Girl group f(x)'s Sulli revealed a naked face self-camera picture.

Yesterday, Sulli posted on her Me2day, "Airplane is too high~" along with a picture.

In the picture, Sulli has no makeup on with messy hair in the airplane. Her natural face looks like that of a baby boy.

Internet users who saw this commented, "The epitome of lovliness" and "No one has bette naked face than Sulli."
