Many idol singers left Korea today through Incheon Airport. It was for "K Collection in Okinawa," being held in Okinawa, Japan.

SISTAR's Hyorin wore a leather jacket with a white shirt underneath, showing off a chic airport fashion. It seemed that she was trying to avoid revealing her skin, but her volume could not be hidden through the V-neck shirt.

"K Collection in Okinawa," a combination of K-POP concert and fashion show, will be attended by Lee Seung Gi, Park Shin Hye, 2NE1, IU, SISTAR, After School, ZE:A, SECRET, TEEN TOP, FTISLAND, and more.
