Girl group SISTAR's member Soyou flaunted her sexy figure.

On Monday, Soyou posted a new picture on her Instagram. 

In the pictures, Soyou is squeezing her body into a tall and narrow locker. She is wearing a short dress and the tight fit of the dress draws the attention to her great shape.

On a side note, SISTAR recently finished the promotional activities for their song "Shake It."
