Group Wonder Girls' member Yoobin showed off her sharp chin line through a self-camera photo.

Yesterday, Yoobin posted on her Instagram, "I started Instagram" along with a picture.

In the picture, Yoobin is sitting in the driver's seat of a car, smiling at the camera. The sunglasses she was wearing took up more than half of her face, proving her small head size.

Internet users who saw this commented, "Her face is really small. She's getting prettier and prettier," "What a fashionista," etc.
