f(x)'s Sulli revealed in an interview with EDailySPN that she used to be the shortest member out of the five. She said, "Two years ago, I was 147cm tall. I was shorter than Luna." Now, Sulli is 169cm tall, which is above average for her age. She is also the tallest member in the group. Puberty has served her well. Sulli continued, "It's been over five years since I've arrived in SM Entertainment. Super Junior saw me early on and then saw me again later when time had passed. They didn't even recognize me because I grew taller." Sulli has earned the nickname Sulovely because she has such a lovely face. Is the name so appropriate for her? Here's a fun fact: The "Choi"s are the tallest members of SM Entertainment's idol groups. Talk about a weird coincidence... Or is it?
