f(x)'s member Sulli showed off her sexy side.

In the photo shoot with COSMOPOLITAN released on Wednesday, Sulli posing in a pool and beachside.

Sulli is wearing a bikini while immersed in an emerald ocean. Her skinny waistline and long legs are also shown in the revealing outfits. Sulli has evidently lost weight since she was last seen for public promotion.

This pictorial can be found in the June edition of COSMOPOLITAN.
