They have been missing from the k-pop music scene as of late but with their comeback soon to come, f(x)'s Sulli teases fans by showing a more grown up image of herself for the May issue of InStyle. For this particular photoshoot, Sulli ditched her typical "younger sister" image and went for a whole new grown up look. With a mix of gray and black and tying her hair, Sulli pulls off a nice corporate female boss in charge look. Of course she adds a nice sexy taste into the mix that just screams of "I'll give you an early Christmas bonus" - wink wink. But guys and for some of you gals, hold the phone! Our dear Sulli is only 16 years old and unless you want to end up in prison tossing the salad, you might want to just check out the photos below to admire...and maybe pet the screen. [gallery]
