
