Group f(x)'s Sulli grew up from an innocent girl to a sexy woman.

Today, Mnet "M! Countdown" was filmed in CJ E&M in Seoul.

On this day, f(x) held their comeback stage. They came on stage with checkered dresses or skirts and black stockings, throwing away their girl images and putting on a sexy woman one.

Sulli especially caught much attention as the innocent girl that everyone knew of was nowhere to be found, and instead was a sexy Sulli that had grown up.
