Soprano Jo Su-mi appeared in a dress themed on Korea's national flag at the inauguration ceremony of President Park Geun-hye on Monday morning.

The national flag, or taegeukgi, consists of blue (yin) and red (yang) diagram on a white background representing purity and love for peace, and four black trigrams standing for changes and development of yin and yang.

Jo sang the national anthem clad in the four-color dress designed by haute couture designer Seo Seung-yeon, who has made dresses for Jo since 2010.
