Although she is the second youngest of girl group, f(x), Sulli is widely known for being the tallest member, and is one of the tallest females in the k-pop industry. Her height became a big issue after yesterday's Inkigayo episode, as she was as tall as the other two MC's, 2AM's Jokwon and CNBLUE's Yonghwa. The two noticed that she was taller than usual, and stated, "You look taller today.", which Sulli jokingly replied, "The air up here is quite nice." Netizens noticed the height difference between Big Bang's Taeyang and Sulli as the former collected his Mutizen award for I Need A Girl, and the snapshots of the two standing next to each other are called "Taeyang's humiliaton". No matter how high the heels were, no one can deny the fact that she is very tall. Yonghwa is said to be 180cm, and she was about the same level as him. Also note that her last name is Choi.
