K-pop girl group Wonder Girls will be making a comeback as a four member group with their third album, ‘Reboot’ on August 3.

JYP Entertainment released their teaser image today through the group’s official homepage as well as JYP’s official social networking sites.

In the teaser photos, the members are wearing one piece black swimsuits with a 80s retro style concept.

Last Tuesday, they released a teaser video that revealed each of the members holding a different instrument as well.

For this album, Wonder Girls’ participated in the making of all the songs except for the title track. They worked to bring in the 80s vibe of retro pop and slow jam for this album.

The group will release the album next Monday and hold a showcase later that night with their fans.
