More than 1,000 hanbok appear in the film, with actress Park Shin-hye wearing 30 intricately embroidered pieces. 1 billion won (dolars909,000) was spent on costumes, a significant portion of the film's 7.2 billion won total budget. Costume designer Jo Sang-gyeong said she was inspired by the clothing during King Yeongjo's reign (1694-1776), which according to historical records was when a short jeogori, the jacket that sits on top of the dress, and jar-shaped skirts started to become fashionable.
