Supi is a fashion select shop in Seongsu, Seoul, selling clothing from several brands alongside its own line. It runs as a pop-up space, and visitors walk through the revolving door at the entrance and browse and try on clothes up to the second floor. A Supi cafe of its own sits at the back entrance on the first floor, and various events are held there. The walkways are narrow and there are dangerous steps, so care is needed when moving around.
