Rainbow's Jisook showed off her sexy body line.

On November 7th, Jisook tweeted, "The appearance of jean-Jisook" and uploaded a photo of herself posing next to a street pole in heels and skinny jeans along with a plain white shirt tied to reveal her midriff. The photo showed off her long, slender legs, thin waist and sexy body line, which was contrasted by her cute pigtails and facial expression.
