Hyolyn and Dasom are less than a day away from releasing their special summer single!

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.

Check out the teaser image below!
