On August 9 KST, the former SISTAR groupmates dropped a third image teaser promoting their upcoming single "Summer or Summer." In the image, the two look straight into the camera as they pose in sexy coordinated strapless looks. A lime green Jeep and some clay-tiled buildings can be seen in the background, adding to the fun warm weather theme.
Meanwhile, "Summer or Summer" is set for release on August 10.
