'Fashion King' is a movie that follows the story of high school student Woo Ki Myung (Joo Won) who is known as a "bread shuttle", someone who is bullied into running errands for the class. He aims to transform himself in order to rival Won Ho (Ahn Jae Hyun) as the most handsome, stylish guy in the school and to attract the cold and unapproachable popular girl Hyejin (Park Se Young). Kwak Eun Jin (Sulli) is also an originally unfashionable student who secretly has a crush on Woo Ki Myung. She, too, attempts to change her style in order to get his attention.

The stills showcase Joo Won and Sulli's transformation process. While Joo Won's bowl haircut is certainly not his best look, Sulli's hair looks unkempt, creating a sloppy appearance for the usually polished idol. It seems that Sulli will go for a neater, cute, girl-next-door image as the movie progresses, however, as suggested by the bottom right picture, much to the relief of fans.
