Girl group SISTAR's unit SISTAR19's Hyorin turned into 'Dark Hyorin.'

Yesterday, SISTAR's agency Starship Entertainment posted on its Twitter, "Hyorin who dyed her hair black for SISTAR19's comeback. How's dark Hyorin?" along with a 4-cut photo.

In the revealed picture, Hyorin wore a white outfit that revealed her body line. The black hair seemed to match her tan skin.

Internet users who saw this commented, "Success," "SISTAR19 charisma the best," and "Hyorin has the best body."
