Sistar's member Soyou showed off her perfect abs.

Soyou recently revealed a picture of herself online. This was revealed to have been taken while she was filming for a commercial.

In the picture, Soyou is wearing a very short pair of shorts and a crop tank top, revealing her perfect S line. The short tee also reveals her perfectly thin stomach with abs.

Soyoo's group Sistar will be coming back on June 11.
