15& Baek Yerin, Seductive Red Lipstick

The female duo 15&'s member Baek Yerin revealed matured beauty.

On August 4, Baek Yerin posted on her Instagram, "Good night" along with a picture.

In the picture, Baek Yerin is leaning her chin on her hand, looking at the camera. Her pale skin and the contrasting red lipstick added sexiness to her.

Internet users who saw this commented, "Wow, her lip color," "I love your hair color, it looks so good on you," and "So seductive."

15& will be performing at the "2014 JYP NATION" concert on August 9 and 10.
